Common Invasive Plants In Zone 7: Learn About Zone 7 Plants To Avoid


The problem with invasive plants is that they propagate too easily. That enables them to spread quickly from backyard cultivation to the neighbors’ yards and even into the wild. It’s generally a good idea to avoid planting them. What are the invasive plants in zone 7? Read on for information about zone 7 plants to avoid cultivating in your garden, as well as tips on invasive plant alternatives.

Zone 7 Invasive Plants

The U.S. Department of Agriculture developed a zone system dividing the nation into zones 1 through 13 based on the lowest annual temperatures. Nurseries mark the plants they sell with their appropriate zone range. This enables gardeners to readily identify plants hardy for their regions.

Most areas of the country have some invasive plants that grow well there. This includes zone 7, those areas of the country where the low annual temperatures range from 0 to 10 degrees Fahrenheit.

Zone 7 invasive plants include trees and shrubs as well as vines and grasses. You may want to avoid planting these in your backyard, since they will likely spread from their garden beds to the rest of your property, then into nearby land. Here are some of the most common zone 7 plants to avoid:

Trees

You may be surprised to learn that invasive plants in zone 7 include a number of trees. But some trees simply spread so fast you can hardly keep up with removing them. One such tree has a delightful-sounding name: tree-of-heaven. It’s also called ailanthus, Chinese sumac and stinking sumac. The tree propagates quickly from seeds, leaves and suckers and is very difficult to control. Invasive plant alternatives for the tree-of-heaven include native sumacs, like staghorn sumac.

Albizia julibrissin, also called silk tree, mimosa, and silky acacia, was introduced as an ornamental and planted for its feathery pink flowers. But you may quickly regret the decision to plant it, as little trees sprout every year all over your yard, even after you chop down the original.

Invasive plant alternatives are not hard to find for trees. Instead of planting invasive non-native species, substitute these with native species. For example, instead of invasive Norway maple, plant native sugar maple. Eliminate the invasive Japanese angelica tree in favor of native lookalike devil’s walking stick. Plant native red mulberry instead of invasive white mulberry.

Shrubs

Shrubs can also be very invasive. If you live in zone 7, here are a few shrubs you are better off leaving out of your garden.

Ligustrum japonicum, also called Japanese glossy privet, produces drupes that wildlife appreciate. However, thanks to these hungry critters, the plant will quickly spread into woodlands. It crowds out native understory plants and can even disrupt hardwood regeneration.

Many types of honeysuckle, including amur honeysuckle (Lonicera maackii) and morrow’s honeysuckle (Lonicera morrowii) take over all available space and develop dense thickets. This shades out other species.

What should you plant instead? Invasive plant alternatives include native honeysuckles and bushes like bottlebrush buckeye, ninebarkor black chokecherry.

5 Invasive Ground Covers to Avoid

Ground covers definitely have their place in the landscape, but they need room to roam. No border, no matter how deep, is going to keep them in check and mowing just makes them shorter they do not disappear. Yet very often gardeners will plant a fast-spreading ground cover without really giving thought to what it will do in the future. They are looking for instant impact and fool themselves into thinking they will stay on top of keeping it in check.

Compounding the problem is the fact that these aggressive plants are still widely available for sale. While the following 7 plants are often sold in garden centers, they are true garden thugs. Left on their own, they will take over. If you don’t want to be ripping them out for years to come, resist planting them in the first place.

In some areas, plants like these go beyond aggressive and become invasive. Check the list of introduced, invasive, and noxious plants for your state, before you let one of these plants ​on the loose.

A word of warning: these plants are popular pass along plants. Your friends may mean well, but the reason they have extras to give away is that these plants are such rampant growers.


Established Threat Many species in this category are archetypal invasive weeds known by every land manager, but all are widely established across Tennessee. All taxa assigned to this category have been reported from more than 10 counties. These taxa cannot be eradicated on a landscape scale using methods currently available, but officially designating the plants as invasive may serve to educate the general public and give land managers support to eradicate the species where appropriate (i.e. high quality natural areas, in tandem with rare species management, part of public engagement/citizen science projects, etc.). In addition, designating the species as a threat may push industry and state/federal agencies toward less invasive alternatives in landscaping and revegetation, thereby helping to avoid the next serious exotic plant escape.
Emerging Threat Species in this category have been previously reported from less than 10 counties in Tennessee, but are known to invade and disrupt natural plant communities in adjacent states. Theoretically, the early detection/rapid response model could be used to eliminate infestations or reduce the spread of these species in Tennessee. In addition, the act of listing these plants, many of which are relatively obscure in Tennessee, will help the land managers and the general public to recognize these species in the field.

I have just recently received a baby Tradescantia and I love it. The person who gifted it to me grew it from a cutting and it was Rooted in water. I potted it with commercial “cactus and succulent” soil, it’s what I had.
It’s two weeks later and every morning for three days, I find little white fuzz along the edges of the leaves. Just the edges. I washed it off of course.
I would send a photo but I don’t know how.
It does not look like a living creature, it has no legs, etc.
It looks like tiny flecks of chalk.
Help!

I suppose if you ignore this plant for a few years it might get out of control, but it's not as quickly invasive as other types of plants, like vines. Mine popped up from a neighbors little patch. After a couple years I decided to move them to a confined shady area to see how they do. I love the purple. Hopefully they do well there and continue to be slow growing.

Luckily, I don't seem to be allergic to this plant.

On Mar 16, 2016, coriaceous from ROSLINDALE, MA wrote:

Many of the comments describe a very common sterile dwarf cultivar. The species typically grows 12-18" tall and has leaves 6-12" long. At least in Florida, the dwarf cultivar is the more common landscaping plant. Because it is sterile, the dwarf is not a serious threat to natural habitat as the species can be, and it makes a great groundcover. Its rapid spread means it's not a good neighbor in a mixed planting.

The white flowers aren't ornamentally significant, as they're hidden beneath the foliage. Pink-flowered plants are T. pallida 'Purple Heart'.

All forms need good drainage, and do better with less water in winter---it's semi-succulent.

In a garden I worked on in West Palm Beach, FL, I found seedlings springing up all over the place, often . read more at a considerable distance from the parent. The tiny seeds are believed to be airborne, and can start plants in walls and on palm trunks. This species is aggressive in the garden as well as a threat to the Florida environment. If you like the look, grow the sterile dwarf cultivars in your garden.

The Florida Exotic Pest Plant Species Council included the species on their 2015 Category II invasive plant list. In Australia, the Queensland government considers it an environmental weed. Native to southern Mexico, Belize, Guatemala, and the Caribbean, it is widely naturalized in southern Africa (i.e. Kenya and Tanzania), temperate Asia (e.g. China and Japan), the Seychelles, La Reunion and on some Pacific islands, including Hawaii.

The species is commonly spread through careless disposal of roots and stems as well as by seed.

We live in the Coachella Valley. This is a part of the hot arid Sonoran Desert. 3 years ago we planted Trandescantia spathacea or Moses-in-a-basket because my wife liked it. We knew nothing about it and didn't know if it would grow here. It was planted under a pygmy palm and against a block wall with too much shade. For a year and half it got too much water and we ignored it. It lived thru the winter and summer. Recently, I admired it for it's determination to live so decided to learn more about it and encourage it. We now keep it drier and give it more light and it is now even more attractive than ever.

Auckland, New Zealand, zone 9b/10. Saw this plant groing in someone's yard and loved it. So planted a small one in the garden. It kind of just sat there over winter but once the weather warmed up it started to take off, and now I am thinking it's going to need a bit of control before too long to stop it taking over. Various websites say it only grows a foot tall, but it seems to be about double that, it's loving our climate.

I wondered why I hadn't seen this beautiful plant in Southern California gardens. Now I know. I bought three at a big box and planted them in an area that gets partial sun, even in the winter. I was careful not to water overhead, and kept them moist. They lasted for a while, but the minute we had a very light frost, they began to decline. The weather warmed up, and they continued to decline. Sunset listed them as being a tough plant, but that has not been my experience here in Pasadena (21 Sunset, 9a USDA). I think the soil in California may be too heavy, though this plant might be okay in beachside communities here. I don't know if they are dead to the roots yet. I'm leaving them in situ.

While I love this plant for its clumping ability, and thus it will cover a large area with time, I am severely allergic to the plant and have been advised to completely coverup when gardening.
Wherever the plant touched my skin a break out in a raised reddened area. Even more weird - I also get these red itchy patches where I haven't had direct contact, but only after direct contact. For example, today I purposely rubbed the plant on my forearm as a test and came out in a red rash at that spot, but also on my upper thigh.
I'm highly amused to read that dogs commonly are allergic to this plant.

I bought this plant for the purple color and pretty pink blossoms but did know much about it. Planted it in a large pot by the walkway and have enjoyed it. I have a dashund that has been to the vets several times over the past few months with sores from scratching on his stomach & back. The Dr. knows he has an allergy & asummed it was from the yard grass. He has been on steroids, antibiotics, creams, twice in 3 mos. He's fine in the front yard. After hundreds of dollars & reading this I do think I know now what his allergy is from. Thank you so much.

Extremely aggressive. Taking over my garden, although I had it pulled out about a year ago. It has reseeded itself and continues to grow from the rhizomes left behind. I am in the process of doing the job myself and taking out the rhizomes and as much of the roots as possible. It is very difficult to get all the little seedlings carpeting the ground. The worst part is that it seems that I am allergic to the plant. I developed a rash similar to poison ivy. I know what poison ivy looks like and do not have any in the area where I have been clearing up the oyster plant. I have no dogs, which I understand to actually be allergic to this plant. I had this problem before and that was the reason why I hired workers to clear this pest. Has anyone heard of contact dermatitis from oyster p. read more lant?

I haven't had this one long enough to make any judgments as to how my experience is. I can see for reading the other comments it could be a problem. Since I have dogs and it can become invasive I will keep it in pots and see how it does. I may change my notes on this later.

I think this is a lovely houseplant here in Nebraska. I received it as a college graduation gift from my great-Aunt. It was originally my great-grandmother's. My only problem is that the shape has really changed since I've had it. It's gone from more compact and bushy to very spread out. Does anyone know of a way to prune it maybe to get it back to the compact fullness that is so pretty with the purple leaves?

For many years I thought that the oyster plant was a harmless plant that provided good ground cover along fences in Florida. Recently my dog, I discovered, has developed a horrible allergy to this plant. Her underside breaks out in a rash which is hard to control. After a week long regimen of benadryl and steroids the itchy rash subsides, but the steroids cause other complications (uncontrollable urinating and an increased appetite). And then if we are unlucky enough, she manages to get into the plants again while playing with the neighborhood squirrels.

I do not recommend this plant in any yard that has house pets that like to travel along the fence where the plant likes to grow. The plant has juices that can cause burning and itching to human skin as well.

I grow this as a houseplant up here in Indiana. When I put it outside for the summer, it really gets full and bushy and full of its little flowers.

I see this plant far too often to find it pretty. It pops up everywhere here if there is another oyster plant nearby. There are pups completely covering the ground in some of my beds, whether it be in shade or in sun. If they had blooms like bromeliads, I might change my mind about the plant. :)
As it is, the white blooms are hardly noticeable, and now that I know it spreads by seeds I find them even less appealing! Please show sympathy for Floridians by taking some home with you after you've visited us.

I have to say I like this very attractive and "well groomed looking" plant, but can tell in the few seasons I've grown this species there is the distinct possibility it could become invasive as far north as extreme north Florida (8b-9a). Mine is well contained within concrete barriers and wooden fences, but it does quite fine here hard on the Georgia state line -- even in shady and damp conditions. It spreads nicely, but not aggressively in a fairly low light situation. I can only imagine what it might do in the hot, dry climate it apparently prefers. A couple of severe freezes (multiple nights in the low to mid 20's) here in N. Florida only knocked it down a bit --- it came roaring right back in the spring from the roots. Thanks to all who warned about it aggressive tendencies.

Boatlily, Moses-in-the-Cradle or Moses-in-the-Basket or Oyster Plant (Tradescantia spathacea) is highly invasive in the U.S. in disturbed areas, coastal strand, vacant lots, around old buildings as well as in very many natural habitats in central and southern Florida from zone 9a south along both coasts through the Keys, Bahamas, and parts of the Caribbean, where it also is invasive in some or many areas. It is fast-growing, propagates by underground roots and runners (also often by seed), and quickly invades and colonizes disturbed sites such as around old or abandoned buildings, in the cracks of sidewalks and concrete, and in vacant, weedy or undeveloped lots as well as very often in parks, nature preserves and natural habitats, crowding out other low native groundcovering vegetation and. read more preventing germination of native plants by forming thick groundcovers and spreading over the ground, crowding out and preventing germination of native species. If not controlled, it quickly gets out of control in the garden and spreads quickly by runners and cuttings and new seedlings, spreading out of yards into all surrounding habitats, including natural areas, remnants of natural vegetation, and onto other yards and properties. It is listed by the Florida Exotic Pest Plant Council's Pest Plant List (FLEPPC) as a Category One Invasive due to it's nearly uncontrollable spreading into surrounding areas, whether disturbed or natural habitats and/or preserves. It is very invasive especially near the coasts of southeast and southwest Florida in Miami-Dade, Broward, Palm Beach and Martin and St. Lucie counties as well as along the entire southwest coast of Florida from Pasco and possibly Hernando counties and the Tampa Bay Area southward. It is also extremely invasive in the Keys on undeveloped lots, in coastal strand, on roadsides and roadside borders, along fences and natural havitats and in natural habitats such as sandy coastal areas (disturbed or undisturbed), hammocks, sunnny sites, and on the backside of natural beach dunes. It also quickly colonizes sites along the Intracoastal Waterway in Florida as well as in all previous areas described all from zone 9a (central Florida) south through the rest of the state and the Keys. Please, DO NOT PLANT THIS PLANT IN CENTRAL AND SOUTH FLORIDA AND ANYWHERE ELSE WHERE IT CAN BECOME INVASIVE!

MORE FACTS - Quickly colonizes and is often very invasive in areas such as weedy vacant lots already colonized by other exotic invaders listed by the Florida Exotic Pest Plant Council on either of their Category One and Two Pest Plant Lists, such as Latherleaf, Carrotwood, Brazilian Peppertree, Snake Plant or Mother-in-Law's Tongue, Australian Pine, Earleaf Acacia, Wandering Jew or Inch Plant, Orchid Tree, Javanese Bishopwood or Bischofia, Arrowhead Vine, Golden Pothos or Devil's Ivy, Rosary Pea, Asparagus Fern, Air Potato, Strawberry Guava, Guava, non-native species of sword ferns such as Asian Sword Fern and Tuberous Sword Fern AKA Boston Fern (both are FLEPPC Class I Invasives and are members of the genus Nephrolepis), as well as many other invasive exotic pests in central and south Florida. Found from central Florida (zone 9a, including and especially along both coasts and on the barrier islands) southward through the rest of the state and the Keys. Invades vacant lots, disturbed sites such as sidewalk cracks, concrete gaps, edges of yards and properties, around old or abandoned buildings (e.g., houses, warehouses, etc.), as well as many natural areas and habitats such as coastal strand, coastal barrier islands, coastal and inland dry areas or scrub, sandy areas, along beaches on the protected back ridges of natural dunes (commonly invades those habitats) as well as many other or nearly all natural habitats except very wet or wet habitats in it's established and highly invasive distribution in central and southern Florida and the Keys. Does well in areas near the coast and on the backsides of dunes, where it can become very invasive like in Florida and parts of the Caribbean and Bahamas and Hawaii. Here is where it is found and/or is invasive:

WHERE IT IS FOUND/INVASIVE IN FLORIDA:

WHERE IT IS INVASIVE AND FOUND IN SOUTH FLORIDA (BY COUNTY):
Indian River
St. Lucie
Martin
Palm Beach
Broward
Miami-Dade
Monroe (the Keys)
Collier
Lee
Charlotte

WHERE IT IS FOUND/INVASIVE IN CENTRAL FLORIDA (BY COUNTY):
Sarasota
Manatee

Pasco
Hernando

FLEPPC (Florida Exotic Pest Plant Council) Category One Invasive!

OTHER AREAS WHERE FOUND:
Bahamas
Caribbean
U.S. Virgin Islands
Puerto Rico
Hawaii (U.S.)
Louisiana (U.S.)

Loves alkaline or slightly to moderately salty (dry and/or sandy) soils. Grows very quickly in those types of soils, which are plentiful in Florida, the Caribbean and Hawaii (also may be a pest in Hawaii and parts of the Caribbean and in much of or all of the Bahamas). Named after the small white flowers inside a "cradle" or "boat" (hence the common names Moses-in-the-Boat, Moses-in-the-Cradle and Moses-in-the-Basket and Boatlily). Useful as a houseplant, but please DO NOT PLANT THIS PLANT OUTSIDE IN AREAS SUCH AS FLORIDA AND OTHER AREAS WHERE IT CAN BECOME VERY HARD TO GET RID OF AND INVASIVE!

See my photo and other photos also for this species.

To MotherNature4 - When I checked the FLEPPC website and ISB Atlas of Florida Vascular Plants it shows that it still is and is on the 2003 Pest Plant List in Category One. Maybe you overlooked it.

The City of Anniston planted it last year in the median of one of the main throughfares and around the entrance of one of the city buildings. I couldn't believe they came up with this plant when usually it was some other everyday plant for this area. I wanted to go and ask for them during the fall because they dug them up and I haven't seen them since. So who knows where they are now.

This is one tough plant! In St. Petersburg, Florida you can often find it growing at abandoned or boarded up businesses, like an old service station for sale, or a building waiting to be torn down, where the plants can live for years surrounded by concrete, just on rainwater.

In a regular garden it makes a very attrractive and colorful groundcover for a sunny spot, which can be a difficult situation in such a hot climate. I didn't realize that it would grow up here in Northcentral Florida, zone 8b, so I am going to give this old favorite of mine a try, probably as a groundcover under white crepe myrtles, along with some blue agave, out by my gate to the dirt road--probably the most difficult situation on my property, because it gets hot noon-day sun, and car fumes and whit. read more e dust from the road when its dry--but I can't remember the last time it was dry around here.

I never noticed that this plant was invasive. I think it will be fine along the side of the driveway, where the truck tracks and an occasional mowing of the sandy driveway will keep it in check, and the area behind the planting goes into deep shade, which it won't like. In fact, I'm hoping the plant will cover quite a lot of ground, as I have a jungle of ugly "natives" like poison oak, Virginia creeper, and monster trumpet creepers that will have to be beaten back in order to plant this bed.

There is a reason people have cultivated plants for over 10,000 years, and that reason is that the native flora provided an often subsistance living for just a few people, and that "living" was gone when the climate changed, or a plant disease struck. So "native" does not always mean better. Of course we should protect our endangered native plants, especially those that are valuable to wildlife, but lets all use some common sense about this whole "native vs exotic" controversy, especially in the garden, which by definition is a place controlled by people, for our benefit. And the arbitrary definition of a "native" as a plant existing in the USA when Colombus discovered America virtually ignores the fact that idigenous people were farmers themselves, especially the Eastern Tribes (I'm one-eighth Cherokee), and that there had been thousands of years of contact between Europe and the Eastern Coast of the USA--the Cherokee are noted for their tall, Viking like bodies and often had blue eyes. So let's face it--everyone's a mongrel to some extent, and it's all to the better--it's healthier. No species or ecosystem can be kept "pure" or static in time--both plants and people are always evolving, and "All is change."

After planting quite a few Oyster Plants outside my home I discovered, via The Native Plant Society, that this plant is highly invasive in Florida, propagating by spreading and by air-carried seed to places far from the original plant. As it spreads it covers the ground thickly and prevents other tree and native plant shoots from coming up. If you live in FL please take this seriously.

esta planta es muy apreciada en el sur de Mexico por sus virtudes como curativa. En Mйxico es conocida con el nombre de Maguey morado y es utilizada en cataplasmas para curar heridas o infecciones. El jugo de sus hojas asadas es utilizado para desinfectar. Yo considero que ademбs de ser curativa es una planta bella por su color y la rareza de sus "espatas". En ЁMйxico esta planta es reproducida por vбstagos y no por hojas, y yo considero que crece mejor en sombra brillante o a la media sombra.

I divide my rhoeo by tranplanting the suckers. I have never heard of propogation by leaf cuttings but could be worth a try!

I recvd a small portion of this plant from a nearly dead mother plant which was left for several weeks in a home w/ no water. Very hardy plant as we still found green on this otherwise dried out husk. Not knowing at the time what type of plant it was, I placed this small green leaf in water to root. This plant took off, rooting after a week or so, and continues to be a welcome addition to our home nearly two years later. Seeds may be harvested by plucking the pods and allowing them to completely dry out. Seeds sown in soil will begin new plants. You may also propogate by allowing leaf cuttings to root. Very hearty and easy to grow!

Stems to 8in high. Leaf tufts frow to 6-12in. wide, with a dozen or so broad, sword-shaped, rather erect leaves that are dark green above and deep purple underneath. Flowers are interesting rather than beautiful the small, white, three-petaled blooms are crowded into boat-shaped bracts borne down among leaves. Selection 'Variegata' has leaves stiped red and yellowish green.

Avoid overwatering try to keep water out of leaf axils. Tough plant that takes high or low light intensity, casual watering, low humidity, and heat. Plant most often grown in pots or in hanging baskets grown as ground cover and edging in Florida.


Common orange daylily

Another plant with a spread that is very difficult to control, common orange daylily has striped (not spotted) trumpet-shaped flowers that point up. It is also called tiger lily, tawny lily or ditch lily. Daylily should not be confused with two orange natives: turk’s cap lily (also called Michigan lily) with a flower that points down, and prairie lily (also called wood lily). Both of the native lilies have spotted flowers. A good replacement for invasive daylily is native butterflyweed (Asclepias tuberosa), an important host plant for monarch butterflies, with showy orange flowers for sunny, well-drained soil.

4 | Creeping Phlox (Phlox subulata)

Phlox subulata ‘Candy Stripe’

Zones: 3 – 9
Bloom time: Spring
Height: 6″
Spread: 2′ to 3′

First on my list of full sun perennials is Creeping Phlox or Moss Phlox (Phlox subulata).

It is a low-growing ground cover that is easy to grow and looks beautiful at the front of your sunny border or spilling over stones in a rock garden.

Phlox subulata ‘Emerald Blue’

Once it gets going, it will cover the area with pretty white, blue or pink flowers in the spring, and looks beautiful with daffodils or tulips growing through it.
