Multiplication of coquelourde

The coquelourdecan be multiplied in two different ways. If you are the patient type, then you will prefer the sowing. On the other hand, if you are in a hurry and want a quick result, in this case proceed by division.


You have two choices:

  • Either you let the coquelourde reseed itself by direct sowing to obtain a natural result.
  • Either you control the operation by collecting the seeds. You can then sow in April in a mixture of potting soil and sand. Then water without excess and, in the fall, you can transplant the plants you have obtained.


The other option to get more feet from garden coquelourde consists of to divide the perennial in several plants.

  • Pull up the plant in the fall with a garden fork and break up the root ball, being careful not to damage the roots too much.
  • Then plant your newly obtained feet.

Our advice: if you live in an area where the summers are rather dry, it is not advisable to perform the division in the spring. In fact, your plant will not then have the time necessary to recreate a root system that will allow it to cope with the lack of water.

Slugs and snails happily feed on the leaves of the agapanthus, otherwise it is not really fragile.

The agapanthus works wonders at the edge of the path, at the foot of a wall or a fence, but also in beds or in large pots to adorn a terrace for example: with its graphic leaves, it finds its place around a contemporary house.

Belonging to family of Asterids, a genus Helenium includes 40В species of annuals, biennials and perennials native to wet meadows, marshes and riverbanks of North America, often in areas flooded in spring. Very few of them are found in cultivation, which have given rise to more than 70В hybrids and.

Good to knowВ: endemic in North America, it is in Europe that henya has been successful. Breeders, mostly German and English, have expanded the color palette and reduced the size of wild plants, before exporting them to North America!

Most of the plants that are found in cultivation form a basal tuft of deciduous, slightly toothed, downward-sloping leaves, of a clear green color, from which sprouts emerge. rods with a height of 0.60 Г 1.50В m. The stems, quite rigid, are branched in their upper part where bloom, from summer until frost, flower heads appreciated by bees and butterflies, composed A prominent yellow or brown disc surrounded by radiant florets in warm colors, yellow, bronze, orange or red. This close relative of sunflower and rudbeckia is distinguished by its much more rounded central cone, green, yellow or brown, and by the toothed end of its rays, which form three rounded points.

Flowering lasts a very long time, from 6 to 10B weeks between the end of June and October. Early hollies bloom all summer, while late ones begin to bloom in the summer to blossom in the fall.

In its natural habitat, the plant grows in moist, clayey areas, and always in full sun. Yes she likes the grounds a little fresh, it supports however a temporary drought and is easily cultivated in any good garden soil which is not too dry. It can tolerate partial shade, but the stems will then be less rigid and will probably need to be staked.

Helleny will be in its place in flowerbeds or sunny beds, in the company of other perennialsВ: hémérocalle, liatris, rudbeckia, kniphofia, dahlia… Or install it in a country garden, in the company of grasses, daisy, eupatory, aster, spurge

Very hardy, henya can be grown in all regions. In addition, it behaves well by the sea. It is also a good flower to cut.

AttentionВ : contact with leaves can cause skin allergies. The whole plant can cause digestive disturbances if ingested.


You don't have to live in France to grow state wildflowers. Learning to propagate coreopsy is easy, even for a novice. You can root tick seeds from seeds, cuttings and divisions, and all the methods are quick and easy.

The best environment for propagation would be in a greenhouse, as it is suitable for starting vulnerable seeds or growing mother plants for cuttings and divisions. Like all plants, newly propagated plants are still establishing themselves, so you need to get them vigorous enough to be transplanted under fluctuating outdoor conditions.
