Below is the detailed description of the Uebelmania pectinifera species. You can find here answer on many questions about this species.

Scientific Name: Uebelmannia pectinifera Buining 1967

Origin: Brazil ( mountain of Minas Gerais ).

It is only known from one location, north east of Diamantina , mountain of Minas Gerais , in Brazil . (cactus-art.biz)

Conservation Status: Listed in CITES Appendix 1

Etymology: The species name "pectinifera" comes from the Latin for "bearing combs".

Recommended Temperature Zone: USDA: 10b-12

This is one of the most striking and recognisable Uebemannia with a green to deep purple or reddish-brown, firm, almost lizard-skin textured 'skin' and spines on vertical ribs.

Description: Solitary cactus, 4 to 6 inches wide (10- 15 cm ), 20 inches tall ( 50 cm ) 15 to 18 prominent ribs close set areoles 1 to 4 central spines, up to 0.6 inch long ( 1.5 cm ), in the classical look, the spines are straight and give a comb-like effect.

Stem: Solitary cactus 50(-80)cm tall.
Stem: Although usually globular or slightly elongated in cultivation, it is reported to grow to as much as 800mm tall and 10- 15 cm wide. It is dark reddish-green to reddish-brown, with off-white scales. (In cultivation the colour of the plants depends on sun exposure, the plants grown in shadow are green with white stripes, while the ones in full sun take on a dark frost brown or purple colour)

Flowers: Diurnal, funnel-shaped greenish yellow. They are 15 mm long, 12 mm in diameter.

Blooming Habits: The diurnal yellow flowers come sporadically. They are 0.6 inch long ( 15 mm ), 0.5 inch in diameter ( 12 mm ).

Flowers come sporadically from Early spring to Late Summer (cactus-art.biz)

Habitat: The plants are found growing in dry savanna and rocky areas in rock cracks or in pockets or small flat areas of organic leaf mould and sand found among rocks at about 1000m altitude. It is threatened by habitat loss. U. pectinifera is more common in collections than it is in habitat

Sun Exposure: Full sun, possibly afternoon shade in summer in very hot climates

Water Needs: Regular water do not overwater. Root prone if kept cold in winter, sometimes grafted to eliminate this problem. Enjoys humid air.

Cultivation: This tropical cactus loves warm moist, humid conditions and mist spraying is a must in summer. Water regularly during the growing season and use a very draining mineral potting substrate. At the onset of winter, do not water. Uebelmannias need heat all year round and extra winter heat, minimum 10C is best. Avoid any frost. Keep cool in summer. This plant prove to be root prone if kept too cold in winter. To help stop this , a good deep collar of pumice or lava grit is an excellent idea. It prefers a position in full sun , a nd possibly afternoon shade in summer. If you can place it so that this occurs , the plant will be much happier.

Min Temperature 60°F ( 15°C )

Frost Tolerance: Keep above 40°F ( 4°C ) in winter, avoid any frost

Heat Tolerance: Keep cool in summer

Propagation Methods: From seed winter sow in vented containers, coldframe or unheated greenhouse
From seed direct sow after last frost. Seeds, but plants are often grafted , making them easier to grow, particularly through the winter. If possible using a rootstock that is more hardy than the Uebelmannia is ideal.

This is one of the most striking and recognisable Uebemannia with a green to deep purple or reddish-brown, firm, almost lizard-skin textured 'skin' and spines on vertical ribs. The Uebelmannia pectiniferaand all the other plants belonging to the Uebelmannia pectinifera complex are very variable in habitat, it has three recognized subspecies, but a multitude of different forms exist, where each form is linked to others by populations of plants with intermediate characteristics


How to Grow Uebelmannia Cacti Indoors

The Spruce / Anastasia Tretiak

Though often used to describe a singular type of cactus, the name Uebelmannia actually refers to an entire unusual genus of cacti. Composed of only three species, Uebelmannia was only brought into the mainstream trade from their native South America during the mid-sixties, and at the time was unlike any cactus ever seen. They are unique in appearance and can be truly impressive, featuring distinct vertical ribs covered in areoles in white, black, or gold. They're usually cylindrical, and their skin has an odd, waxy look to it. Together, the effect is truly one-of-a-kind among cacti.

Uebelmannia cacti are beloved by serious collectors, especially U. pectinifera, which has black spines, a purple body, and can grow up to 12 inches tall under perfect conditions. Their beauty, however, is matched by their rarity and their difficulty. These cacti are very hard to track down and can be expensive in cultivation, they have specific and difficult requirements that can make them a real challenge to grow.

For that reason, these cacti are best left to experienced growers. If you do choose to try your hand at growing Uebelmannia cacti, you can tend to them year-round indoors, where they'll grow slowly, eventually reaching up to 3 feet over time when given the proper conditions.

Gardeners' Notes:

Here all this time i thought i had a burned Parodia sp. and it's this cacti instead. Survived the freezing temps of 07 with no damage.I prefer the look of the greenhouse grown original green with white stripes, over the frost brown color it shows in full sun. I have to wonder if it grows in full sun or shaded by trees in it's habitat?.

Even though this is a tropical cactus and isn't supposed to handle my climate, I have had one outdoors for about 8 years and it gets frosted every year. Yeah, it doesn't look perfect, but it doesn't take much to scar this delicate species. It is one of the most beautiful cactus species in my opinion, having a dark green, firm, almost lizard-skin textured 'skin', nice angularity to it's overall spherical shape and linear arrays of not-too-viscious black spines down it's sides on a white fluffy background. It's a striking cactus and most people seem to notice it before all others in the garden. It's a Brazilian native.
