Origin and Habitat: Mountains of Minas Gerais (Brazil, Southern America) where it often grows at very high altitudes.
Habitat: In nature it grows in cracks between rocks or on the rocks themselves, usually where there is a very high degree of atmospheric moisture, which compensates for the fact the soil is perfectly drained. In its natural habitat the plant frequently grows among lichens, which may even cover it.

Description: Uebelmannia meninensisSN|14307]]SN|14307]] is a short columnar usually solitary cactus. The var. rubra differs from the standard species only for its more dark-purple body.
Stem: Globular when young, later becoming elongated and cylindrical, greyish-green or reddish-green (rubra), 10 cm wide, 45-50 cm tall (In cultivation the colour of the plants depends on sun exposure, the plants grown in shadow are greener, wile the ones in full sun take a bright purple colour)
Ribs: When fully mature it has up to 40 prominent markedly tuberculate, but initially it has considerably fewer.
Tubercles: The tubercles protrude about 8 mm, are separated by transverse grooves and have apical areoles.
Areoles: Close set.
Central spines: 2 or 3, 2 cm long, pointing downward except for the upper one, which is shorter.
Radial spines: Absent.
Flowers: Diurnal yellow. They are up to 2-4 cm long , 2-4 cm in diameter.
Blooming season: Flowers come sporadically from early summer to late summer.
Fruit: Inconspicuous, dark red and globular.

Cultivation and Propagation: This tropical genus, which is hardly ever cultivated except in very specialized collections, loves warm moist, humid conditions and mist spraying is a must in summer. Water regularly during the growing season (rain water is highly recommended) and use a very draining low pH mineral potting substrate (if possible not limestone) otherwise growth will stop altogether. At the onset of winter, do not water. Uebelmannias need heat all year round and extra winter heat, minimum 10° C 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 full sun position and possibly afternoon shade in summer. If you can place it so that this occurs the plant will be much happier.
Propagation: 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 the ideal.
