Uebelmannia

Rare form with golden-yellow spines resembling those of Eriocactus, contrasting sharply with black-spined varieties. It grows on quartz outcrops in Brazil (Minas Gerais), between 700–1,100 m, among rocks.

U. buiningii characterized by a dark puple-red body is the most diminutive and also the most floriferous of the genus. It is a very pretty plant but tricky to cultivate and almost always grown grafted onto columnar cacti. It is very rare. OWN ROOT !!!!

An extremely rare species growing on pure quartz gravel with highly acidic pH. The var. rubra differs from the standard form by its darker body, showing rich reddish-purple tones.

This is the population of Uebelmannia found in the highest elevation locality of the genus ( 1415 m)

This is the southernmost population of Uebelmannia growing at an altitude of 1220mThis is the southernmost population of Uebelmannia growing at an altitude of 1220m

Solitary globular cactus with stems shifting from green to purple, topped by a woolly apex. Areoles are so densely packed they appear as near-continuous felt-like lines along the ribs. Honey-yellow, amber, or orange-brown spines.

In their juvenile and smaller state, the plants are dark purple-red; however, as they mature and are exposed to full sunlight, they transition to a green color.

A geometric wonder with leathery green to bronze reptilian skin. Its woolly gray crown offsets amber-reddish juvenile spines that mature to graphite, all comb-aligned with mathematical precision. Nature's sculpture at its most symmetrical.

The var. multicostata represents a local form of Uebelmannia pectinifera distinguished by its higher rib count. While typical U. pectinifera develops 15-18 ribs, this variety consistently produces 20 or more.

Questa varietà si distingue per il maggior numero di costolature (20 o più), contro le 15-18 della forma tipica. As the plant matures, it takes on a greyish-purple coloration. Absolutely stunning!
