An interesting Mexican lithophytic species from Oaxaca where it lives in very arid conditions on rock outcrops. The leaves are very stiff, almost needle-like, about 18 inches long. The habit is like that of Till. juncea, but the foliage is much more robust. Related to T. rodrigueziana.

This species is similar in some ways to Til. gurreroensis, but is smaller, with larger, almost fuzzy, trichomes. The inflorescence is simple, a pink spike with deep blue flowers. (The photo is lighter than actual) Discovered by Renate Ehlers, and named by her for her husband and collecting partner, Klaus. A rare gem.

From Argentina, grows as a saxicole on exposed rock or epiphytically in scrubby thorn bush, almost always forming large clusters. This caulescent species has a rigid stem and short, stiff leaves, all a dark grayish color, and bears large and very fragrant, white flowers.

A notably easy species to cultivate, tolerating a variety of conditions and light levels. Prefers to be kept bright, airy and on the dry side

A beauty that grows in long caulescent clusters, with wide, stiff, silvery-white leaves. The inflorescence is a simple thin red spike. Native to central Mexico. Can be cultivated in a basket, mounted or hanging from a wire or string. Likes bright light and good air circulation.

A small lithophytic, clustering plant to about 2 inches, with short, stiff and rather succulent, dark gray leaves. Widely flaring, half inch pink flowers are borne on a short scape in small clusters. We’ve seen grapefruit sized clusters of this species growing on rocky cliffs in Bolivia, covered with pink flowers. In cultivation it enjoys growing mounted and kept in bright light with good air circulation. Allow to dry quickly after watering.
