Country of Origin: Brazil (ParanŠ to Santa Catarina) (endemic)
Habitat: example of convergent evolution w/ Agave
Description: stemless, herbaceous, rhizomatous perennials with thck, rigid, spiny leaves (about 30 when mature) in a rosette, central erect, outer recurved with lines of whitish scales; when fully mature, about 8 inches long, 18 inches high; flowers yellow, many in a spike about 12 inches, shorter than the sharp pointed bracts.
Culture: Dyckias should be grown like succulents - in bright light and well-drained soil. While they are drought-tolerant, they do like water, especially during summer months. In fact, one (D. brevifolia) grows on rocks that are submerged during the rainy season. They tend to develop huge root systems, so give them plenty of pot space, or, climate permitting, grow them in the ground.
