Cleistocactus baumannii SEEDS

Cleistocactus baumannii seeds grow into Baumann's cleistocactus — an arching to erect, slender columnar cactus native to the seasonally dry tropical biome of Bolivia to Uruguay. The genus Cleistocactus means 'closed cactus' (from Greek kleistos = closed), referring to the tubular flowers that do not open widely, being pollinated by hummingbirds. Named after Constantin Baumann (1809–1884), a nurseryman at the Baumann Bros. nursery in Bollwiller, Alsace. Produces slender, erect to arching, branching stems to 2 m; 16–17 ribs; brownish-yellow spines; distinctively S-shaped, narrow, orange-red to crimson tubular flowers 5–7 cm, strongly inclined upwards. Cold-tolerant. Family Cactaceae.

Full sun; very well-drained, rocky or sandy soils; drought-tolerant; cold-tolerant; Bolivia–Uruguay conditions.
