Astrophytum ornatum
Astrophytum is not a large genus, but it is very popular with cactus collectors and widely grown around the world. Astrophytum ornatum is the largest species, attaining a height of up to a meter or more in cultivation, and reportedly sometimes reaching more than twice this height in the wild. The flecks of white on the plant body are seen on various species and add an attractive touch. The large flowers come in multiple flushes through the summer and fall months, and they are initially yellow, but they often change to pink as they age (thus, the flower on the right in the photo is the one that opened first, and has now tuned pink, while the newer flower on the left is still yellow). Astrophytum ornatum occurs in several states in east-central Mexico.
