Globular to cylindrical plant. 13 ribs - tuberculated; tubercles having furrows. 1 hooked central spine (yellowish with red tip), 7 to 10 radial spines (light colored).

The plant's central spine, which is shaped like a tiny fishhook, is proportionately longer than the radial spines. Our plant was purchased at DesertPlants and produced some pretty maroon blooms before freezing to death. RIP.

This astrophytum requires less water than other species, doesn't tolerate humidity, and prefers to be planted in a deep pot. SRA

The Goat's Horn is named for the characteristic shape of its long, curled and flattened spines. The spines are very fragile, so, plant should be handled with care. The skin of this 8-ribbed cactus is covered with small white flecks: a characteristic of the genus. It will eventually produce a tapered column around 10 inches in height. Our plant was purchased in Tucson. RIP.

The star-shaped body of this cactus epitomizes the Astrophytum (star-plant) genus. The plant is covered with a myriad of with countless white spots called flecking. Eventually reaching 16 inches tall, this easy to care for, 5-ribbed cactus is an excellent bloomer. Volunteer seedlings have germinated from our plant.

This nudum variety of Astrophytum myriostigma lacks the white spots normally present in the species. You could say that it is nude. It too is a 5-ribbed plant that blooms yellow. Unlike our white-spotted plant, this plant has not produced volunteer seedlings for us.

This is a plant with many accolades. Named for Andrew Carnegie, this cactus is the classic symbol of the American West. Saguaro National Park in Arizona was created to protect this somewhat rare Sonoran desert plant. Its white flower is Arizona's state flower. The uses for this cactus are numerous. It is a very slow growing and long-lived cactus: consider its lifespan. At 10 years it has grown 6 inches. Blooms occur on the plant around 40 years. Branches appear around 75 years. Mature specimens often greater than 50 feet high are aged 200+ years old. Our plant was grown from seed.

The long white hairs are actually long spines that benefit the plant by reducing sun exposure and by trapping a layer of air next to the cactus body. This helps to cool the plant in the summer and keep it warm in the winter. Our plant was purchased at the Tanque Verde Greenhouse, Tucson, AZ.

This cactus has white blooms that open at night. One of the first cactuses that I started out with as a boy.

Received this plant from Leslie. Three or four cuttings salvaged from a plant left out in the cold.
