Habitat Requirements

Star cactus occurs among sparse, low shrubs, grasses and halophytic (salt tolerant) plants on xeric upland sites. Soils are usually gravelly clays or loams, and typically contain high levels of gypsum, salt or other alkaline minerals.

Food Habits

In the wild, star cactus is restricted to xeric sites that usually have high levels of salt, gypsum or other minerals.

Movement / Home Range

Star cactus is known from Coahuila, Nuevo Leon and Tamaulipas, Mexico as well as in Zapata, Jim Hogg, Starr and western Hidalgo counties, Texas.

Reproductive Strategy

Strong (2007) estimates that star cactus plants reach a reproductive size after 19 years. She determined that the flowers are self-incompatible, requiring out-crossing by pollen transfer from a different individual. She observed numerous insects visiting open flowers of star cactus, including 1 species of ant, 6 beetle species, 12 bee species and 1 species of bee fly; a small bee, Macrotera lobata, appears to be an effective pollinator. Fruits contained an average of 55 seeds. Strong, A. 2007. Astrophytum asterias: A Review. Oral presentation at Texas Plant Conservation Conference, Lady Bird Johnson Wildflower Center, Austin, Texas, September 19 21, 2007.

Other

The spineless, dull olive-green, dome-shaped stems of star cactus, up to 6 inches in diameter, are divided into eight radially-symmetrical segments, each adorned with tufts of white hairs.
