| More to learn | Traditionally, the origination of star cactus comes from Hidalgo, and Starr Countries in Southern Texas region, Cameron, Tamaulipas in Mexico, and the border states of Nuevo Leon. Now, Star cactus plants generally grow in semi-protected areas under brush. Since this cactus is spineless, partial shading from surrounding brush may be important in providing a favorable microclimate for growth. Successful seedlings tend to be found in close proximity to shrubs, trees, other cacti, or rocks. However, plants do occur out in more open areas. |
