This is a “thimble” cactus flower, currently blooming in a pot on the patio. This cactus variety is native to central Mexico. The cactus consists of many little round buds, each of which has clusters of interlaced white spines, which are quite stiff and sharp. If left on the open ground, the cactus will spread to form large mats like a ground cover.
This little cactus produces satiny, creamy yellow flowers. It likes bright light and warm temperatures, although it will tolerate short duration temperatures down to as low as 20 degrees F. Click on the image above to enlarge.
