Cactus Cousins and Their Flowers

Star Cactus Bishop’s Cap

Two of my favorite cacti were in bloom today; the Star cactus flower on the left is the third flower that has opened this summer on my astrophytum ornatum. The flowers on the right are on my old reliable Bishop’s Cap cactus, astrophytum myriostigma. Both cacti are in the genus astrophytum of which there are five major species and a bucketload of variations.

The latter cactus above gets clusters of flowers on a monthly basis it seems, all spring summer and fall. The other flower is only the third one to open on that cactus, but there are more buds and I expect others to open as the summer progresses. Click on either image to enlarge.
