I bought a 3 inch potted thumb cactus about 2 years ago and planted it in a bowl. It grew to about 8 inches then slowly fell over sideway...Read Mores and continued to grow sideways. I planted it straight up in my cactus garden last week and it is upright but bending a little in the middle. I'm propping it up with two sticks.

Has a distinctive brilliant pink halo of flowers that make a ring, 2-3 flowers thick, around the circumference usually just an inch or two from the growing tip of the cactus in late spring.
