Native Button Cacti of Texas - Epithelantha micromeres

Native Button Cacti...with it's fruit.  Actually the fruit is more colorful than the tiny flowers.  The flowers are hard to see and are a pale pink.

They like to hide among the grey rocks, but the red fruit gives away their hiding place .  The cacti themselves are a pale grey and hard to find.

Small Flowered Button Cactus

Last year I found this little cactus with the red seed pods.  I kept a close watch, but could never see the blooms. 
Last week I was watering and looking over the plants to see what was growing and what was not.  I couldn't believe it....tiny, tiny pale pink blooms...no wonder I had missed the blooms last year.  They were almost to small to see.
