I'd never seen anything like them before. I've seen a lot of blooming cacti around here but this one was special. The petals truly look like bird feathers. So instead of stopping to smell the roses. I stopped to photograph a cactus. It may not have been as fragrant but it was just as rewarding.
It also made me wonder if brides ever use cactus flowers in their bouquets and arrangements. I have no idea if the flowers are long lasting or wither quickly. If they do last they would be pretty show stopping to use in a wedding.
