I’ve managed to get two blooms out of my cactus this summer, a personal best. I say I did it, but really I did nothing much apart from putting them in a hot and sunny spot with occasional watering and then noticing the blooms were there and photographing them. And here are the photos!
These flowers are so lovely but only last about 2 days then they fall off. I caught the first one in a semi-bloomed state one day, then checked back the next day for the full flower. The following day it was already spent. What a pretty little display while it lasts, though.
