A year or so ago I bought a little cactus that was in flower and put it right in the window and did my best to neglect it in the hope it might flower again. Well it has!! Just look at this -
I have a Haworthia as well in a pretty multi coloured pot - it's actually a tea light holder but after much hunting, I found a plant pot that just rests in the top.
They're so tiny and delicate and I can't imagine what type of insect pollinates it.
I have a mother-in-laws tongue as well that has been with me for about 10 years now. His name is Spike. He did flower once and they were gorgeous little star shaped flowers that didn't open until late afternoon and come morning, they had closed and withered. Clearly designed to attract night pollinators. I have some photos somewhere but they're on the old laptop/hard-drive - I really must copy them across...
