For much of the year they are simply clumps of green leaves. Then in winter they die back and disappear completely. But when they re-appear they make sure they are noticed.
We began (a few years ago) with one plant and each year the bulbs multiply. It wouldn't be possible to count how many we have now. Many bulbs have been given away as well and hopefully will be putting on the same show in other gardens at the moment.
These plants receive no attention - except when they flower. They survive on rain water only and reward us year after year with a great display.
Gradually we are acquiring more as the seeds germinate. The clumps can be dug up and divided but I'm in no hurry. I just keep an eye out for any volunteer plants that come up and transplant them to where I want a new clump.
Some people have fairies at the bottom of their garden. I have hippies.
