What are these and is it worth keeping the bulbs that didn't flower?
I can't find these in any of my books so hope someone knows what they are. The foliage comes up several weeks before they flower and it looks really messy. Then suddenly these lovely star shaped flowers come out but only when it's sunny.
I intend to dig some up once they've finished flowering because there are just way too many, but is it worth keeping any that didn't flower? Also, because the leaves just look really untidy I'd like to trim them back after flowering, but I assume I should really leave them for a while?
