Well, having made a mistake with Ornithogalum umbellatum, I would
like to compound it :-)

Basically, I am looking for other bulbs that might naturalise in
grass and flower immediately after the main spring ones. The obvious
candidates are bluebells, but I had to get rid of them on the grounds
of thuggery. I can find plenty that flower a bit later, together
with snake's head fritillaries, but not in the April slot.

I don't want ones with broad leaves because of the effects on the
grass - daffodils are just about tolerable, but tulips and Allium
ursinum would not be.

Any ideas?

Regards,
Nick Maclaren.
