Help identify this flower

Peter, I haven't a clue but wanted to point out to you that most experts, even those with encyclopedic knowledge and the memory of an elephant can't remember every flower...so take heart...

If you're still interested, Peter, I'd almost certainly say Chionodoxa, owing to the flower, leaf and date. Spring-flowering, autumn-planted bulbs, readily available here, should you wish to plant up a container or area in the garden as a "reminder" of Tokyo. :-)

Lori - sorry, I must've missed your comment - I don't think I'd even try to remember everything but I'm slowly learning :o)

David - Thanks for that, maybe next year. I've got Snowdrops, Crocuses and Alliums bulbs planted for next year. Some in the lawn so I'm taking up valuable veg space :o)

Peter, there'll still be time after the flowers have gone to dig up the lawn,move the bulbs, and have the veggies :-0)

Digging up the lawn is a delicate matter at the moment - I've mentioned moving the path in a foot or two so I'd have more room for veg. Plans were rejected by higher powers :o)

Peter - :-(
