Flowers beginning with B

I always try to grow busy lizzies and begonias for bedding, with varying degrees of success.  Must try harder. 

I pick up a tray of cheapo busy lizzies/begonias for a couple of hanging baskets - their tiny seeds are way too fiddly for me.
The tuberous Begonias are well worth growing though - come back year after year here with no overwintering needed. There's one growing on the edge of a patch of brambles - I've no idea how it got there as its the sort of daft place that even I wouldn't have chosen.

Plenty of bluebells here too but not all are English ones - there are some of those Spanish invaders amongst them - that I try to pull up when I spot them but they still seem to appear the next year.
