Something unusual?

I was always told not to let rhubarb flower. Affects the quality of the fruit but

1. I don't really like rhubarb - I planted it for my ex partner :-(
2. I've been so busy the poor garden has been a little neglected so the rhubarb took advantage of me being a little slow and there it was.

I think they are rather pretty in an unblousy sort of way. May try drying them for my sis in law who is a flower arranger??
