Trying to identify seeds that I planted.

this is Liatris

Thank you Bobski2. So that's one of the bulbs I planted (not seeds) and wondered where they were!

you can get them in white too.

full name Liatris spicata and the white has the additional name 'alba'.
they are a type of corm. they are fantastic and good doers.

I'm really pleased with them, and so glad they finally appeared. Only thing missing now from the bulbs I planted is Brodinea - that might turn up too one day.
