Thanks Momofmany's husband! I will definately yank those!
For some reason I just feel "bad" about yanking some of them if I am not sure - when I was out earlier I stepped on one of my flowers - I apologized to it.
I think I am going to let the purple flowers grow again this year - I someone also remember these tall yellow flowers growing in the same area. I am afraid when we moved here there was so much going on with my job moving and us moving do a different state- that I didn't pay that close attention to what sprung up.
I do beleive I will leave a few of the Astilbe where they are, but I will relocate a few - there are a few too many in the current area for my "vision" of the area.
Goodness gracious - it is going to take me all year to get only about 1/2 my yard in shape... there is something to say for the tiny yard I used to have.
