Geranium macrorrhizum competitiveness
I am wondering if G. macrorrhizum will choke out everything it comes in contact with... that is, if it's planted with spring bulbs or ephemerals, or even some other tall perennials, can they all get along together? Or will it end up being only the geranium? I haven't grown it before, so I'm looking for some guidance from more experienced growers.
What do you grow it with, if anything, in a mixed bed? Or is it strictly a ground cover?
