The Dahlia That Won't Die
I can't even remember the name of this one. I keep digging it out, and it keeps coming back. I keep digging it out because it overwhelms a 'Pure Poetry' rose and Clematis 'Asao', which is struggling. When the Dahlia first starts blooming I like it, but then it proceeds to overwhelm everything around it, flops all over, and gets itself mildewy and chewed. If I was more organized I would move it to another spot, which come to think of it there's a good place down by the pergola, but perhaps down there it would start overwhelming Clematis 'Polish Spirit', and I'd be digging it out of two spots every year instead of one.
If it was a Dahlia I particularly adored, I probably couldn't keep it alive no matter what I did.
