Lynn, I would just leave it there seeing as the rain is pretty much abated for the summer. You might want to mark it with a stake after you cut it down, especially if you do want to move it. Best to move in the fall.
Isn't it fun gardening here in the Willamette Valley. I need to quick lurking on the semp/sedum forums and get around to posting a few of my pics. I have some nice stuff. Not like you though with your huge collection. But hey! I have a couple hundred lilies, does that count?
