Crystalview,
with Clint. But I don't try to deadhead individual blooms, except at the beginning of the season. Later, I use a grass shears and cut the stems down to the foliage. It will look ratty for a little while, but should rebloom.
Clint, I'm glad that you mentioned that the newer ones don't seem to be long lived. I thought maybe it was just me. As I've had some problems with that bed, starting with loss a huge oak tree that provided much needed shade. Part of it fell onto the bed and stayed there for at least a month.
I'vehad Jethro Tull for 2 or 3 years, but I don't see it. I did have the double flowered ones, but put down a thick mulch for a couple of years, so it didn't get to reseed. I also had a couple of the Starlights, which I don't see. Route 66, I'm sure is still here and a thread leaf plant, I think Sienna Sunset has come back for about 4 years, so I'm sure it's a keeper.
It may be a little too wet here for coreopsis, so I may need to add some grit when I plant them in the future. If anyone has any Moonbeam that they'd like to share, please t-mail me.
