Thanks everyone. It's such a relief to see some of them blooming -- even though I'm still finding evidence of rot here and there.
Greg -- you are so right about DofS needing to get established. I think that's probably true for many of them -- we shouldn't judge them the first year, but give them a year or two to show us what they're about!!
And yes -- taffeta is a fabric like silk -- but is sort of stiff, not drapey. It was used a lot in days gone by for dressy dresses because it wanted to flare out and a net slip underneath would support the fabric and make it do just that. Boy -- there's a trip down Memory Lane.
