nan,
thanks so much for this lead. VERY helpful. i hope you cut and post it into the perennials forum;I'm sure they'd appreciate it over there.
best,
mindy

BTW, someone in another thread mentioned that they use the 'clip this post' function on the forums, to say information they may be looking for later. I had not used that until then, but now find I am using it a lot to keep track of posts I want to remember. This would be one of those posts :-)

DTD great article on this topic! This year I need this information as this is my first year with these plants. Given how cold it got last night (to 39 degrees in my garden) unfortunately I think the frosts will come early this year so we've got to be prepared.

When I visited Steve Silk's garden on open days this past Sunday I heard a rumor that he has an article coming out in the next issue of Fine Gardening that will be dealing with this exact topic. It would be nice if the info in that complemented the info over at the Avant site.
