I was looking for pugster blue but couldn't find it..but did find blue chip jr at local lowes. So happy that I have all colors covered for now. Have the bicolor too..lol :) Meanwhile my abe darby is getting ready to bloom. Same plant but different color buds.Graham thomas in full bloom mode Tom I got to smell oklahoma rose at lowes and its stunning. Only if I had the place for another red rose it would have come home with me.

Hey Tom, I know I have a pretty rare one I got from a friend in which his visited I think was Columbia from the forest, then I have a few other pretty cool ones. I will take pics and you can see the leaves. I would love that! I am rooting some now...Who knows, maybe one of my mother plants will die and you could carry on with it and have back up just as I would for you. Thanks buddy Tom here is my e-mail when you get a chance and I can provide my address and such. I can send you cuttings as soon as yesterday! mikerno_1@yahoo.com

I had a "Butterfly Heaven" for several years before the polar vortex nearly killed it. It did produce several seedlings, a couple of which I transplanted to a well drained spot in the yard, and they have come back strong every year since then. I also see some larger BB's on other properties in my area that have survived long term (including through the polar vortex years). The hardiness of different varieties does vary. I'm guessing that a few of the older varieties like "Black Knight", "Pink Delight", and "White Profusion" are hardier than average, and there is a variety called "Windy Hill" (no experience with it myself) that was selected for superior hardiness. Some of the newer varieties apparently have good hardiness as well. Even though my buddleias produce seedlings on a fairly regular basis, they're never going to become invasive in this climate.

in my ground freeze s5 mi ... the colder the winter.. the further down they died back.. until one very bad winter.. they dont come back.. z5 is almost half the US.. and tells us nothing.. big city name will help .. and whether you are in the city or rural might also matter.. in spring.. the soil has to warm.. down into the root mass of a plant.. for it to come active.. and day temps are not relevant.. its how cold it gets at night .. which dictate how warmth int he soil builds.. i probably wouldnt expect to see them until may some time.. [e.g. to day its supposed to be above 80..... and tonight.. down in the mid 30s.. whats that all about.. lol.. MI in spring ...] i eventually gave up on them.. they were ok when i was in suburban metro detroit.. they died too fast in rural mi.. winter is just colder out here.. and they didnt like the sand out here ... ken
