If you can wait a couple months, I have Attraction, Bi-Color, Black Night, Pink Delight, Royal Red, White Profussion, Nanho Purple, and Honeycomb. My butterfly bushes are still at ground level for the year. I cut them down every year. I wouldn't suggest Honeycomb for your zone though and you may have to check on the rest. I do not know which ones are hardy to zone 4, I just know Honeycomb is boarderline in my zone. I do not need any more butterfly bushes though and I have no idea how to make butterfly cush cuttings.

you know one of my traders pointed out that I didn't mention how large these plants are. They are 2 year old suckers and the height is anywhere from as high as my knee, to as high as my thigh, lol. How"s that for a description. I have to tape 2 of the priorty boxes together to mail them out. Thanks for letting me update and thank to everyone for the wonderful trades! Sue

If it were my plant and I wanted to save it, I'd wait till after the last frost and plant it like any other shrub, using the newer outside shoots and discarding the largest old trunks. You'll have a beautiful bush. I'd call the coop extension or an experienced landscaper for info about winter transplanting. With balled Christmas trees I know they plant the ball in a pre-dug hole for the winter to be transplanted later. Good luck! It's nice to have a plant with a memory story.

70-100 days to root. Never had that happen to me. I take a two inch cutting, no heel, with two nodes, with both mature leaves cut in half. I root in a 2 part peat, 1 part medium coarse perlit, and 1 part fine fir bark. Rooting hormone is applied lightly, with the soil being moist before insertion. I fill plug trays, hexagonal 90, with the cuttings for maximum spacing. Misting is carried out every 45-60 minutes, with humidity kept at a constant. Neem oil is sprayed every week, to control botrytis and dampening off with the present humidity. Fetilizing is only applied once a week after root presentation.I can have a finished trade gallon container in less than 3 months, with flower buds emerging into color.
