I have done some research on these and you can root from cutting supposedly very easily they have some sort of aspirin like tendency in them which is used a lot when using rooting hormone, some people even use a cutting in water along whatever they are already rooting to help developed roots on other plants and fall is the time to do this, I have plenty of weeping willow cuttings If interested.

I am looking for cuttings or rooted cuttings, of the weeping pussy willow, blue leaf willow, and the one called Nicki.............. can't find the fullname. I have rooted corkscrew willow (generic)to exchange. Vangy likes to play in the dirt zone 5 SW Michigan

Have willow cuttings this spring -- how long do you need? Will three-feet do it? And how many would you like? I'd love some of your iris -- preferably not yellow or purple -- white, white & and any other color are my favorite, blue, purple with yellow -- really any you'd like to thin out. Let's stay in touch, my willow is doing great, was a gift 20+ years ago (from a nursery) and is nearly 30-feet high. I'm also in zone 3.

this is not a trading forum .. but instead of reporting you.. i will just tell you .... they root in a few weeks.. if you have a local one.. just get some 8 inch cuttings ... either stick them straight int he ground.. of in water until you just see roots.. then pot up ... google it.... if you dont believe me .... ken
