I live in Vermillion, SD, zone 4. I would like to hear from anyone who has had
experience growing Austrees. These are supposedly sterile male clones of Salix
Matsudana X alba, and are sold by Rocky Mountain Austree in Colorad Springs,
CO. I would like to know if they are reliably winter hardy in similar
climates, and if they are likely to get out of control and become a threat to
native species. I am considering planting some for bank stabilization along
the Vermillion River, whose water level fluctuates a great deal over the course
of a year.
Thank you for any advice you can give.
