A nursery near me has several "Black Pussywillows" in 3 gal pots that
they're going to let go cheap ... I've never heard of these for
bonsai, so i didn't leap on them. BRBR

The botanical name is Salix gracilidelineata 'Melanostachys.' It is hardy to
Zone 4 or 5. They have beautiful red flowers in February or March. I have heard
of it being used for bonsai. Give it a try.
