Have many natives and others to trade.
See my page for possibilities.
I'll keep an eye out for these. I think there are some growing in the empty lots here.
Look for a Nursery in the area that carries the "American Beauties" collection it should be avail there. Picked up a couple gal pots jampacked with plants $9.99 ea. Divided each pot into quarters. Probably could have whacked each piece again.
They are spreading nicely.
Hope this helps.
