My friend has always grown penstemmon plants, and every year I have just
found out she bins them, and puts new ones in, is she correct? or can I
dig up the ones she is now planning to bin, and plant in my garden....
Worth a try. IME some come through the winter well others don't.
Could take cuttings and root them over winter on a windowsill or in a frost
free greenhouse (don't water much).
