Yes you are right about that Bob, I have visited PPP.com and they are a good source for the hard to find. I have several liners right now because that was the only thing I could afford with certain varieties. Last summer when Country Boy's had the end of summer sale I got at least 30 liners for two or three dollars a piece and they have done well. Also Country Boy's is good company. They had a little bad luck last summer with a bad storm that came through.
(oh, I called them liners but they were really one year plants, my bad.
I did not know they had Heucherella also. How are the shipping fees? This would be a good way to add some companion plants to my Hosta Garden. Whoohoo!
