I sell common but mainly specialize in rare, streaked hostas for hybridizing. Have many thousands of hostas to buy and look at. I also ship all over the USA and possibly some foreign countries.
I also do the Hostalibrary.org which has 13,000 photos of 5,500 different hostas. I run an auction and forum there as well. This website is non-commercial otherwise, just for information. Used by much of the world for identification.
