Good morning, Betsy.
Have you considered buying from members? Every spring I offer over fifty cultivars including the hosta of the year. Prices are very reasonable for quality plants. Take a look at my list, and remember that I will list which ones will be for sale.
In the past I bought from QandZ nurseries, but they are no longer selling hostas. If I want a hosta, but I am not going to buy large quantities, I will buy from Wade and Gatton or Plants Delight.
