I visit Van Wade's gardens regularly. It is most pleasant.
I buy hosta from Q and Z Nursery in Illinois, and I trade with others.
Late May through the end of June, I sell potted hostas from my gardens, less than $10 a pot.
Last summer I sold more than 300 pots.
I also hybridize hostas. I have never registered them, and in the hosta world, that is not as important as in the daylily world.
I just started to collect daylilies, and of course, I will be hybridizing and selling them as well. Eventually, I will sell plants on line. Check out my list on ATP.
