Hi Larry! We grow a lot of different species, including Dogwoods. The nursery is very busy, we never have time to grow grow from seed. (Although this may change, folks with 1 gallon plants begging us to buy young trees and shrubs).
I grow from seed for this hobby alone lol.
Bruce Banner #3, Cheese and Afghan hash plant just sprouted.
My wife would be unhappy if I went large on my hobby. (Couple lbs slightly larger than a hobby ha!) Good luck to you Larry and enjoy my Birthday holiday!
