I’m in NE Oklahoma. Zone 6a, in a creek-bottom where we often get late freezes. I have 3 Yellowhorn shrubs. About 7 years old & 5-7 ft tall. They get full sun. They get higher than average moisture because they’re near our well house. And our average here in NE Oklahoma is higher than you’d guess. They bloom profusely every spring, but I haven’t had a single nut from them yet. I believe I got these bareroot from Lawyer & I got seed from them, too. I’m thinking I may pull these 3 (where they have prime real estate) & try again from seed somewhere less useful. I had high hopes for them—dang!
