Bred in Minnesota, so it's one of the few Wisterias that can be enjoyed by Northern gardeners! It blooms in early summer, rests a bit and starts all over again, and can even bloom a third time. This native selection grows to 15-25', so give it a sturdy support like an arbor, pergola or wall. Needs no pruning to bloom, but flowers best in full sun. Zones 4-9. Wisteria macrostachya 'Blue Moon'. Full Sun.
