Mulberry is a large, fast-growing native shade tree that also happens to produce sweet, blackberry-like fruit, prized by birds and other wildlife as much as by the people who plant it.
How mulberry fits zone 8's season
Zone 8b's frost-free window runs about 230 days, from March 25 to November 10. Mulberry takes about 3 growing seasons to reach first worthwhile harvest, so what matters here is how many of these seasons it gets, not whether one is long enough.
Mulberry is hardy in zones 4-9, so in zone 8b it stays in the ground through winter and comes back rather than being replanted. Allow about 8 ft of spread at maturity.
