Spacing: about 20 square feet per plant (square-foot-gardening spacing). Mature height: 3-6 ft.

Honeyberry, also called haskap, is one of the most cold-hardy and shade-tolerant fruiting shrubs available, worth considering for a spot too cold, wet, or shady for most other berries to thrive in.

How honeyberry (haskap) fits zone 3's season

Zone 3b's frost-free window runs about 98 days, from May 30 to September 5. Honeyberry (Haskap) takes about 2 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.

Honeyberry (Haskap) is hardy in zones 2-7, so in zone 3b it stays in the ground through winter and comes back rather than being replanted. Allow about 4 ft of spread at maturity.
