How to grow wild lupine

When to plant wild lupine

Wild lupine is a cool-weather perennial that blooms in late spring to early summer; NC State notes it prefers cool growing conditions and that seed germinates better after scarification. The page gives no explicit sowing date, so a spring planting band is approximate.

Wild Lupine is timed by season rather than your frost dates, so the planting calendar does not generate ZIP-specific dates for it. Check the cited sources below to fine-tune for your area.
