Care Guide

Planting

Plant your Cobb Mountain Lupine in full sun with fast-draining soil - this is non-negotiable, as poor drainage is where most plantings fail. Space it about 12–18 inches from other plants, since it reaches roughly half a meter tall. Spring is your best planting window (March through May, when it blooms). This lupine tolerates a variety of soil types as long as drainage is excellent, so amend heavy clay with compost or perlite before planting.

After Planting

Water moderately through your first summer to establish the plant, tapering off as fall approaches. Once established, this is a fairly low-maintenance perennial that doesn't require much fussing - just ensure it never sits in wet soil. The plant is deer resistant, so you won't need to protect it from browsing. Expect it to bloom in spring (March–May) and treat it as a perennial; the data doesn't specify pruning needs, so let it grow naturally unless you see dead wood to remove.
