The perennial Lupine is a North American native that was introduced to Europe by 1658 and listed in Philadelphia nurseryman Bernard McMahon's 1804 Broadside. The plant forms showy spikes of blue, pea-like flowers that are attractive to butterflies and hummingbirds, and large, palmately-lobed leaves arranged in a rosette.
Start seeds indoors 8-10 weeks before last frost date at 55 degrees F. Before sowing, scarify and pre-soak seeds overnight. Transplant to 3" pots once they have several true leaves, then harden off and transplant outdoors after last frost. Approximately 40 seeds per packet.
