How to Plant and Grow Lupine
Plant Lupine Seeds: Chip lupine seeds with nail clippers, or soak in warm water overnight prior to sowing. Sow in peat pots or cell packs, and lightly cover. Kept at 65-75°F., germination averages 14-21 days. Can direct sow lupine seeds into the garden in groups of 3 or 4 seeds, spaced 24-36 in. apart. Thin to the strongest plant.
Grow Lupine: Sun or part shade. Will flower the first year when started early. Plants prefer rich, moist soil, and mild temperatures. In hot summer areas lupines are grown as annuals; they are planted in October to flower in March and April. Plants resist deer and rabbits. Nectar rich flowers attract butterflies and hummingbirds.
