Lay the seeds on top of the soil, spacing the seeds 12 inches apart. Cover the seeds with 1/8 inch of soil and sprinkle water over the planting area. Keep the soil moist throughout the germination process. It takes 15 to 75 days for lupine sprouts to appear when the soil is 55 to 70 degrees Fahrenheit.

Do lupins come back every year?

Lupins from Seed or Plants? Lupins are perennial (i.e. they come up year after year) shrubs which start into growth after the last frosts, produce their first flush of flowers in late May / June and can continue flowering into early August if dead-headed correctly (see below).

How long does it take for lupines to sprout?

At room temperature, about 72 degrees F, you should see lupine seedlings poking through the soil in five to six days. Although lupines have a reputation for low, erratic germination, more than 90 percent of carefully handled domesticated seeds should eventually sprout.
