Lupine (Lupinus) is an attractive perennial that produces showy flower spikes in a variety of colors, including purple, pink and yellow. The foliage of the lupine plant can grow up to 5 feet tall with blooms reaching heights of up to 4 feet. This plant is easy to start from seed and will do well as long as its basic growing requirements are met. The seeds should be sown directly into the garden, as lupine does do not do well when transplanted.
Clip off the lupine seed pods when they begin to dry and become yellow. This will occur a few weeks after the last blooms have faded. Place the seed pods into a screen box. Lupine seeds pop open on their own when ripe and this will ensure that none of the seeds are lost.
Moisten a paper towel and place it into a plastic bag. Add the lupine seeds and seal the bag. Place into the refrigerator and allow the seeds to remain there for seven days.
Prepare a location in your yard or garden by removing all grass, weeds and large rocks. Loosen the soil to a depth of 12 to 20 inches.
Sow the seeds in the prepared location and cover with 1/8-inch of soil. Water until the soil is thoroughly moistened.
Add water whenever the top of the soil feels dry. The seedlings should begin to appear in 15 to 75 days. Thin the seedlings once they have emerged, leaving 12 inches between each plant.
