Agapanthus, also known as lily-of-the Nile, is a summer-flowering plant, native to South Africa. Grown in clumps, the plants produce long stalks (up to 6 feet in height) that bear clusters of tiny, lily-like lavender or white flowers. Agapanthus is generally propagated by root division as growing them from seed is a long process and the plants grown will take three to four years to flower. Sow the agapanthus seeds in early spring. Agapanthus is hardy to U.S. Department of Agriculture Plant Hardiness Zones 7 through 11.
Combine equal parts of sand and compost and pour it into the seeding tray. Run water over the soil until the water runs from the bottom of the tray. Allow the soil to drain completely.
Place the seeds, 3 inches apart, on the top of the soil and cover with a 1/4 inch layer of moist soil.
Place the seeding tray in a shady area that remains between 70 and 80 degrees F. Use the plant misting bottle, filled with water, to mist the soil to keep it moist. The seeds should sprout within one to two months.
Transplant each seedling into its own pot when they reach 4 inches high; this may take up to one year. Use the same soil mixture that you used for germination. Place the pots in a sunny area. In hot regions, move the pots into the shade in the afternoon.
Transplant the seedlings into the garden in their third year.
