This plant is a friend to bees and butterflies, in addition to providing nutritious seeds for birds.
Sow directly in the garden in early spring at a depth of ½ inch in rich, moist soil. Germination should occur within 7 to 10 days.
Water the seedlings until they are well-established. Mature plants can tolerate drought. Prune the branch heads to allow the plant to be more bushy. It may be necessary to support the branches with a stake if they become too large.
