Tall Evening Primrose Seeds
Oenothera hookeri
- HOW TO GROW
- FAST FACTS
HOW TO GROW
Sowing: Direct sow in early spring, pressing lightly into the surface of the soil since this seed needs light to germinate. Keep the soil lightly moist until germination, which should occur within 10-30 days. When the seedlings can safely be handled, thin or transplant for wider spacing. For an early start, start the seed indoors 8-10 weeks before the last frost and transplant outdoors.
Growing: Water the seedlings until they become established. Mature plants can tolerate almost any type of soil, though they tend to wilt in extremely dry soil. This plant needs little care and grows easily; it can quickly spread and become invasive if not controlled, since it reseeds prolifically. To help prevent this, the plants can be cut back after blooming. This plant attracts birds and resists deer.
Harvesting: These short-lived blossoms do not make good cut flowers, and are best enjoyed in the wild.
Seed Saving: After flowering, slender ridged pods will develop; keep in mind that these pods provide food for small birds, and may need to be protected in order to preserve the seed. Eventually the pods will turn brown, split open, and drop their seed. Collect the pods as soon as they begin to turn brown, making sure the seed inside has ripened to a dark brown. After the pods have dried, remove the seed. Store the seed in a cool, dark place.
