HOW TO GROW

Sowing: Direct sow in late fall, pressing into the surface of the soil. For spring planting, mix the seeds with moist sand and store in the refrigerator for 60 days before planting. Keep the soil consistently moist until germination.

Growing: Water seedlings occasionally until they become established. Mature plants prefer slightly dry soil and tolerate drought, in addition to growing well in clay or sandy soils. This plant attracts bees, butterflies, and hummingbirds. It may self-seed in good growing conditions.

Harvesting: For cut flowers, choose stems with flowers that have just opened. Strip the foliage that will fall below the water level, and place in water immediately.

Seed Saving: After the flower petals fall from the head, the center cone will begin to develop seed. Remove the seed heads as soon as the stem beneath the cone begins to turn dry and brown. Spread the seed heads out to dry away from direct sunlight, then separate the small seeds from the stems by rubbing them lightly. Store the cleaned seed in a dry, cool place.

DESCRIPTION

According to legend, settlers on the American prairies once depended on the leaves of this native plant to point the way north. The towering stalks of yellow flowers are valued as a source of pollen for various insects, making it a popular choice for native plant projects.
According to legend, travelers on the American prairies once depended on the leaves of this plant to point the way north. Dr. Asa Gray, one of the most influential 19th century American botanists, theorized that the specific orientation of the leaves allowed the plant to conserve water. The genus name "Silphium" comes from the Greek word "silphion," the name of an ancient plant with similar properties to this one.
