HOW TO GROW
Sowing: Direct sow these great coneflower seeds for sale in the spring, pressing into the surface of the soil since this plant needs light to germinate.

Growing: Water seedlings regularly until they become established. This plant grows very quickly and needs little care, though it grows best in moist soil. Mature plants tolerate heat as well as some drought, but grow best with occasional watering in dry weather. Deadhead for the longest blooming period. Mature plants can be divided. This plant attracts butterflies, and may self-seed.
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.

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.
