HOW TO GROW
Sowing: Direct sow in late fall, pressing into the surface of the soil since this plant needs light to germinate. Keep the soil lightly moist until germination, which usually takes 2-3 weeks. The Rudbeckia Amplexicaulis seeds can also be started indoors 6-8 weeks before planting in spring. Keep seedlings lightly moist, and transplant them as soon as they have developed several leaves.
Growing: Water seedlings regularly until they become established. This plant grows very quickly and needs little care, though it grows best in fairly moist soil. Mature plants also tolerate heat and drought, though they prefer moisture and will benefit from occasional watering in dry weather. Deadhead for the longest blooming period. The Rudbeckia Amplexicaulis 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.
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 clasping coneflower seed in a dry, cool place.
