About Decurrent False Aster: This native wetland species has been placed on the list of threatened and endangered plants because of its decreasing growth in the wild. Currently, it can only be found growing in the wild around the floodplains and rivers of Illinois and Missouri; this species relies on regular flooding to become established in the wild. “Decurrent” refers to the clasping habit of the leaves that extend upward on the stem, while the term “false aster” comes from the fact that its flowers closely resemble asters.
Decurrent False Aster Germination: In late fall, direct sow the seed on the surface of the soil. For spring planting, mix the seed with moist sand and store it in the refrigerator for 60 days before direct sowing on the surface of the soil; these seeds need light to germinate. Keep the soil very wet until germination. Thin or transplant the seedlings to 30-36" apart.
Growing Decurrent False Aster Seeds: Keep the soil very moist; this plant naturally occurs in floodplains and can thrive even in standing water, though it also tolerates average soil. Taller plants may need support or staking. For tidier growth, the plant may be pruned back by one third before the the buds form. Keep weeds down to a minimum, since it does not do well with competition. This plant attracts butterflies.
Harvesting Decurrent False Aster: For fresh flowers, cut the stems at ground level and place them in water immediately.
Saving Decurrent False Aster Seeds: After the flowers fade, the seed heads will form mature seed. Ripe seed will be a pale tan color, and light enough to be carried by the wind. Shake the plant over a container to gather the ripe seed. Store the seed in a cool, dry place.
