Swamp Milkweed

Asclepias incarnata subsp. incarnata

Swamp Milkweed (Asclepias incarnata subsp. incarnata) is a low-growing perennial wildflower native to the United States. The plants form clumps of upright green stems, and in summer, they produce clusters of sweetly fragranced pink and white flowers. The flowers attract a wide variety of beneficial insects, such as bees and butterflies, making it a great choice for butterfly gardens. The plants are drought-tolerant and flourish in wet, marshy areas, making them a wonderful choice for naturalizing wet areas. After flowering, the plant produces clusters of oval, seed-filled pods. Swamp Milkweed is a great choice for low maintenance gardens and is sure to add beauty and interest to any space.

watering

Goat's Beard requires regular watering for optimal growth. During the growing season (spring to fall), water the plant once weekly or every other week, making sure to keep the soil moist but not saturated. Do not allow the soil to dry out completely between waterings. Watering in the morning is preferable to avoid fungal diseases, as evaporation of water from the leaves is at its lowest. In the winter, reduce watering to every 3 to 4 weeks or when the soil starts to feel dry. Do not over water in the winter, as this can cause root rot and other fungal diseases. Be sure to water the plant regularly and at the root zone, not the foliage.

sunlight

Goat's Beard (Aruncus dioicus var. acuminatus) thrive when planted in sunny to partially shaded areas. They prefer at least 4 hours of direct sunlight during the daytime, with either morning or afternoon sun being ideal. If planted in a shadier location, a plant may not bloom as profusely as in a more sunny 1. In areas with hotter climates, some shade for a few hours during the hottest part of the day is recommended.

pruning

Goat's Beard (Aruncus dioicus var. acuminatus) should be pruned in late spring once it has finished flowering. The ideal time for pruning is when the new growth has emerged but before the flowers have opened. Pruning should be only light to moderate. Cut back about 1-third of the growth to encourage bushier plants. Remove any dead stems, leaves or flowers as well as any that are crowding the interior of the plant. Deadheading (removing spent flowers) may be done to promote a second flush of blooms. If necessary, thin out stems and cut them to the ground.
