Asclepias tuberosa, also known as butterfly weed, is a wonderful perennial plant native to Texas. It thrives beautifully in the dry, rocky open woods, meadows, prairies, fields, and roadsides across the state. This charming plant typically grows in a delightful clump ranging from 1 to 2.5 feet tall and showcases clusters (umbels) of bright, cheerful orange to yellow-orange flowers perched atop hairy stems with narrow, lance-shaped leaves. Unlike many milkweeds, this lovely species doesn’t have milky-sapped stems.
The vibrant butterfly weed flowers transition into spindle-shaped seed pods, measuring 3 to 6 inches long, which split open when ripe, releasing a multitude of silky-tailed seeds that dance through the wind. The seed pods are a favorite in dried flower arrangements, and this plant has a wonderfully long bloom period, spanning from late spring to summer. The flowers are a delightful source of nectar for many butterflies, while the leaves serve as a nutritious food source for monarch butterfly larvae (caterpillars). Historically, the plant’s roots have been used medicinally to soothe lung inflammations, and it’s also fondly referred to as pleurisy root.
Butterfly weed is a breeze to grow in average, dry to medium, well-drained soils under full sun. It’s drought-tolerant and thrives even in poorer, dry soils. You’ll often see new growth emerging late in the spring, and these plants can be quickly cultivated from seeds. However, be patient; they may take 2 to 3 years to bloom. If seed pods aren’t removed before they burst open, mature plants can happily self-seed throughout the landscape. Butterfly weed doesn’t transplant well due to its deep taproot, so it’s best to let it settle in once established.
