Narrowleaf Milkweed

asclepias fascicularis

Narrowleaf Milkweed (Asclepias fascicularis) is a resilient perennial herb native to the western United States. Highly prized by gardeners and conservationists alike, this plant features slender, lance-shaped leaves and dense, rounded clusters of delicate, star-shaped white-to-lavender flowers. It serves as a vital ecological cornerstone in its native range, supporting a myriad of pollinating insects and acting as a critical host plant for the iconic Monarch butterfly.

生息地: Typically found in dry, open habitats including valleys, foothills, chaparral, deserts, grasslands, and along roadsides.

外見

This plant typically grows upright to a height of 50 to 100 cm. It is easily distinguished by its exceptionally narrow, linear leaves that grow in tight whorls or opposite pairs along the slender, greenish-purple stems. From late spring to early autumn, the plant produces rounded, umbrella-like clusters of small, 5-petaled flowers which range in color from greenish-white to pale pink or lavender. After pollination, it develops smooth, slender, teardrop-shaped seed pods that eventually split open to release flat, brown seeds attached to silky, white fluff.

おもしろい事実

Indigenous peoples historically harvested the strong, fibrous stems of this plant to weave high-quality ropes, nets, and bowstrings.

The plant's milky sap contains toxic cardiac glycosides, which monarch caterpillars safely ingest to make themselves highly unpalatable to birds.

Unlike most flowers that have loose pollen, milkweed packages its pollen into tiny, sticky sacks called pollinia that clip onto the legs of visiting insects.

特殊能力

Synthesizes toxic cardiac glycosides within its milky white sap to deter generalist herbivores from eating its foliage.

Utilizes a deep, extensive taproot system to access water deep within dry, clay-heavy soils during hot summer months.

Produces seeds equipped with silky, lightweight hairs that catch the wind, allowing them to disperse over great distances.
