Like other milkweed species, this plant is a host plant for the monarch butterfly whose caterpillars feed on the leaves. The plant is toxic to livestock. [3] Uses
It is a larval food of monarch butterflies [4] and milkweed tussock moth larvae. [5] C. laeve can cause eye irritation if touched and can be toxic to humans and livestock if consumed in large quantities. [6]
Asclepias tuberosa, commonly known as butterfly weed, is a species of milkweed native to eastern and southwestern North America. [2] It is commonly known as butterfly weed because of the butterflies that are attracted to the plant by its color and its copious production of nectar .
Hungry or thirsty horses are more likely to eat poisonous plants, as are those pastured on overgrazed lands. [5] Animals with mineral deficiencies due to poor diets will sometimes seek out poisonous plants. [6] Poisonous plants are more of a danger to livestock after wildfires, as they often regrow more quickly. [7]
Calotropin is a toxic cardenolide found in plants in the family Asclepiadoideae. In extreme cases, calotropin poisoning can cause respiratory and cardiac failure. Accidental poisoning is common in livestock who have ingested milkweed. Calotropin is commonly stored as a defense mechanism by insects that eat milkweeds as their main food source.
Like several other species of milkweed, A. asperula is a food for monarch butterfly caterpillars. Along with being food for monarchs, the plants also contain toxic cardiac glycosides (cardenolides) that the monarchs retain, making them unpalatable and poisonous to predators.
The fine, silky fluff attached to milkweed seeds, which allows them to be distributed long distances on the wind, is known as floss. Milkweed floss is incredibly difficult to spin due to how short and smooth the filaments are, but blending it with as little as 25% wool or other fiber can produce workable yarn. [29]
Asclepias speciosa is a milky-sapped perennial plant in the dogbane family (Apocynaceae), known commonly as the showy milkweed and is found in the western half of North America. [ 1 ] [ 2 ] Description
