<i>Asclepias tuberosa</i> Species of flowering plant

Asclepias tuberosa, commonly known as butterfly weed, is a species of milkweed native to eastern and southwestern North America. 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.

<span class="mw-page-title-main">Monarch butterfly</span> Milkweed butterfly in the family Nymphalidae

The monarch butterfly or simply monarch is a milkweed butterfly in the family Nymphalidae. Other common names, depending on region, include milkweed, common tiger, wanderer, and black-veined brown. It is amongst the most familiar of North American butterflies and an iconic pollinator, although it is not an especially effective pollinator of milkweeds. Its wings feature an easily recognizable black, orange, and white pattern, with a wingspan of 8.9–10.2 cm (3.5–4.0 in). A Müllerian mimic, the viceroy butterfly, is similar in color and pattern, but is markedly smaller and has an extra black stripe across each hindwing.

<i>Asclepias</i> Genus of flowering plants

Asclepias is a genus of herbaceous, perennial, flowering plants known as milkweeds, named for their latex, a milky substance containing cardiac glycosides termed cardenolides, exuded where cells are damaged. Most species are toxic to humans and many other species, primarily due to the presence of cardenolides. However, as with many such plants, some species feed upon them or from them. The most notable of them is the monarch butterfly, which uses and requires certain milkweeds as host plants for their larvae.

<i>Asclepias syriaca</i> Species of flowering plant

Asclepias syriaca, commonly called common milkweed, butterfly flower, silkweed, silky swallow-wort, and Virginia silkweed, is a species of flowering plant. It is native to southern Canada and much of the United States east of the Rocky Mountains, excluding the drier parts of the prairies. It is in the genus Asclepias, the milkweeds. It grows in sandy soils as well as other kinds of soils in sunny areas.

<i>Asclepias incarnata</i> Species of flowering plant

Asclepias incarnata, the swamp milkweed, rose milkweed, rose milkflower, swamp silkweed, or white Indian hemp, is a herbaceous perennial plant species native to North America. It grows in damp through wet soils and also is cultivated as a garden plant for its flowers, which attract butterflies and other pollinators with nectar. Like most other milkweeds, it has latex containing toxic chemicals, a characteristic that repels insects and other herbivorous animals.

<span class="mw-page-title-main">Butterfly gardening</span> Gardening to benefit butterflies

Butterfly gardening is a way to create, improve, and maintain habitat for lepidopterans including butterflies, skippers, and moths. Butterflies have four distinct life stages—egg, larva, chrysalis, and adult. In order to support and sustain butterfly populations, an ideal butterfly garden contains habitat for each life stage.

<i>Asclepias curassavica</i> Species of flowering plant

Asclepias curassavica, commonly known as tropical milkweed, is a flowering plant species of the milkweed genus, Asclepias. It is native to the American tropics and has a pantropical distribution as an introduced species. Other common names include bloodflower or blood flower, cotton bush, hierba de la cucaracha, Mexican butterfly weed, redhead, scarlet milkweed, and wild ipecacuanha.

<i>Asclepias purpurascens</i> Species of flowering plant

Asclepias purpurascens, the purple milkweed, is a herbaceous plant species. It is in the genus Asclepias, making it a type of milkweed. It is native to the Eastern, Southern and Midwestern United States similar to the range of the common milkweed. The plant gets its name from the flowers that first develop a pink color but then turn darker purple as they mature. Unlike common milkweed, purple milkweed prefers some shade and is considered a plant of partial shade. It is also considered an indicator of oak savanna, especially in Wisconsin. The species rarely produces seed pods which are smooth, instead of the rough warty ones produced by common milkweed.

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.

<i>Rhyssomatus lineaticollis</i> Species of beetle

Rhyssomatus lineaticollis, also known by its common name Milkweed stem weevil is a species of weevil whose adults feed on the stems of the common milkweed, Asclepias syriaca. It is also destructive to the rare and threatened milkweed species Asclepias meadii.

<i>Asclepias cryptoceras</i> Species of plant

Asclepias cryptoceras is a species of milkweed known by the common names jewel milkweed, pallid milkweed, Humboldt Mountains milkweed, and cow-cabbage. It is native to the Great Basin of western North America, where it grows in many types of habitat, especially dry areas. This is a perennial herb growing low against the ground or drooping. It arises from a fleshy, woody rhizome-like root. The thick leaves are round to heart-shaped and arranged oppositely on the short stem. The inflorescence is a cluster of small flowers with centers of bright to dull pink hoods surrounded by pale-colored reflexed corollas. The fruit is a follicle held erect on a small stalk.

<i>Asclepias meadii</i> Species of flowering plant

Asclepias meadii is a rare species of milkweed known by the common name Mead's milkweed. It is native to the American Midwest, where it was probably once quite widespread in the tallgrass prairie. Today much of the Midwest has been fragmented and claimed for agriculture, and the remaining prairie habitat is degraded.

<i>Asclepias lanceolata</i> Species of plant

Asclepias lanceolata, the fewflower milkweed, is a species of milkweed that is native to the coastal plain of the United States from New Jersey to Florida and Southeast Texas. A. lanceolata is an upright, perennial plant that can grow between 3 and 5 feet tall, with red-orange flowers blooming in the summer months. It can also be referred to as Cedar Hill milkweed, as it was first described by Dr. Eli Ives in the neighborhood of Cedar Hill in New Haven, Connecticut.

<i>Asclepias sullivantii</i> Species of plant
