Asclepias erosa | |
Asclepias erosa is a species of milkweed known commonly as desert milkweed. It is native to southern California, Arizona, and northern Baja California, where it is most abundant in the desert regions.
This milkweed, Asclepias erosa, is a perennial herb with erect yellow-green stems and foliage in shades of pale whitish-green to dark green with white veining. It may be hairless to very fuzzy. The sturdy, pointed leaves grow opposite on the stout stem. Atop the stem is a rounded umbel of yellowish or cream-colored flowers. Each flower has thick, reflexed corollas beneath a flower center composed of rounded, horned filaments.
The plant is filled with a viscous sap that was roasted to a solid and enjoyed as a sort of chewing gum by local Native American groups. Researchers in Bard, California tested the plant as a potential source of natural rubber in 1935. [1]
Asclepias erosa is a specific monarch butterfly food and habitat plant.
Asclepias tuberosa, the 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. It is also a larval food plant of the queen and monarch butterflies, as well as the dogbane tiger moth, milkweed tussock moth, and the unexpected cycnia.
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 may be the most familiar North American butterfly, and often is considered an iconic pollinator species, 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+1⁄2–4 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.
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, although, as with many such plants, there are species that feed upon them and from them. Most notable are monarch butterflies, who use and require certain milkweeds as host plants for their larvae.
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.
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.
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.
Asclepias verticillata, the whorled milkweed, eastern whorled milkweed, or horsetail milkweed, is a species of milkweed native to most all of eastern North America and parts of western Canada and the United States.
Asclepias fascicularis is a species of milkweed known by the common names narrowleaf milkweed and Mexican whorled milkweed. It is a perennial herb that grows in a variety of habitats.
Asclepias californica is a species of milkweed known by the common name California milkweed. It grows throughout lower northern, central and southern California.
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.
Asclepias subulata is a species of milkweed known commonly as the rush milkweed, desert milkweed or ajamete. This is an erect perennial herb which loses its leaves early in the season and stands as a cluster of naked stalks. Atop the stems are inflorescences of distinctive flowers. Each cream-white flower has a reflexed corolla that reveals the inner parts, a network of five shiny columns, each topped with a tiny hook. The fruit is a pouchlike follicle that contains many flat, oval seeds with long, silky hairlike plumes. This milkweed is native to the desert southwest of the United States and northern Mexico.
Asclepias cordifolia is a species of milkweed commonly called heart-leaf milkweed or purple milkweed. It is native to the western United States, growing between 50 to 2,000 m elevation in the northern Sierra Nevada and Cascade ranges. Heart-leaf milkweed was valued by the Native American Miwok tribe for its stems, which they dried and processed into string and rope.
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.
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.
Asclepias welshii is a rare species of milkweed known by the common name Welsh's milkweed. It is native to southern Utah and northern Arizona, where there are four known occurrences remaining. Most of the plants occur in Coral Pink Sand Dunes State Park, where the habitat has been degraded in many areas by off-road vehicle use. It is a federally listed threatened species of the United States.
Asclepias viridis is a species of milkweed, a plant in the dogbane family known by the common names green milkweed, green antelopehorn and spider milkweed. The Latin word viridis means green. The plant is native to the midwestern, south central and southeastern United States, as well as to the southeastern portion of the western United States.
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.
Asclepias sullivantii is a species of flowering plant in the milkweed genus, Asclepias. Common names include prairie milkweed, Sullivant's milkweed, and smooth milkweed. It is native to North America, where it occurs in the central United States and Ontario in Canada.

It is a widely distributed species of milkweed (Asclepias), known from much of the eastern and central United States from Connecticut to Georgia to Arizona to Montana, as well as southern Canada. The Latin specific epithet viridiflora means green-flowered.
