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. [2] [3] [4] 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 ...
Grown from seed plants will take about two to three years to reach flowering size in average conditions. [17] The seeds do not require stratification and can be immediately planted, though in commercial growing they are generally moist stratified at 5 °C for 30–60 days because this increases the germination rate.
The seeds of some milkweeds need periods of cold treatment (cold stratification) before they will germinate. [12] To protect seeds from washing away during heavy rains and from seed–eating birds, one can cover the seeds with a light fabric or with an 13 mm (0.5 in) layer of straw mulch. [13] However, mulch acts as an insulator. Thicker layers ...
All parts of common milkweed plants produce a white latex when cut. The simple leaves are opposite, sometimes whorled; broadly ovate-lanceolate. They grow to 10–28 cm (4–11 in) long and 4–12 cm (1 + 1 ⁄ 2 – 4 + 3 ⁄ 4 in) broad, [5] usually with entire, undulate margins and reddish main veins.
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. [ 3 ] [ 4 ] 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 .
You can easily spot the flower clusters (technically, umbellate cymes) in open meadows. Milkweed plants are a major food source for Monarch and Queen butterfly caterpillars and as with other milkweed plants, it bleeds white latex if a stem is cut and this sap is toxic to some animals and to humans.
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. [1] Today much of the Midwest has been fragmented and claimed for agriculture, and the remaining prairie habitat is degraded. [1]
The native habitat of the plant includes prairie and meadows. [2] It grows in moist areas, such as river bottomland. [1] The original range of Asclepias sullivantii was the tall grass prairie, but very little of that habitat remains because of wide spread conversion to farming. [4]
