Green Comet Milkweed (Asclepias dregeana)
Description
Green milkweed is a perennial from a vertical rootstock. Two foot tall stems are mostly solitary or in pairs and bear are opposite leaves up to four inches long. Leaves are variable in shape with plants from dry sites having long narrow leaves and those from moist sites having round leaves. 20-80 pale green flowers occur in two inch clusters in upper leaf axils. The pods of green milkweed are about four inches long and pointed at both ends. The pods lack the warts or tubercles found on other common milkweeds. The specific epithet viridiflora means green-flowered in botanical Latin. Milkweed flowers have a special mechanism to trap insect legs and cause pollen masses to be pulled from the plant.
