Green Milkweed

Green Milkweed, Asclepias viridis

Green Milkweed, also known as green antelopehorn (not to be confused with clumping milkweed antelope horns) is a native milkweed common in pastures, prairies, and ditches from Nebraska to Ohio and Texas to Florida.  Within Texas, green milkweed is the most common milkweed and can be found on most soils, but prefers loamy, moist soils. It blooms from April through September and can grow up to 0.9 m (3 ft) in height. There is usually only one umbel, or flower cluster, per stem, but larger plants may have more. As with most milkweeds, the sticky, milky substance is toxic, but has been utilized by certain butterfly species, most notably, monarchs. Both native and non-native bees have been known to pollinate milkweed.
