Asclepias viridis, Green Antelope Horn Milkweed

Popular Featured


A. viridis is one of Oklahoma’s most common milkweed species and of incredibly high value to monarchs during the spring migration. A. viridis is very attractive to bees, beetles, and butterflies. If growing A. viridis in a controlled setting like a hoop house or greenhouse, use well-draining soil. If you are using black plastic trays, take care when watering that the water doesn’t weigh the plant down causing it to have contact with hot trays as they will probably burn.
