Description
Asclepias Tuberosa, commonly known as butterfly weed or orange milkweed, is a species of milkweed that is native to North America. It is a perennial plant that grows up to 1-2 feet tall and 1-2 feet wide. The plant produces clusters of bright orange flowers in the summer, which attract butterflies and other pollinators. The flowers are followed by long, narrow seed pods that split open when ripe, releasing seeds with silky hairs that are carried by the wind.
