Asclepias sp. (Milkweed)

Flowers of plants in this genus are produced in umbrel-like clusters with numerous small flower groups to 1 inch wide. The flowers are followed by green fruits that ripen to yellowish-brown and split open to reveal their seedy contents.

Milkweeds are known to be toxic to livestock and domestic fowl, but usually under conditions of forced ingestion of large quantities through mismanagement or drought.
