Aesclepias incarnata-Swamp Milkweed

A. incarnata is commonly referred to as swamp milkweed because of its association with highly saturated soils in wetlands or areas that are flooded seasonally. Plants usually have a taproot with the root crown producing one to six or more stems each growing season. The flowers, which are said to give off a scent similar to cinnamon, are presented on medium sized erect umbels that tend to be flat. Swamp milkweed is self-compatible which contrasts with the self-incompatibility of other studied milkweeds.
