Hi - This is tropical milkweed (Asclepias curassavica). Here is a fact sheet from the University of Florida Extension with information about this species.
Tropical milkweed is attractive to butterflies, bees, and other insects. If you are interested in growing milkweeds to support Monarch butterflies, however, the native milkweeds are recommended over this non-native species. This article explains why. https://xerces.org/blog/tropical-milkweed-a-no-grow
Our native butterfly milkweed (Asclepias tuberosa) is a nice alternative.
