Native Range:
Asclepias physocarpa is originally native to southeast Africa. However, due to its unique appearance and benefits to wildlife, it has been introduced to various parts of the world, including North America. In North America, it has naturalized in certain areas but is not considered native to any specific states or provinces. Neither is it considered generally invasive in the same areas.
USDA Zones:
The Balloon Plant thrives in USDA hardiness zones 8 to 11, where the climate remains relatively mild during the winter months.
Seeds
Butterfly Seeds are Seeds for butterfly Larval Host Plants. The caterpillar (larva) can only eat their specific Larval Host Plant! Without that plant around, you will not have that butterfly. E.g. Black Swallowtails require plants in the Carrot family.
