Giant Milkweed – Calotropis gigantea

Huge milkweed leaves, tall bushy plant … it’s the dream of a Monarch enthusiast, especially one that brings in caterpillars and raises them indoors. For gardeners who live so far south in the US that they can’t grow common milkweed (Asclepias syrica), Giant Milkweed (Calotropis gigantea) is fantastic.
