Milkweed is a group of plants named for their milky sap. Our tropical milkweed has orange, yellow, and red tubular flowers. It blooms during much of the year and reseeds freely. They’re an important nectar source for insects, and serve as host plants for certain butterflies. In fact, milkweed is the only food source for monarch’s and they’ll munch through it like crazy! They prefer full sun and we recommend fertilizing with Espoma Flower-tone, a superb organic choice.
