Actually, no. Monarch caterpillars do only eat plants in the Milkweed family (Asclepias spp), so if we want to help them out in our wildlife gardens, we still need to add these plants to our gardens. Monarch caterpillars do not feed on tomato plants, despite what may seem like circumstantial evidence to the contrary.
Swamp milkweed, as the name suggests, grows best in moist, wetland areas. It likes wet, clay soil, but it also prefers full sun. The plant is hardy in USDA zones 3 through 6, where it grows as a perennial.
Swamp milkweed spreads through rhizomes; established plants can be divided in late spring. Swamp milkweed is a relatively long-lived (and slow-growing) herbaceous perennial. Swamp milkweed attracts the orange milkweed aphid.. . . . .364011235356!]
