Monarch Butterflies are fully and exclusively dependent upon milkweeds for laying eggs and for larva food source and they can nectar. These plants were once so plentiful they were literally called weeds because they were problematic in agricultural fields. However, that's no longer the case with regular Glyphosate treatments to agricultural fields wiping out all "weeds". With fragmentation, global climate change, pollution, and other threats this is a major problem for Monarch butterflies that heavily depend upon the milkweed and other native plants. Monarch caterpillars need milkweeds, but also nectar sources that many native flowers provide. Help keep these going! Please consider your part in this planet, plant Monarch food sources including milkweed and other native plants.
Asclepias incarnata (Swamp Milkweed) is easily one of the best milkweeds for landscaping because it is well behaved, beautiful, and resilient. Even though it is called "Swamp Milkweed" it is a terrific normal/medium moisture and it works well in rain gardens. It prefers sunny sites but can work in part sun and forms larger clumps in optimal conditions. Besides being a monarch host plant, its flowers are a preferred nectar plant, even for a random hummingbird or two.
