Milkweeds are most easily recognized by their unique flowers and best known for their attractiveness to butterflies. Some are low-growing, others tall and conspicuous. Flower color ranges from white to lavender, green, yellow, or bright orange-red. Lanceleaf Milkweed, shown here, can be 3-4′ tall, which makes it a conspicuous component of wet roadside ditches.
