This striking plant has brilliant reddish-orange flowers, although sometimes they are yellow or white. It grows to a height of 1 to 2 feet and prefers dry or mesic conditions. Butterfly weed is toxic to most animals, except certain insects that have evolved to benefit from it, which luckily for anyone who has this plant, includes Monarch butterflies. They love this plant and often lay their eggs on it. Many other insects, however, will visit it.
Blooms: June through the end of July or early August.
