Butterfly Weed, beautiful flowers

While its cousin, common milkweed, is likely to spread through as much of your garden as it can, the "more restrained" butterfly weed will attract plenty of its namesake pollinators without the aggressive takeover. "Butterfly weed is vibrant orange or yellow-orange (or more rarely reddish-orange)," says Talabac. "They bloom around midsummer, and some species have appealing fragrances. Monarch and Queen butterflies will use many species of milkweed as host plants for their caterpillars."
