Roll out the welcome mat for butterflies with one of their favorite flowers: butterfly weed (Asclepias tuberosa). Nectar- and pollen-laden blossoms beckon other pollinators, too, including bees, hummingbirds and other insects. Orange flowers are standard, but you can find varieties with yellow blooms, such as ‘Hello Yellow.’ A native plant, butterfly weed offers summer-long bloom when you remove the first round of spent flowers. Plants are slow to wake up in spring. Consider marking the spot to avoid disturbing still-dormant plants with early spring gardening. Deer- and rabbit-resistant plants grow 24 inches tall and wide. Hardy in Zones 3-9.
