Top 10 Butterfly Host Plants to Attract Pollinators

Ready to take butterfly gardening to the next level? Plant butterfly host plants to give caterpillars food to eat and a place to grow through their lifecycle.

Nectar plants give butterfly gardens a powerful boost. But they’re not the only key to drawing pretty pollinators to your yard. As your favorite winged beauties transition through their life cycle, many lay eggs on the undersides of specific host plants. And butterflies do most of their eating during their larval phase as caterpillars, feeding exclusively on the leaves of host plants specific to their species. Many people know monarchs need milkweed, but there are many other butterfly host plants you should consider adding to your garden. By incorporating some of these, you’ll attract a wider variety of butterflies to your backyard. And they just might stick around!

Willow

Salix, Zones 2 to 9

It’s true! Caterpillars feed on trees as well as pretty garden plants. Willows are known to grow up to 100 feet depending on species. So most gardeners will want smaller willows, like Dappled or Flame willow, which are a better size for backyard landscapes. Willow trees prefer full sun and tolerate many
soil types.
Butterfly benefits: Several caterpillars like to munch on willow trees, including viceroy, western tiger swallowtail and mourning cloak.

Oak

Quercus, Zones 3 to 10

You may know oak trees by the fantastic orange, red and yellow foliage show they put on every autumn. Mature oaks can reach up to 100 feet high, but you can find smaller varieties, such as pin oak, that grow to about 75 feet-still quite large. So keep in mind that even smaller varieties need plenty of space to grow and flourish.

Butterfly benefits: Young oak leaves are favorite butterfly host plants of the caterpillars of Horace’s duskywing and banded hairstreak.

Switchgrass

Switchgrass

Panicum virgatum, Zones 4 to 9

This easygoing and versatile grass is a good choice for wet conditions, drought or partial shade, as long as it’s planted in moist, well­-draining soil. Growing narrow and upright with a cloud of seed heads in fall, switchgrass can reach more than 5 feet tall. Birds enjoy the seeds while the green leaves turn to yellow in fall.

Butterfly benefits: These butterfly host plants serve as food and shelter. Many skipper caterpillars need grasses like switchgrass as a food source. These same caterpillars might overwinter on or underneath the blades of grass.
