Vines provide food, cover, and nesting sites for birds. You can't beat a vine near a bird feeder for cover. At the right time of year a vine is a bird feeder. Robins readily nest in vines that are on trellises.

Some vines are food sources for certain butterfly caterpillars. The variegated fritillary larva feeds on Passion Flower leaves, and the Pipevine Swallowtail larva feeds on Dutchman's Pipe Vine leaves.

Vines grow best and produce more fruit in sunlight or bright spots. More aggressive vines, like Trumpet Creeper and Virgin's Bower, should be planted so they can be mowed around to prevent their spread.

The sexes of American Bittersweet are on different plants, requiring both male and female plants to produce fruits on the females.
