Vines and Trees and Birds and Butterflies and Bees


Vines and Trees and Butterflies and Birds and Bees

The right combination of trees and vines can lead to lots of birds, butterflies and bees-beelieve or not. We’re developing such a combination over at the Freedom Park Bird and Butterfly Garden, corner of North Ave. and Candler Park Drive. When we decided on the site for the garden it happened to include four large White Oak trees (Quercus alba). Little did we realize how fortuitous this was, not being up to speed on the secret life of trees at the time. Since we’ve learned that the White Oak is a valuable food source for over 28 species of birds, including Blue Jays, American Crows, Red-headed Woodpeckers, Tufted Titmice and White -breasted Nuthatches, all of which have been seen or heard at the garden. The trees provide a huge benefit to wildlife populations because of their acorns, which are larger and sweeter than other oaks such as the red oak. In fact, including birds, 180 wildlife species prefer these acorns (www.Copeland.udel.edu). The White Oak can live for over 500 years and grows to 100 feet tall and is native to America.

Now, the White Oaks obviously don’t need any help to attract wildlife, but overachievers that we are, we decided to give them some help anyway-and that’s where the vines come in. We’ve gone ahead and planted a native vine by each of three of the trees, and each of these vines attracts birds and butterflies and bees! And here they are:

Passion Flower (Passiflora incarnata) is a host plant for the bright orange Gulf Fritillary, the Variegated Fritillary, and Zebra Butterflies. The size and structure of flowers of this plant is optimized for pollination by hummingbirds, bumble bees and wasps. The vine, with its exotic white and purple flowers can grow to 20 feet.

Climbing hydrangea (Decumaria barbara ) is an attractive deciduous vine with lace-cap like clusters of large white flowers in midsummer. This plant, too, is attractive to bees, butterflies and/or birds. Its also a favorite of deer though we’re not really expecting any. The vine can grow up to 40 feet high.

Crossvine on White Oak
Crossvine (Bignonia capreolata) is native to southeastern North America where it occurs widely in uplands, lowlands, forests, and clearings. The outside of the typical crossvine flower is red to brownish-orange, the inside yellow. It’s a hummingbird favorite, is drought tolerant and will grow to 40 feet.

So take a peek over at the garden, which, by the way, is a joint project of
Atlanta Audubon and the DeKalb Master Gardener Association.
