Sassafras Trees for Attracting Birds, Butterflies, and Moths

The Sassafras tree is covered with brilliant leaves in reds, oranges, and golds.

With the shortening of daylight, photosynthesis has stopped. The tree has stopped making chlorophyll and the other pigments that were always present are now able to show themselves. The red, orange, and yellow colors are a result of certain chemicals present in the leaves. (See Why Do Leaves Change Color).

The leaves come in three slight variations of un-lobed or lobed on one or two sides. The lobed leaves look like mittens. The leaves range in size from 2 1/2 to 6 inches long on the same tree.

Attracting Birds, Butterflies and Moths

We humans like the brilliant fall color and birds like the fleshy blue fruits on bright red stalks. The seeds are disbursed by birds (See The Relationship Between Birds. Berries, and Fruit)

The fruit is produced only on female trees.

This tree beside my community garden plot doesn’t have fruit so I guess it is a male.

Not only will the birds like the trees for nesting or fruit but so will butterflies and moths. The sassafras is a known host plant for Tiger and Spicebush Swallowtail butterflies and several moths. The Sassafras is the hostplant of Promethea, Imperial, Palamedes, Io, and Silk moths. The Butterly and moth larvae eat the fleshy leaves.

The tree’s small size and fleshy blue fruit make it a good choice for attracting birds, butterflies, and moths to your backyard or garden.

Growing Sassafras in Your Backyard or Garden

The Sassafras tree is indigenous to Eastern North America. It ranges from Vermont and New Hampshire to northern Florida and west to Missouri and eastern Texas.

And for some reason it’s not found in northern New York state or Pennsylvania. It can be found growing naturally in fencerows, forest edges or along roadsides. Where it chooses to grow naturally tells us how to grow it in gardens.

Since Sassafras likes forest edges that means it needs sun and not deep shade you find in a mature forest with a closed canopy. So find a sunny spot for it. The tree is intolerant of road salts. So, hellstrips in sidewalks and along roadsides that receive winter salt are not good places for it.

Once established it will adapt to most soils. It can tolerate from sandy to silty clay soils with hardpan. But apparently the plant does not transplant well. It seems because of this nurseries may not carry it. But some nursery somewhere does. Supplying young Sassafras grown from seed is a good opportunity for small-scale home-based plant nurseries.

But if you would like to grow this plan in your back yard habitat or garden you can become your on “plant hunter”. You can start a tree from seeds planted outdoors in the fall of the year. Or you can buy one from a nursery. The tree spread through its prolific ability to form root shoots.And there is always propagation by cuttings.

Sassafras doesn’t suffer from serious insect or disease problems. And the wood is resistant to decay. The wood is aromatic and rot resistant.All parts of the tree have a spicy aromatic scent. The tree has long been used by North American indigenous peoples and others for its medicinal qualities. The plant’s active ingredient safole, has been found to be carcinogenic. So investigate throughly before taking or using the plant for medicinal or eating purposes.

If you scrape away a little of the bark on a Sassafras tree, the wood underneath has an orange tinge.
