Hawthorns
Various species in the genus Crataegus
Our state flower, the hawthorn, is solidly represented in Missouri. There are about 100 different kinds of hawthorns that occupy almost every kind of soil in every part of the state. These members of the rose family are closely related to apples.

Willows
Salix spp. (about 12 species in Missouri)
Exotic willows are available at lawn and garden centers, but there are several willow species that are native to Missouri. Most are rather humble colonizers of gravel bars, riverbanks, and lakesides. Many are important for human economic interests. All have a place in our wild ecosystems.

Sandbar Willow
Salix interior (formerly S. exigua)
Identify sandbar willow by its very narrow leaves with widely spaced, slender teeth along the margins. This is a good soil binder and bank stabilizer; it prevents washing and erosion of alluvial soil.

Swamp Privet
Forestiera acuminata
Swamp privet is a straggly shrub or small tree growing in wet to swampy ground. It is quite noticeable in early spring, with the clusters of yellow flowers and bracts appearing along the gray branches before the leaves come out. In this way, it is similar in aspect to spicebush.

Giant Cane
Arundinaria gigantea
Giant cane is Missouri’s native species of bamboo. It is scattered mostly in our southernmost counties and the Bootheel. In its low, moist habitats, it sometimes forms canebrakes — dense, nearly pure thickets.

About Trees, Shrubs and Woody Vines in Missouri

There are no sharp dividing lines between trees, shrubs, and woody vines, or even between woody and nonwoody plants. “Wood” is a type of tissue made of cellulose and lignin that many plants develop as they mature — whether they are “woody” or not. Trees are woody plants over 13 feet tall with a single trunk. Shrubs are less than 13 feet tall, with multiple stems. Vines require support or else sprawl over the ground.
