American holly is Missouri's most durable broad-leafed evergreen tree. It is best known for its bright red berries and spiny green leaves at Christmas.

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.

The white, smooth-looking limbs of sycamore rise over countless streams and river banks, as well as over sidewalks and city streets. The leaves, which somewhat resemble those of maples, can reach remarkably large sizes.

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.

You might see common buckthorn for sale at a nursery, but don’t buy it! At least six states have banned this invasive exotic, and the difficult-to-control plant is causing problems here in Missouri, too. Learn how to identify it — and avoid it!

Of the three species of catalpas in our state, northern catalpa is the only one native to Missouri (specifically, the Bootheel region). It has been planted widely, though, and has naturalized in many places. A popular ornamental and shade tree with pretty, orchidlike flowers and long, beanlike fruit.

Arrowwood viburnum is a lovely but critically imperiled Missouri shrub, but the white flower clusters and dark blue berries make it a great choice for landscaping.

Nannyberry is an understory shrub or small tree that grows in low woods, wooded slopes, and rich valleys near streams. It is officially a Species of Conservation Concern in our state, but its rarity here may be because Missouri is at the southern end of its range.

A very small shrub of our native prairies and other open sites, New Jersey tea was used by patriotic American colonists as a substitute for black tea imported from England during the Revolutionary War.
