Field Guide

Poison ivy is a toxic plant that contains an oil in all its parts that, if you come into contact with it, can cause an intense skin reaction. Learn to recognize it, and sidestep it on your outings.

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.

Starting more than a century ago, this nonnative rose was planted across America — for many good reasons — but multiflora rose has proven to be invasive, and now the goal is to stop its spread.

Also called climbing rose, prairie rose is most common near woodlands, where it climbs and trails on neighboring shrubs and small trees.

Golden rain tree is native to China, Korea, and Japan. It was cultivated in Missouri for years. Because it readily escapes from cultivation and is invasive, it is no longer recommended for planting in Missouri.

Grown as an ornamental for its attractive pink flower clusters, gracefully spreading branches, and delicate leaves, mimosa is easily propagated and grows rapidly. Unfortunately, it is also an invasive exotic in much of the state.

Colonies of smooth sumac are most noticeable in early autumn, because the leaves turn brilliant red! You can make drinks and jellies from the clusters of fuzzy red berries.

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.
