Field Guide

“Way down yonder in the pawpaw patch” is an old song you might be familiar with — but today, surprisingly few Missourians know a pawpaw tree when they see one. This is a good tree to know, especially when the large, sweet fruit are ripening!

Osage orange is a densely branched, short-trunked, thorny tree. It bears weird-loooking, softball-sized, chartreuse, brainlike fruits, which often lie beneath the tree in abundance in autumn.

Willow oak's leaves are narrow, pointed, and willowlike, and like willows, this oak is associated with wet ground. In Missouri, willow oak is only found natively in our southeastern counties.

Don’t kid yourself about this invasive, exotic vine: Japanese honeysuckle is an aggressive colonizer that shades out native plants and harms natural communities. Learn how to recognize it!

Introduced from Asia as a groundcover, wintercreeper has escaped cultivation in all the eastern states. It’s frequently found near urban centers, with heavy infestations in woodlands around St. Louis and Kansas City.

Shingle oak got its name because the naturalist who discovered it noticed that French colonists in Illinois were using the wood to make roofing shingles. The leaves resemble those of laurel (bay), lacking lobes or teeth — but laurel trees don't bear acorns!

Corkwood is a rare and unusual small tree that doesn’t have a problem with having its feet wet for long periods of time, but it grows rarer as its swampy habitat is converted to cropland.

Dogwoods usually have leaves arranged opposite one another on the stem, except for the alternate-leaved dogwood! This shrub or small tree is a popular ornamental, especially in the northern parts of Missouri, where it can be too cold to grow flowering dogwood.
