Field Guide

Common hackberry is named for its sweet, purple, edible fruits, but most people identify hackberry with its weird-looking bark, which develops numerous corky, wartlike projections and ridges.

Until Dutch elm disease came to America, the large, graceful American elm was widely planted along city streets and was beloved as the all-American shade tree. Now large specimens are rare, since the deadly fungus usually kills trees before they reach fine old ages.

Found nearly statewide, slippery elm has fuzzy twigs and reddish hairy buds, which often attract attention in wintertime. Its inner bark is reddish and rather slimy, which gives this tree its name "slippery."

Common alder is a good plant to know. The dried female catkins look like tiny pinecones.

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.

Swamp chestnut oak grows in Missouri's Bootheel swamps. The leaves look something like those of true chestnut trees.

“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.

In some parts of our nation, black willow is only a shrub, but in Missouri it grows quite large. The largest and most widely known of our native willows, black willow is the only member of its family that reaches commercial size.

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.
