The dwarf chestnut oak, though only 3–10 feet tall and the shortest of Missouri's oaks, can nevertheless produce abundant acorns that are relished by several types of birds and mammals.

Persimmon is best known in the fall, when its orange, plumlike fruits come on. Be careful, however, to make sure a persimmon is ripe before you pop it into your mouth, or you could have a puckery surprise!

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.

A clumped shrub that grows naturally only in the northeastern part of Missouri, meadow willow lives in low, wet ground in mud or sandy gravel along streams and in wet meadows. Rare in our state, it is perhaps best identified by examining the leaves.

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!

Occasionally confused with poison ivy, Virginia creeper is easily identified by simply noticing that most of its leaflets are in fives, instead of threes. This common native vine is useful in landscaping.

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!

American hazelnut is a thicket-forming shrub that grows to about 10 feet high. It is prized for its edible nuts, which are covered by a distinctive leafy or papery, jagged-edged bract.

Winged sumac is most common south of the Missouri River. The "wings" in the name refer to the narrow, flattened leafy structures running along the central stems of the compound leaves.
