Field Guide

Sweet autumn virgin’s bower, also called autumn clematis, is a nonnative, invasive perennial vine that spreads aggressively and climbs rapidly over any support. In late summer, it produces dense clusters of white, sweet-smelling flowers, which mature into fuzzy seed masses.

Dodders are easy to identify, even though at first you might not recognize them as plants. These parasitic plants usually look like a hairlike mass of yellow or orange, leafless, wiry, vining stems wrapping around the stems of other plants.

Prairie dogtooth violet, or prairie trout lily, is a small, early blooming lily that lives in prairies and glades. Its flowers are white and its narrow leaves are folded lengthwise and seem waxy on the undersurface.

Common chickweed, native to Europe, has been introduced nearly worldwide and is a familiar garden weed in Missouri. It forms spreading mats on the ground and has small flowers with 5 petals, each deeply lobed making it look like 10.

Mud plantains have glossy, rounded or kidney-shaped leaves and purple or white flowers that have six petal lobes. One petal lobe points downward. They typically grow as emergent aquatic shoreline plants.

Dame’s rocket has showy clusters of purple flowers that bloom atop waist-high stalks in April, May, and June. A native of Eurasia, this member of the mustard family was introduced as a garden flower. It commonly escapes from cultivation.

Downy phlox, also called prairie phlox, is a perennial wildflower with lance-shaped leaves and showy, rounded clusters of pink or lavender flowers. It is similar to blue phlox, but it grows more often in prairies and other open, sunny, and drier habitats.

In Missouri, crested iris occurs naturally only in our southeastern counties. If you’re already familiar with irises, this is an easy identification: in addition to the distinctive color pattern, this iris does not exceed 12 inches in height, and the sepals (“falls”) have conspicuous, bumpy crests.
