Field Guide

Many Missouri children learn about this orange-flowered native plant by playing with the juicy green seedpods, which, when ripe, "explode" upon the slightest touch. This is jewelweed's mechanism for seed dispersal, and it's the reason for the name "touch-me-not."

Our two Missouri jewelweeds occur in the same habitats, often side by side, and even botanists can’t tell them apart without the flowers. Pale touch-me-not is the one with the lemon-yellow flowers!

The showy, bright yellow flowers of celandine poppy really stand out in the shady woods and valleys where this plant grows. You should consider this species when you are planting a shade garden!

The smooth, finely divided, fernlike foliage of pale corydalis is similar to that of the related wildflower Dutchman’s breeches. But in pale corydalis, the small yellow flowers appear tubelike and lipped.

These two species of sweet clover are present all over America. Although they have been planted for forage, as bee plants, and as nitrogen-fixers, white and yellow sweet clover are now classified as invasive for their weediness and the problems they pose for natural habitats.

Common cinquefoil, or five-finger, is named for its leaves, which are divided into five fingerlike leaflets. One of seven cinquefoils in Missouri, it blooms from April to June and is scattered nearly statewide.

Of the many invasive nonnative plants that were originally introduced to stop soil erosion and improve soils, kudzu is one of the worst. This “vine that ate the South” is often the first plant that comes to mind when we think of “invasive plants.”

A bushy native perennial legume with small clusters of pink flowers, slender bush clover provides nectar for numerous insects. Several types of birds eat the seeds, and many mammals eat the foliage.

There are 23 species of goldenrods in Missouri. They can be hard to identify to species, but as a group, the goldenrods are common and nearly unmistakable.

The flowers of southern wild senna don’t look much like typical pea-family flowers, but its leaves and bean pods show the family resemblance. Look for it in moist situations, mostly south of the Missouri River.
