Field Guide

Lamb’s quarters won’t win any beauty contests for its flowers, but it merits an award for being both a common garden weed as well as a nutritious leafy green valued around the world.

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.

Common ragweed is instantly recognizable by its ornate, 2–3 times pinnately lobed, hairy leaves. You’ve probably seen it many times and wondered what it was.

Missouri boasts nine native species of blazing stars, or gayfeathers, in genus Liatris. These showy, upright, unbranching spikes of magenta-pink wildflowers bloom in sunny habitats.

Cylindrical blazing star is one of several Missouri native species of blazing stars, or gayfeathers. It is widely scattered in the Ozarks and eastern Missouri. Identify it by its bracts, which are pressed against the base of the flowerhead, accentuating its cylindrical look.

Scaly blazing star is one of several Missouri native species of blazing stars, or gayfeathers. It is scattered nearly statewide. Identify it by its long-pointed flowerhead bracts that spread or curl sharply away.

Blue sage is easily identified by its wandlike clusters of sky-blue, two-lipped wildflowers. It blooms July–September in prairies, roadsides, and other open habitats.

Swamp agrimony has wandlike clusters of tiny yellow flowers atop its stout, upright stems. Its feather-compound leaves have up to 23 narrow, sharp-toothed main leaflets, plus smaller leaflets between the main ones.

Virginia knotweed, or jumpseed, is common yet rarely contemplated. It might be most eye-catching in spring, when its new, oval leaves are marked with brownish Vs. In summer, it blooms with tiny, teardrop-shaped white flowers on wandlike stems.
