Field Guide

You may not recognize elephant’s foot as a member of the daisy or sunflower family because it lacks petal-like ray florets. Also, it has unusual, doubly compound flower clusters. And how did it get its name, anyway?

Ox-eye daisy, though familiar, is not native to North America. It was introduced long ago from Eurasia. Common in grassy uplands, pastures, fencerows, and roadsides, it can colonize aggressively in the garden.

Our weediest sneezeweed, bitterweed arrived in Missouri in the late 1800s from its home range in Texas and Louisiana. Like our other heleniums, it has domed disks and yellow, fan-shaped, notched ray florets. Unlike them, the leaves are narrowly linear.

Native to Ozark glades and prairies, tickseed coreopsis has long been appreciated as a hardy garden perennial. Because of its popularity, it has escaped from cultivation and now occurs statewide.

White heath aster is one of Missouri's most widespread and weedy native asters. It grows in uplands, bottomlands, and nearly all habitats in between. It has a shrubby, wide-branching habit, and the stem leaves are thin and needlelike.

The scarlet pimpernel, a native of Europe, is a tender annual with scarlet or brick-red flowers that close around 4 p.m., or whenever clouds shade the sun. When the sun comes out again, they reopen.

Named for its resemblance to a European herb that was popular in Medieval times, golden Alexanders is a native Missouri wildflower with bright yellow flowers arranged in umbrella-like clusters.

Queen Anne’s lace is many things to many people — roadside wildflower, noxious introduced weed, wild edible, medicinal herb, delightful cut flower. In Missouri, it blooms May through October.

Full grown, water hemlock looks something like a gigantic Queen Anne's lace, but this common, widespread member of the carrot family is the most toxic plant in North America. All parts are deadly. A piece of root the size of a walnut can kill a cow-sized animal.

Water smartweed can live submerged in water, or on wet banks or other soggy ground, yet it can also live in merely moist areas. The stems often sprawl as they grow, taking root at the swollen nodes. The small, pink flowers develop in long, erect clusters.
