Because each plant disperses a large number of seeds, garlic mustard can outcompete native vegetation for light, moisture, nutrients, soil, and space as it quickly colonizes an area.

Our most widely distributed early spring flower, spring beauty has 5 white or pink petals with distinct pink veining, and 5 pink anthers. The narrow, bladelike leaves are fleshy. These flowers often grow in abundance, covering a patch of ground with the beauty of spring.

Tall thistle is a native thistle that can grow to be 10 feet tall! To identify it, notice its leaves, which are unlobed (though they may be wavy or have only shallow, broad lobes), are felty-hairy beneath, and have prickles only along the edges.

Solomon's seal grows statewide in moist, rich earth. The greenish-white flowers dangle like little bells beneath the leaves, under the gracefully arching stems.

Arrowheads are aquatic plants with erect, usually arrow-shaped leaves and distinctive three-petaled flowers. They are often called duck potatoes because ducks, geese, and swans relish the tuberlike rootstocks.

Like many of its relatives in the mustard family, spring cress has a bitter or pungent flavor, similar to horseradish. It is sometimes used as a condiment and in salads. Or you could just enjoy the pretty white flowers!

Next time you breeze past weedy black mustard on the highway or spot it in a fallow field, think of how important this and other mustards are to the world economy – and to your dinner table.

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.

Missouri has two species of sweet cicely, which can be hard to tell apart. Both have umbels of small white flowers, fernlike leaves, and sweetly aromatic, carrotlike roots.
