Wild onion is edible and is also favored by native-plant gardeners, who enjoy its showy umbels of pink flowers and tolerance of dry, rocky sites. This Ozark species blooms in summer and fall.

Smooth spiderwort is the most common and widely distributed of Missouri's spiderworts. It has slender, straight or zigzag stems. The long, narrow leaves are folded lengthwise and attach to the stem in a thick node. The 3 petals of the triangular flower are blue, rose, purple, lavender, or white.

“It’s an odd plant,” this rattlesnake master, “with its leaves like yucca, a head like a thistle, and second cousin to the carrot.” That’s how the great prairie writer John Madson summed it up!

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.

Dwarf spiderwort is a low-growing perennial with bright magenta, purple, or purplish-blue flowers with three petals arranged in a triangular pattern. It blooms in Ozark woodlands in April and May.

False garlic looks like a wild garlic or onion plant, but it doesn’t smell like one. The flowers can be white, yellowish, or greenish, and they appear in spring and sometimes also fall.

Star of Bethlehem is an introduced exotic plant that makes clusters of bright white flowers in the spring. It reproduces prolifically by forming a multitude of bulbs underground.

Whorled milkweed has rounded clusters of small white flowers. The leaves are soft, threadlike, and grow in whorls from the stem. It occurs in upland prairies and fields.

Slender mountain mint has smooth, square stems, opposite, narrow leaves, and dense heads of 2-lipped white (or lavender) flowers. Aromatic and minty, it can be grown at home in the herb garden, and its leaves used for seasoning food.
