Obedient plant is a clump-forming native perennial that grows aggressively. From midsummer to early fall, spikes of purple or pink (and sometimes white) flowers rise above sharply toothed leaves to four feet high.

This terrestrial orchid has 3 to 7 oval to lance-shaped leaves. Unusual flowers almost 4 inches long, with a rose-pink floral globe under a pair of twisted petals, are borne singly or in pairs on upright stems in summer.

This is one of the smallest species of goldenrod, topping out at only 4 to 6 inches high in poor soils, and 2 feet high in fertile soils. It is considered a garden-worthy species, with gray-green leaves that form clumps and languid, one-sided yellow plumes. It is tolerant of both sandy and clay soils.

Moss phlox is a dense ground cover blanketed with notch-petaled flowers in April and May. Blooms can be muddy hot pink, bright rose, and magenta, while other cultivars include white, soft lavender-blue, clear pale pink to deep pink, clear scarlet, and lavender, some with a darker or lighter eye. Evergreen foliage is narrow, short, and stiff. Darker-flowered forms have dark-green leaves or red-tinged leaves that darken to burgundy in winter.
