Lanceleaf coreopsis

A clump-forming native milkweed with bright orange summer flowers, strong pollinator value, and tolerance for dry sunny sites.

A low, clump-forming native woodland violet of eastern North America, grown for its early spring blue-to-purple flowers with conspicuous white throats held over glossy, heart-shaped leaves. It does not run, but self-seeds freely - to the point of being weedy in rich, moist ground. A larval host for fritillary butterflies and a nectar source for early bees and butterflies; the leaves are high in vitamins A and C.

The original black-eyed Susan - a bristly-stemmed, short-lived meadow daisy that behaves as an annual, biennial, or brief perennial depending on where it grows. It blooms hard and early from seed, then carries itself forward by reseeding rather than by spreading into a permanent clump.

A native upright perennial with fragrant midsummer flower panicles in pink, white, lavender, or red - a classic border anchor and hummingbird-friendly choice for sunny beds.

Largeflower tickseed is sold as a perennial and behaves like one for about two years. Missouri Botanical Garden says plainly that the plants are somewhat short-lived and that self-seeding is what perpetuates a good planting; the Lady Bird Johnson Wildflower Center is blunter still, recording that it is not reliably perennial and self-sows readily, becoming weedy. Those are two descriptions of the same plant, and believing them is the whole difference between a stand that lasts and an expensive annual. What you are buying is a seed-perpetuated colony rather than a long-lived clump: the original crowns thin out after two or three seasons and volunteers carry the planting on, which means it survives only where there is bare soil to germinate in and where some flowers are allowed to set seed. Deadhead every head, every year, and the colony ends when the crowns do. The flowers are the largest of the common yellow tickseeds, 2 to 3 inches across, deep yellow rays notched at the tips around a darker golden disc, held one to a stem on slender erect stalks to about 24 inches. What it wants is the opposite of border hospitality: poor sandy or rocky soil with sharp drainage, full sun, and no irrigation. Missouri Botanical Garden records it as tolerant of heat, humidity and drought and names crown rot in moist, poorly drained soil as the way it dies, so the reliable method of killing it is kindness. Within this catalog it sits between plains coreopsis (Coreopsis tinctoria), a true annual that never pretends otherwise, and lanceleaf coreopsis (Coreopsis lanceolata), the other short-lived perennial and the plant it is most often mislabelled as. The leaves settle it: lanceleaf carries narrow, hairy, unlobed lance-shaped leaves gathered in a basal tuft, while largeflower has lobeless linear leaves at the base and pinnatifid, deeply lobed upper leaves cut into linear segments up the stem.

A tough, bright perennial for sunny borders, pollinator patches, and late-summer color.
