Coreopsis

Asteraceae (Compositae)
Annuals, Perennials

Easy-to-grow members of the sunflower family yielding a profusion of yellow, orange, maroon, or reddish flowers. Deadhead for longer bloom; use hedge shears to remove large numbers of spent blooms. Both annual and perennial kinds are easy to propagate—annuals from seed sown in place or in pots, perennials from seed or division. Plants tend to self-sow; seeds attract birds.

The species listed here are from the eastern and southern U.S. unless otherwise noted.

Coreopsis grandiflora

Grows to 1–2 ft. high, spreading to 3 ft. Narrow dark green leaves with three to five lobes. Bright yellow, 2 1/2–3-in. single flowers bloom all summer, carried high above the foliage on long, slender stems.

Coreopsis lanceolata

Grows to 1–2 ft. high, 1–1 1/2 ft. wide. Narrow, somewhat hairy foliage, mostly in tufts near plant’s base; some leaves on lower part of flower stems have a few lobes. Yellow, 1 1/2–2-in. blossoms on pale green stems bloom in late spring and summer; make excellent cut flowers. When well established, persists year after year. Has naturalized in Hawaii.

Coreopsis maritima

Perennial. Native to coast of Southern California. Sometimes called sea dahlia. Grows from a tuberous taproot to reach 1–3 ft. high, 1–2 ft. wide. Stems are hollow; leaves are somewhat succulent, divided into very narrow lobes. True yellow, 2 1/2–4-in. blossoms on 9–12-in. stems in spring; make striking cut flowers. Use in borders, for naturalizing.

‘Limerock Ruby’

Tender perennial grown as an annual. Grows to about 1 1/2 ft. tall and 2 1/2 ft. wide; forms a clump of fine-textured foliage similar to that of C. verticillata. Ruby red flowers to 1 in. across appear in late spring through summer. Needs a bit more water than most other types of Coreopsis.

‘Nana’

Makes a 5–6-in.-high mat of 2–5-in.-long leaves. Under ideal conditions, it will spread by underground runners to form a 2-ft.-wide clump in a year. Bright orange-yellow, 1–2 1/2-in. flowers rise well above the foliage; blooms profusely over a long season (from spring to fall) if you deadhead faithfully. Best used in front of taller plants, in borders, or as edging.
