Easy to grow in any well-drained soil. Tolerates dry sites and is suitable for perennial border, naturalizing or rock gardens. Also effective in native plant gardens or cottage gardens. Good plant for areas with poor, dry soils.

General Information +

Botanical: Coreopsis verticillata 'Zagreb'

Common: Threadleaf coreopsis

Family: Asteraceae

General Characteristics: Threadleaf coreopsis (also commonly called whorled coreopsis) is a rhizomatous perennial which typically grows in dense, bushy clumps to 1-3' tall. 'Moonbeam' is somewhat more compact (to 2' tall) and features pale yellow, daisy-like flowers (1-2" diameter) with untoothed rays and darker yellow center disks. Flowers appear singly in loose clusters (cymes) in a lengthy late spring to late summer bloom period which sometimes extends to first frost. Shearing plants in mid-summer (early August) when bloom usually tapers down will encourage a fall rebloom.

Planting/Care Instructions +

Pests or Diseases: No serious insect or disease problems.

Planting Instructions: Dig a hole large enough to encompass the roots without bending or circling. Set the plant in place so the crown (part of the plant where the root meets the stem) is about 1-2 inches below the soil surface. Cover with soil to the original soil surface and water thoroughly. Easily grown in dry to medium wet, well-drained soil in full sun. Thrives in poor, sandy or rocky soils with good drainage. Tolerant of heat, humidity and drought. Prompt deadheading of spent flower stalks can be tedious for a large planting, but does tend to encourage additional bloom. Plants may be sheared in mid to late summer to promote a fall rebloom and to remove any sprawling or unkempt foliage. Although species' plants freely self-seed, 'Moonbeam' is a sterile cultivar. Plants can spread somewhat invasively in the garden by rhizomes.
