Heliopsis helianthoides (False Sunflower)

Smooth Oxeye, Oxeye Sunflower, False Sunflower


Heliopsis helianthoides (False Sunflower) is a showy short-lived perennial forming upright clumps of stiff, branched stems boasting sunflower-like flowers, 2-3 in. across (5-7 cm) from early summer to fall. Resembling small sunflowers, each blossom features yellow-orange rays surrounding cone-shaped brownish-yellow center disks. They are visited by bees, butterflies and other pollinating insects. The stems are clothed in pairs of opposite, ovate, toothed leaves, 6 in. long (15 cm). A valuable addition to the landscape with its profusion of bright glowing daisies over a long season, False Sunflower is an undemanding plant which provides excellent, mid-summer color. Hardy and easy to grow, it is a beautiful garden perennial for dry sites.

  • Grows up to 3-6 ft. tall (90-180 cm) and 2-4 ft. wide (60-120 cm).
  • Performs best in full sun in average, dry to medium, well-drained soils. This plant is not fussy about soils and tolerates a wide range of soil conditions, including poor soils, dry soils and clay soils. Light shade is also tolerated, although the plants might tend to flop and hence will require some support. Drought tolerant once established.
  • Excellent choice for perennial borders where their dazzling flowers are welcomed in any color scheme. Perfectly suited to the cutting garden, naturalized plantings.
  • Deadhead spent flowers to promote new blooms. Cut back after flowering.
  • No serious pest or disease issues. Keep an eye out for aphids.
  • Propagate by seed in fall or early spring. Large clumps can be divided, but it is fairly difficult.
  • Native to central and eastern North America.
