Helianthus debilis (Beach Sunflower)

Beach Sunflower, Dune Sunflower, Cucumber-leaf Sunflower, Cucumberleaf Sunflower


A cheerful sight in the landscape, Helianthus debilis (Beach Sunflower) is a fast-growing perennial groundcover forming a lush mound of semi-evergreen, dark green, deltoid leaves, 4 in. long (10 cm), that are irregularly lobed and toothed. They offer a perfect backdrop for the small, sunflower-like flowers, 3 in. across (7 cm). Blooming from spring to fall, continuously in frost-free areas, each charming flower is adorned with 10-20 yellow rays that surround a purplish-brown disk. They are particularly attractive to bees, butterflies and birds. Beach Sunflower spreads quickly by runners, making it a terrific groundcover. In areas with freezing winter temperatures, it may die back to the ground. However, Beach Sunflower is a prolific self-seeder and many new plants will appear in the spring. Undemanding, salt and drought tolerant, this attractive wildflower is a plant of choice for beachside locations. It is also useful in mass plantings, edging, cascading down a wall or container. Beach Sunflower helps stabilize dunes and sandy soils thanks to its taproot and numerous lateral roots. Florists enjoy its lovely cut flowers.

  • Typically grows up to 18-24 in. tall (45-60 cm) and 24-48 in. wide (60-120 cm).
  • Prefers full sun in acidic, sandy, well-drained soils. Drought and salt tolerant once established. Be careful not to over-water this plant.
  • Fertilize once a year - in spring and late summer until the plant is established.
  • Low maintenance, this is an excellent choice for butterfly gardens, wildflower gardens or coastal gardens. Great for cascading down a wall or containers.
  • No serious pest or disease issues.
  • Prune in spring. Cut back to promote new full growth.
  • Propagate by non stratified seed in late fall or after the last frost in northern areas. Can be propagated by softwood cuttings
  • Native to the coastal areas from North Carolina to Florida and Texas.
