With a glorious deep bronze foliage set against masses of fiery red flowers, adorned with a small golden-yellow ring surrounding their chocolate-brown centers, Dahlia ‘Happy Single Flame’ is a particularly striking Dahlia. The single flowers, up to 4 in. wide (9 cm), blend nicely with other plants and add welcomed color and form to the late season garden. Blooming massively from midsummer until Frost, this dahlia grows up to 28 inches (70 cm) and is an excellent choice for beds and borders, patio, deck, or balcony.

  • Recipient of the prestigious Award of Garden Merit of the Royal Horticultural Society.
  • Best flowering occurs in full sun, but light shade will be welcomed in hot summer areas.
  • Provide consistent moisture during the growing season and do not allow soils dry out. Plant in a sheltered location to protect your dahlias from strong winds.
  • Best in groups of 5 for best visual effect. Deadhead spent flowers to promote growth of additional flower buds.
  • Toxic to dogs, toxic to cats, toxic to horses.
  • If you live in a cool area (hardiness zones 3-7) and you want to save your dahlia bulbs, or more precisely, your dahlia tubers for next spring, you may dig them up before the first frost and store them over winter before replanting them next spring. Store them in boxes, covered with moistened sand in a cool, dark, frost-free place where temperature remains between 45-50 °F (7-10°C).
  • This Dahlia is a member of the Single-Flowered Dahlias which feature blooms with a single row of flat or slightly cupped ray florets arranged in a flat plane, uniformly overlapping, preferably in the same direction with no gaps. Disc flowers may have up to three rows of pollen and the bloom is over two inches in diameter.
