Dahlia 'Gallery Art Nouveau'

Gallery Art Nouveau Dahlia, Decorative Dahlias, Gallery Series


Award-winning Dahlia 'Gallery Art Nouveau' is a wonderful dwarf bedding Dahlia with profuse, vibrant purple-lilac flowers, 4-5 in. across (10-12 cm), with slightly twisted petals which expose their deeper purple undersides. They stand out against the dark green foliage. Blooming massively from midsummer to frost, this particularly compact and floriferous dahlia grows up to 16 in. (40 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 Decorative Dahlias. These are double dahlias with broad, flat-tipped petals that are sometimes wavy. The flowers are normally large and the plants easily top 40 inches tall, although there are even taller varieties. They can be formal with flat petals evenly and regularly placed throughout the flowers, or informal with generally flat petals, sometimes slightly rolled at the tips, but with irregular arrangement of formation. They are all real eye-catchers!
