Vigorous, award-winning Delphinium ‘Jill Curley’ (Candle Larkspur) is a tall, clump-forming, herbaceous perennial with spectacular spikes of extra large, 3 in. across (8 cm), semi-double, white flowers with a creamy-white eye. Blooming for weeks from early to midsummer, this striking Delphinium hybrid adds a wonderful architectural presence in the garden and draws attention from quite a distance. Rising from a low mound of deeply lobed, glossy, dark green leaves, it is ideal at the back of a mixed border or as a centerpiece to an island flower bed for a vertical accent. Splendid in cottage gardens.

  • Recipient of the prestigious Award of Garden Merit of the Royal Horticultural Society.
  • Grows up to 5-7 ft. tall (150-210 cm) and 1-2 ft. wide (30-60 cm). Will require staking.
  • Performs best in full sun in fertile, medium moisture, well-drained soils. Provide a sheltered location to protect your plants from strong winds.
  • Attractive to hummingbirds and butterflies, but ignored by deer and rabbits!
  • A welcomed addition to beds and borders, cottage gardens, or city gardens. For the best visual impact, plant your Delphiniums in groups. Excellent as cut flowers, they deserve a spot in your cutting garden.
  • Deadhead by cutting spent flower spikes back to small flowering side shoots. Cut down all growth to ground level after it has withered in autumn.
  • Apply a balanced liquid every couple of weeks in the growing season. For best flower spikes thin shoots when 7cm high to leave a minimum of 2-3 shoots on young plants and 5-7 shoots on established plants.
  • Propagate by taking pencil thick basal cuttings in early spring.
  • Keep an eye out for slugs, snails, leaf miners, caterpillars, powdery mildew, and crown rot.
  • All parts of the plant may cause severe discomfort if ingested.
  • Toxic to dogs, toxic to cats, toxic to horses. Poisoning is rare in humans, however, seeds and plants if ingested can lead to severe illness, paralysis, and even death.
