Delphinium grandiflorum 'Delfix Blue'

Delphinium 'Delfix Blue', Chinese Delphinium 'Delfix Blue', Bouquet Delphinium 'Delfix Blue', Delfix Series


Delphinium grandiflorum 'Delfix Blue' is a low-growing, short-lived perennial with loose sprays of single, spurred, rich gentian-blue flowers. Blooming for weeks from early to late summer, this dwarf Delphinium forms a compact, bushy mound of well-branched, lacy green leaves. Compact, well-branched, it is perfect for edging, containers, or as a bedding plant.

  • Grows up to 12-15 in. tall (30-37 cm) and 6-8 in. wide (15-20 cm).
  • Performs best in full sun in fertile, medium moisture, well-drained soils.
  • Attractive to hummingbirds and butterflies, but ignored by deer and rabbits!
  • Perfect for beds and borders, edging, cottage gardens or rock gardens. For best visual impact, plant your Delphiniums in groups. Outstanding cut flowers.
  • These perennials tend to be short-lived and often start to lose their vigor after 2-3 years. Expect to replant them every few years or propagate new plants from basal cuttings of the original specimens. 'Summer Blues' may self-seed, particularly in cool-summer regions.
  • Deadhead spent flower spikes to encourage repeat blooming. After flowering, cut down all growth to ground level.
  • Propagate by taking pencil-thick basal cuttings in early spring or by division.
  • All parts of the plant may cause severe discomfort if ingested.
