Hunky Dory™ White Delphinium

Hunky Dory™ White is the white-flowered code 70098109 selection in Syngenta’s upright Delphinium grandiflorum series. Its product page lists full sun, pollinator appeal, flowering from late spring through fall, a height of 16–24 inches, a spread of 10–12 inches, and hardiness zones 4a–9b. [Syngenta’s Hunky Dory White profile](https://www.syngentaflowers.com/ams/product/flower/70098109) identifies the exact color and code. ## In the garden Use the compact white flowers to brighten a sunny border or a roomy container, alone or alongside the blue Hunky Dory selections. The breeder describes the series as vigorous and uniform in flowering. Give plants a sunny position and fertile soil that drains freely; the species is generally grown as an annual or short-lived perennial, so longevity varies with climate and site. ## Maintenance Water while plants establish and through dry spells, but avoid waterlogged roots. Deadhead faded stems to keep the display tidy, then cut plants back after flowering. The [RHS species guidance](https://www.rhs.org.uk/plants/5399/delphinium-grandiflorum/details) recommends full sun, fertile well-drained soil, deadheading, and cutting back after flowering. Syngenta lists zones 4a–9b for this named selection; use that range as a guide rather than a guarantee for every garden.
