Hunky Dory™ Blue Delphinium

Hunky Dory™ Blue is an upright, blue-flowered Delphinium grandiflorum selection in Syngenta’s Hunky Dory series. Its breeder profile describes uniform flowering, full-sun culture, pollinator appeal, and a 16–24 inch height by 10–12 inch spread, with hardiness listed for zones 4a–9b. The exact product is identified as code 70092103 on [Syngenta’s Hunky Dory Blue page](https://www.syngentaflowers.com/ams/product/flower/70092103). ## In the garden Use this compact selection in a sunny border, a large container, or a grouped planting where its blue flowers can be seen up close. The series is described as upright and vigorous, with flowering across late spring, summer, and fall; actual timing depends on local conditions. Full sun is the breeder’s stated exposure. Choose a fertile, well-drained site and give plants room for air movement. ## Maintenance Keep soil evenly moist while plants establish, then water when the root zone begins to dry; avoid persistently soggy soil. Remove faded flower stems to keep the planting neat. Delphinium grandiflorum is generally treated as a short-lived perennial or annual, and the [RHS species profile](https://www.rhs.org.uk/plants/5399/delphinium-grandiflorum/details) recommends sun, fertile well-drained soil, deadheading, and cutting back after flowering. This is practical species-level guidance, while the color, size, and zone details above come from the named Hunky Dory product.
