The compact dimensions make it suitable for the front or middle of a mixed planting, where the light-blue flowers can be viewed closely. The series is described as vigorous and uniform in flowering, but garden performance and bloom timing vary with climate and care. ## Maintenance Water during establishment and during extended dry periods, allowing excess water to drain away. Remove spent flower stems to tidy the plant. Delphinium grandiflorum is often grown as an annual or short-lived perennial; the [RHS species profile](https://www.rhs.org.uk/plants/5399/delphinium-grandiflorum/details) describes full sun, fertile well-drained soil, and cutting plants back after flowering. Use the breeder’s listed zone range as a guide, since winter survival also depends on drainage and local conditions.
