Delphinium 'Galahad'

Delphinium 'Galahad' is a classic tall border delphinium producing stately spires of pure white flowers in early summer, bringing height and brightness to mixed and cottage borders. In Irish gardens it performs best in full sun and a fertile, moist but well‑drained soil, with shelter from strong winds; stake developing stems and deadhead after the first display to encourage a later flush. Deciduous clumps carry fresh green, deeply divided foliage, and the dramatic blooms are excellent for cutting.

To help give a clear sense of scale, the stone wall shown in our photos measures approximately 265cm in height. We also use familiar garden tools as visual references: a digging fork (110cm tall) and a hand fork (30cm tall). These are included purely as size guides to help you better judge proportions when viewing the images.
