Delphinium 3L

Delphiniums are classic cottage-garden perennials prized for their tall, elegant flower spires in early to midsummer, ideal for the back of sunny borders in Irish gardens. Grow in fertile, moisture‑retentive but well‑drained soil in full sun, with shelter from strong winds; stake the hollow stems early and deadhead after the first flush to encourage further blooms. Apply a spring mulch and regular feeding for best performance, water in dry spells, and protect young shoots from slugs and snails.

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.
