The lowest prices online Delphinium Pacific Black Knight

Tell Me More…
When restraint and subtlety just won’t do, a big, beefy delphinium such as ‘Pacific Black Knight’ can be just the thing. This statuesque plant produces flower spikes up to 1.75m tall, each densely packed with semi-double, deep purple, black-eyed flowers. The moment for these is early summer, though second flush of flowering is possible if spent flower spikes are removed straight away.’Pacific Black Knight’ is at its most effective grown in groups, creating a bold, dense, almost forest-like swathe of colour. We love seeing a drift of this towards the back of a mixed border, perhaps with a shrub rose, opium poppies and lupins nearby. Like all delphiniums it will benefit from fortnightly feeding throughout the growing season, particularly if there is to be further flowering. For best results plant in fertile, moist, well-drained soil in full sun, with staked support and shelter from strong, cold winds. ‘Pacific Black Knight’ is hardy to between -10 C and -15 C. As a short-lived perennial it is often treated as an annual or biennial, though with care and attention can be kept going for longer. H: 1.75m S: 1m.
