Set of 3 or 6 Delphinium Pacific Giants Black Knight Hardy Perennial Plants, Tall Cottage Garden Flowers, Outdoor Garden Ready, 1 Litre Root-Ball
£20.99
Unit price / perEstimated delivery between June 15 and June 17.
Add height and drama to your garden with this stunning Delphinium Pacific Giants 'Black Knight'. Renowned for its towering spires of deep violet-blue, semi-double flowers with contrasting dark centres (known as the \"bee\"), Black Knight is one of the most striking varieties in the celebrated Pacific Giants series. These garden-ready plants are supplied as a set of three in 1Ltr root-balls, well-established and ready to plant straight into borders or containers.
A classic cottage garden favourite, Delphinium 'Black Knight' produces magnificent, densely packed flower spikes that create a bold vertical accent in herbaceous borders and mixed plantings. The rich, dark blooms are highly valued for cut flower arrangements and are a magnet for bees and other pollinating insects. As a fully hardy herbaceous perennial, it will die back over winter and return reliably each spring with vigorous new growth.

- Prefers full sun but will tolerate light partial shade
- Stake tall flower spikes to protect them from wind damage

- Apply a mulch of well-rotted compost in spring to encourage strong growth
- Water regularly during dry spells, particularly while establishing
