Delphinium Pacific Giants Black Knight Hardy Perennial Plants, Tall Cottage Garden Flowers, Outdoor Garden Ready, 1 Litre Root-Ball

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.
