Description from Crocus
Tall bright and imposing, kniphofias lend height, vibrancy and drama to any garden. 'Royal Standard' produces spikes of bright yellow tubular flowers, scarlet in bud, above clumps of evergreen, strap-like leaves. Originally from South Africa, the elegant, torch-like flowers of kniphofia make vertical accents in a sunny border and look particularly good as part of a scheme based on 'hot' colours. They also look great with a background of ornamental grasses. An easy and undemanding plant.
