Kniphofia ‘Royal Castle Hybrids’ – Bold Summer Colour with Classic Red Hot Poker Form
Kniphofia ‘Royal Castle Hybrids’ is a striking and reliable mix of classic red hot pokers, prized for their tall, dramatic flower spikes and strong architectural presence. Flowering through summer, each plant produces bold torch-like blooms in rich shades of red, orange, and yellow, creating a vibrant, eye-catching display that brings height and energy to mixed borders.
The flowers rise confidently above robust clumps of narrow, grassy green foliage, adding both structure and movement to planting schemes. Their nectar-rich blooms are highly attractive to bees and other pollinators, making them an excellent choice for wildlife-friendly gardens as well as traditional and contemporary borders.
Hardy, vigorous, and easy to grow, ‘Royal Castle Hybrids’ thrive in full sun and free-draining soil, coping well with heat and dry conditions once established. Their taller habit makes them ideal for the middle or back of borders, where they can be used as bold focal points or planted in drifts for maximum impact.
