Kniphofia 'Fire Glow'

Fire Glow Red Hot Poker

Kniphofia 'Fire Glow' is a perennial plant known for its tall, flower spikes that feature tubular flowers of yellow, transitioning to deep orange. Blooming from early to late summer, the flowers gradually shift in color, creating a fiery gradient that adds warmth to the garden. The plant's dense clusters of flowers rise above its sword-like, arching leaves, creating an eye-catching vertical element that works well in borders, cottage gardens, and as a focal point in containers.

Design tip

Use it as a steady framework plant, repeating it along a bed to tie separate plantings together. In full sun it holds its shape best, and grouping several together keeps the color strong enough to be seen from across the garden.
