Flaming torches in midsummer. Red hot poker, also known as kniphofia or African lily, produces metre-high, leafless stems topped with dense spikes of tubular flowers—red at the top and yellow toward the bottom, like a lit torch. An exotic-looking perennial that, with light winter protection, returns year after year in the garden.

What makes this variety stand out
Kniphofia uvaria comes from South Africa, and this is evident in its form: a clump of long, narrow, grass-like leaves, above which rise stiff stems with flower heads resembling flames. The buds are intensely red or orange, while the flowers turn yellow from the bottom as they open, giving the spike a natural two-coloured gradient. Flowering lasts for many weeks, and a single mature clump can produce a dozen or more stems.
Plants grown from seed usually flower in the second year, sometimes the third, and become more impressive with each season. Red hot poker is long-lived and, in a good location—warm and sunny, with well-drained soil—grows in the same clump for many years. The flowers are eagerly visited by bumblebees and butterflies.
Growing step by step
Sowing (April–June, under cover): sow the seeds in trays filled with a light, well-drained growing medium, covering them with a layer of about 3 mm. At 18–22°C, germination occurs unevenly over 2–3 weeks; do not discard the sowing too soon, as some seeds need more time.
Pricking out: prick out seedlings with 2–3 leaves into 10 cm pots, where they will remain until spring. In summer, the pots can be placed outdoors in the sun, but during their first winter young red hot pokers should be kept in a cool, bright, frost-free room (e.g. 3–8°C) and watered very sparingly.
Planting out (April–May of the second year): plant the seedlings, keeping the entire root ball intact, in their permanent position at a spacing of approx. 40 × 50 cm, in fertile but necessarily well-drained soil and full sun. On heavy soils, add sand or fine gravel to the planting hole.
Care: water during drought and fertilise in spring. Cut faded stems back at the base. Before winter, tie the leaves into a loose bundle (this protects the plant’s crown from water) and cover the clump with a thick layer of dry leaves or conifer branches; remove the covering in April.
Uses
Red hot poker is ideal for solitary planting in lawns and tall perennial borders, where it provides a strong vertical accent. It suits prairie- and gravel-style gardens, alongside coneflowers, ornamental grasses, yarrows and salvias. The stiff spikes are very long-lasting as cut flowers—they last up to two weeks in a vase. The flowers attract bumblebees and butterflies.
Gardener’s tip
Red hot poker is more often killed by winter wet than by frost. Therefore, plant it on a slight rise or somewhere water does not collect, and do not cut the leaves back in autumn—tied into a bundle, they direct rainwater away from the centre of the clump. Add a dry leaf covering only after the first frosts, not earlier.
