Kniphofia, also sometimes called Tritoma, Red hot poker, Torch lily or Red Hot Poker plant, is a genus of plants in the family Xanthorrhoeaceae, that includes 70 or more species native to Africa. Some species have been commercially used horticulturally and are commonly known for their bright, rocket-shaped flowers. These plants produce spikes of upright, brightly-colored, red-to-orange flowers. This gives names such as "torch" and "red hot poker" to many of them. The flowers produce copious nectar while blooming and may attract many insects species. The Kniphofia genus is named after Johann Hieronymus Kniphof, an 18th century German physician and botanist. Kniphofia caulescens is a species 'Red Hot Poker' and originates in mountainous regions of Lesotho and South Africa and is possibly the hardiest of all pokers. It has fabulous broad blue-grey evergreen leaves (unusual for pokers) and, late in the summer, it throws up stems of large soft-orange and yellow flower spikes. Superb in a sunny well-drained position - combines well with grasses. Eventually forms a good sized clump. This is an evergreen perennial to 1.2m.
Kniphofia caulescens are not difficult once you know that at home in South Africa they get plenty of rain as they are growing. Not too dry in summer and as dry as you can arrange in winter - good drainage is fairly essential. It grows in soils ranging from a pH of 6 (acidic ranges from 5.6 to 6) to 7.8 (slightly alkaline ranges from 7.6 to 8). It is adapted to loam, sand, clay loam, loamy sand, sandy clay loam and sandy loam soils, and prefers high fertility.
Uses: Kniphofia caulescens can be used in herbaceous borders devoted to hot colours. Here they can look particularly effective when used with other vibrant plants such as the Salvias, Crocosmia and late flowering Helianthus and ornamental grasses etc.
