Kniphofia 'Nobilis'

Kniphofias to grow

From a pale-lemon cultivar given to Beth Chatto by Cedric Morris to the soft tawny ‘Toffee Nosed’, new breeding has taken kniphofia far beyond orange

On a trip to South Africa I was awestruck by the sight of hundreds of incandescent flower spikes glowing in the evening light. They were the flowers of kniphofia, the aptly named red hot poker, and on that visit, I saw many more species, some with pale-lemon flowers, some soft pink but most with the vibrant orange with which the plant is most associated. Seeing them in their native habitat opened my eyes to the splendour of the genus and how wonderful they might look in a garden setting if grown among grasses and other southern hemisphere plants rather than the tatty clumps I remember from the suburban gardens of my childhood.


A genus of about 70 species of mainly evergreen perennial plants with hundreds of cultivars and hybrids, kniphofias are grown for their spikes of brightly coloured flowers and all species are found in areas of high rainfall in eastern and southern Africa, with the vast majority occurring in South Africa.

Season Flowering from April to October; most forms flower in midsummer.

Conditions Moist soil that drains well in the winter and an open, sunny situation are ideal. Established plants can tolerate periods of drought.

Hardiness Except in very wet areas most are hardy throughout Britain. A few need protection from winter cold and wet. RHS H4-6. USDA5a-9b.
