Derivation of name and historical aspects
Kniphofia rooperi belongs to the Asphodelaceae family which was formerly part of the Liliaceae family. It consists of mostly herbs but includes woody forms such as the tree aloe ( Aloe barberae). It is found in Europe, Asia and Africa where it is mostly centred in South Africa with Kniphofia and Aloe being the most prominent members. There are 17 genera in existence and approximately 750 species with 10 genera occurring in South Africa.

The genus Kniphofia is named after J.H. Kniphof, a professor of medicine at Erfurt University, born 1704, who died in 1763. The species name rooperi is named after Captain Edward Rooper who was stationed in East London in South Africa between 1848 and 1850. He was a painter of flowers and landscapes and was the one who sent this plant to England.

The nectar-rich flowers attract insects such as bees and butterflies .

Uses and cultural aspects
Traditionally the rootstock of Kniphofia rooperi was used as a good luck charm by African children. It is also used in traditional healing to treat chest complaints. It is also a good garden plant.

Growing Kniphofia rooperi

This evergreen, fast-growing perennial does best in sandy soil which is moist, but drains well. Enriching the soil with humus improves growth. It prefers full sun although it can tolerate semi-shade, but it may not flower as prolifically.

Plants can be propagated from seed, cuttings or by means of dividing. Seed should be germinated in a cold frame in spring. Established plants can be divided in late spring. One can also try cutting offsets away from the main clump with a sharp spade, especially in the case where the parent plant is old and woody. Leave them to grow on for a season or two before re-planting.

To ensure optimal and healthy growth it is important to clean the plant of dead and decaying leaves, as well as removing spent flower spikes. Ensure that they are taken out at the base. These flower spikes can cause nasty cuts when gardeners work with the plants and in addition could become a hiding place for pests such as earwigs and woodlice.

Where pests are concerned, these plants can be damaged by snails and slugs, as well as thrips which could cause mottling of the leaves.

Diseases that could prove to be a problem is violet rot if the drainage of the soil is impaired.
