Kniphofias in general are recognized as architectural marvels, easy to cultivate, and drought-tolerant plants. Their beauty is not only evident in their showy flowers, but also in their remarkable evergreen, Aloe-like leaves, which provide something to look at during the non-flowering months.

Kniphofias are rhizomatous plants that can be reproduced through division, generating clumps that can then be divided to enlarge the population. Propagation from seed has also proven successful; however, it has been discovered that the low number of sexually reproducing plants may have an effect on the number of seedlings produced from seeds, which can have a negative impact on the plant’s long-term survival.

In an article published in Veld and Flora in 1985, J.P. Roux describes how readily Kniphofia northiae was cultivated from seed in the Drakensberg National Botanic Garden: “The seed was planted in August in a tray with a 3:1:1 ratio of loam, sand and compost and was covered in clean river sand. Germination took place 30 days later. The seedlings developed fast and were first established in 60 mm pots after which they were repotted into 120 mm pots. The first plants were established in the garden as year-old seedlings. Once established the plants developed at considerable rate.” They were planted on a well-drained, north-east facing slope to prevent crown rot, and the first inflorescence appeared two years after germination. Thus, depending on how quickly one wants to show off these wonderful kniphofias, both procedures are simple, but the division approach is advised for the simplest and quickest results.

Kniphofia northiae grows best in moist but well-drained soil; both loam and sand soil are recommended mediums since they allow excess water to drain away, as poor drainage can be detrimental. The soils must be acidic and neutral in pH, and they must receive full or partial shade. Soggy circumstances or standing water is not ideal for any kniphofia species, but thorough watering is essential during the growing season to ensure their survival and flowering success. This species is evergreen and won’t die back during winter, it is easy to cultivate and is very frost hardy, surviving temperatures as low as -10°C.

In the spring, plant rhizomes (when employing the vegetative propagation method) or sow seeds. This plant is frost and drought-tolerant. After 4 to 5 years, divide the clumps; in colder areas, divide the plants in the spring; in warmer ones, divide them after they flower. The 4-5-year span is a precautionary measure to avoid disrupting the floral cycle.

Kniphofias are well-known for their ability to attract birds, bees, and butterflies, and K. northiae in particular is well-suited to architectural, coastal, and gravel and rock garden themes.

Some valuable kniphofia growth tips and tactics from the Easy-to-grow-bulbs website:
Improve drainage and promote a healthy start by amending the soil with finely ground bark, decomposed manure, or compost.
Plant Kniphofia in the ground rather than containers since mature plants develop into enormous clusters that can be 0.5-1 m across.
When dividing a clump make sure that the rhizomes you cut off have roots attached, making it easier to tell which end should face upwards.
Enjoy the stunning flowers, snipping a couple for dramatic arrangements, as doing so will not harm your plants and will actually stimulate more blossoms to grow.
