Kniphofia alooides 'Amberlight' grows best in full sun, and tolerates fertile sandy or loamy soil soils and neutral to slightly acid pH. Its UK hardiness is rated H4–H6. Suggested uses include borders, rock gardens, wildlife gardens and cut flowers. It is native to South Africa.
About
Kniphofia alooides 'Amberlight' is a clump-forming, upright perennial in the Asphodelaceae grown for its tall flower spikes. The foliage is narrow, arching and strap-shaped or grassy, rising as a low mound beneath the flowering stems. It flowers from June to September and suits sunny, south- or west-facing sites in fertile sandy or loamy soil that is moisture-retentive in summer yet well drained in winter.
About the genus

In the garden
Kniphofia alooides 'Amberlight' originates from South Africa and belongs to the Asphodelaceae family. As a clump-forming perennial it carries narrow, arching leaves from which upright spikes emerge; the flowering season runs from June to September, making it a summer-forward presence in the border. Plant in full sun on fertile sandy or loamy soil with a neutral to slightly acid pH; choose a south- or west-facing aspect when possible. Provide a soil that holds moisture during the growing season but drains freely through winter, and avoid siting where crowns will remain waterlogged. The hardiness rating H4–H6 means it ranges from average to very hardy across UK garden conditions, so it will establish reliably in much of the country if winter drainage is adequate. Use Kniphofia alooides 'Amberlight' at the back of herbaceous borders, in sunny gravel or rock gardens, and in wildlife-friendly plantings where tall cut stems are wanted. It also works well for summer cutting. The June–September spikes stand clear above the grassy leaves, delivering a long season of interest and suitable stems for cutting into arrangements.

Care notes
Pruning and caring for Kniphofia alooides 'Amberlight'
- Cultivation
- What most red hot pokers want is summer moisture combined with winter dryness. Plant on a free-draining site, water generously while the spikes are forming, then protect the crowns of less hardy kinds with a dry mulch or by tying the leaves up over the centre in autumn.
- Pruning
- Remove faded spikes at the base. Cut deciduous foliage down in late autumn; on evergreens pull away dead leaves by hand rather than shearing the whole clump.
- Propagation
- Divide established clumps in late spring — autumn division risks rotting. Species germinate readily from seed but take two to three years to flower.
- Pest resistance
- Usually undemanding, but aphids, thrips, slugs and snails can all take advantage of the crown and new growth.
- Disease resistance
- Healthy in suitable conditions. Crown and root rot follow winter waterlogging.
