In the garden
Kniphofia 'Green Jade' produces a compact, multi-stemmed clump of deciduous foliage and carries its bloom in the summer months from June to September. The cultivar performs best where it receives uninterrupted sun and where flowers can be seen from paths or seating areas. Plant into a south- or west-facing position in loam or a free-draining sandy mix; the soil should hold some moisture but never become waterlogged. It tolerates acid to neutral soils and will cope in both exposed and more sheltered sites, so it is suitable for frontline beds and seaside locations. The H5 hardiness categorisation means it is hardy across most of the UK. Use Kniphofia 'Green Jade' towards the front or centre of summer borders, in gravel beds or in coastal schemes where exposure and free drainage are typical. Its upright summer flowering makes it suitable where a concentrated seasonal display is wanted; position it so the bloom period, June to September, can be enjoyed from nearby paths or patios.
