Kniphofia uvaria 'GRANDIFLORA' torch lily, red hot poker

Grandiflora is a rather robust torch lily variety, similar to Flamenco. It bears dense, fat, narrowly ovate, spike-like inflorescence composed of small, glossy, tubular flowers. They are yellow at the bottom, orange in the middle, and most of the spike till the top is covered with rich saffron red flowers. They open from late June and strong and old plants can continue flowering until late August.

Stems are fleshy but strong, almost one meter tall, and hold flowers firmly without breaking in strong winds. Strap-like or sword-like leaves are narrow, upright, mid green.

Torch lily is perfect for modern and exotic landscapes and will also fit in mixed perennial borders where its vertical accent will beautifully contrast with other arching or mound-forming plants. It is not ideal for growing in pots – first due to the roots, and secondly it is not very aesthetical.

Grow it in full sun only, in humus-rich, moist but free-draining soil. Fertilizing is beneficial from early summer but is not necessary. It is hardy to about -27 °C if mulched, protecting the clump with a layer of fir branches is recommended for zone 6 winters. Tie up the clump before winter to prevent the crown from excess moisture. Protect newly emerging stems with flower buds against slugs.
