Description

The Red-hot poker, or Torch lily, is easily recognized by its distinctive and dramatic flower spikes during its springtime flowering cycle. When not flowering, it is recognized as a clumping perennial with soft and flexible strap-like leaves often growing 2-3 ft. high and as wide.

The Red-hot poker is a popular seasonal flowering accent plant. Many cultivars are now available from nurseries and garden centers; some are large and robust, others are petite. The common flower color is orange and yellow. One cultivar, K. u.'Christmas Cheer' is a robust cultivar with 4-5 ft. long leaves. It flowers in late fall near the holidays, with stalks reaching 4-5 ft. tall. Emerging flowers are orange-red and open to a rich gold color.

Other cultivars include: K. u. 'Malibu Yellow' has clear lemon-yellow flowers; K. u.'Shining Sceptre' has pumpkin orange flowers, and K. u. 'Wilhelm's Lance' is a giant selection with intense red-orange and yellow flowers. All are fine additions to border and mixed perennial plantings, as well as for raised planters and banks. Sunny locations, loam soil and moderate water throughout the year achieve the best performance.

Water Needs

The Red-hot poker and its many cultivars grow well in partial shade to sunny locations on loamy soils and with regular summer water. The chart shown below provides a recommended baseline guide to the monthly irrigation schedule and volume of supplemental water needed to maintain healthy growth throughout the average year. It should be noted there are several months indicated by an asterisk (*) when winter rains can provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates this plant can grow with varying amounts of water; summer water helps sustain its foliage character particularly when planted in sunny exposures.
