Red hot pokers (Kniphofia) are herbaceous perennials prized for their tall, showstopping flower spikes in bright red, orange, yellow, and other colors. They are also commonly known as torch lilies, though they are not true lilies (i.e., they are not members of the Liliaceae family). There are over 60 species in the Kniphofia genus, and most of the varieties available today are hybrids. Among the most popular are the dwarf cultivars that have clumping foliage reaching 1 to 2 feet high and flower stalks that stand over 2 feet tall. By comparison, one common species plant, Kniphofia uvaria, reaches 3 to 4 feet in height.Perhaps the best feature of these plants is their long blooming period. Many varieties will brighten a garden with bright flowers for much of the summer. They are best planted in spring and will reach full height within each growing season.

How to Care for the Plant
Water
Kniphofia are water-wise plants and have modest water needs once established. Water frequently after planting and less frequently in subsequent seasons.
Fertilizer
Plants in nutritious soil typically do not need feeding. If the soil is poor, feed the plants with a slow-release fertilizer to promote blooms.
Sunlight
Grow your red hot poker plants in full sun for the best blooms. They will tolerate some shade and can benefit from afternoon shade in climates with hot summers.
Soil
These plants need soil that drains well. They are generally tough perennials, but poor drainage is one of the few things that will kill them. Damp soil is particularly problematic in winter, as it promotes root rot.
Temperature
Indigenous to South Africa, red hot pokers are listed for growing in planting zones 6 through 9, but they can be hardy as far north as zone 5, especially with good drainage and mulch. In cold climates, winterize the plants by covering their crowns with mulch.
