Plant Taxonomy of Red Hot Poker Plants:
Plant taxonomy places red hot poker plants in the genus, Kniphofia (I use this common name to refer them generically, even though, technically, it is applied specifically to Kniphofia uvaria). They go by other common plant names as well, including "tritoma" and "torch lily"; I use these names interchangeably.
While I relate some information below that applies in a general sense to the genus, my focus is on two dwarf types that I grow. Their cultivar names are 'Pineapple Popsicle' and 'Mango Popsicle.'
Characteristics of Dwarf Torch Lilies:
Terra Nova Nurseries has put out what they call a "Popsicle Series" of compact or "dwarf" red hot poker plants. As mentioned above, I grow two of them: 'Pineapple Popsicle' and 'Mango Popsicle.' The former produces yellow flowers on its flower stalks, while the latter bears mango orange flowers. The Popsicle Series also offers dwarf torch lilies that are red and two-toned.
Except for floral color, these two dwarf torch lilies are very similar perennials. The grassy, clumping foliage reaches a height of about 1-2 feet, but when you add the flower stalk into the equation, these torch lilies will reach over 2 feet tall. 'Pineapple Popsicle' grows to the greater width of the two: about 2 feet. The blooms lowest down on the flower stalk dry up and fade first, turning a pale brown. This fading then progresses up the rest of the stalk, until, finally, reaching the top, which is last to lose its color.

Care for Red Hot Poker Plants:
Mulch for winter protection at the Northern end of the suggested growing range. Likewise, wait till spring to prune back the leaves drastically; they will furnish a bit of extra protection against the cold. But it is fine to remove a few unwanted leaves here or there throughout the growing season.
Outstanding Features of Red Hot Poker Plants:
I enjoy watching the flower stalk develop. Even when it first attains some significant height, the flowers are not yet open. Instead, they pop up as a network of tightly-packed beads at the tip of the flower stalk, which, at this stage, reminds me ever so much of a rattlesnake's tail.
But what makes torch lilies so popular is their vibrant color, the spiky appearance of their flower stalks and the fact that they are long-blooming perennials.
Because they're drought-tolerant, they could easily fit into a xeriscaping plan.
Interesting Facts: Origin of Common and Latin Names, Other Types of Kniphofia:
Bemoaning how difficult it is to remember the spelling of the genus name, Allan Armitage, in Armitage's Garden Perennials (p.179), notes that Kniphofia was named "for German botanist J. H. Kniphof." Bougainvillea plants and poinsettias are other examples of plants that are named after people and that, unhappily, practically beg us to misspell them.
Armitage also observes (p.181) that the "most common species is the old-fashioned Kniphofia uvaria," the appearance of whose inflorescence (namely, "tall spires of flowers...often scarlet or fire-engine red") was the source for the common name, "red hot pokers." But Armitage also lists various cultivars, including the white-flowered 'Ice Queen.'
