Looking for an easy-care perennial flower that is deer resistant and a favorite of hummingbirds and butterflies? Look no further than the red hot poker plant! It’s one of my personal favorites. Depending on your climate and the specific variety you choose, red hot pokers can send up their colorful flower stalks as early as June, and some can bloom through September or even October. Thankfully, red hot poker plant care is fairly easy and well worth it since these unusual plants can be absolutely jaw-dropping additions to most any garden. In this article, I’ll share all the info you need to grow these beautiful perennials.

Introduction to the red hot poker plant

Although you may have heard the red hot poker plant referred to as a “torch lily,” it isn’t officially classified along with true lilies. Rather, red hot pokers are in the aloe family (Asphodelaceae) and the genus Kniphofia—named after the German botanist Johann Kniphof. There are scores of different varieties of red hot poker plants, most of which originally hail from parts of eastern and southern Africa. In particular, many of the hybrid types now grown in the U.S. come from Kniphofia uvalra and Kniphofia triangularis—two perennials from South Africa.

A few of the many Kniphofia types to look for include ‘Flamenco’, ‘Fire Dance’, ‘Tawny King’, and a dwarf variety called ‘Red Hot Popsicle’.

Why proper red hot poker plant care matters

Red hot poker plants can be started from seed or purchased as bare root stock or live plants. You can also establish new growth from clumps of divided red hot poker transplants.

Once your red hot poker plants are properly established, they’ll provide you with striking foliage and beautiful clusters of multi-colored “torches” in shades of lemon yellow, orange, apricot, and red, depending on the variety. But it takes some attention to detail and proper red hot poker plant care before you can reap the botanical rewards. There are a couple of common mistakes that new red hot poker plant growers make that can really set back very young plants’ progress. See the next few sections for best practices around red hot poker plant care.

Where to grow red hot pokers

What is the first tenet of good red hot poker plant care? Choosing a suitable location. Most red hot poker plant varieties can overwinter if grown in USDA hardiness zones 5 through 9 and will survive a winter low temperature of -20°F.

Also, depending on your variety, red hot pokers can grow to just a couple of feet tall—or several! As such, it’s important to plan accordingly. While dwarf red hot pokers can work well along garden borders, very tall Kniphofia types should be positioned behind shorter plants.

Finally, these plants also require full sun. If you place them in a spot with too much shade, you’re less likely to have a big display of showy blooms.

Soil prep and plant spacing

Having well-draining soil is imperative for healthy red hot poker plants. Not confident about your soil’s structure and drainage? Before planting, work in organic matter like compost and aged manure to improve growing conditions.

Once you’re ready to install your new poker plants, you can usually get away with leaving just a couple of feet of space between each of them.

How often to water red hot poker plants

Established red hot poker plants are pretty drought tolerant; however, you should still water any new plants regularly. This is especially true once blooming begins. Applying an inch of water per week during warm weather should suffice, and, when in doubt, keep plants on the dry side. If you overwater your red hot poker plants, you risk losing them to root rot.

Fertilizing the plants

As long as your soil is in good shape, adding fertilizer isn’t an absolute necessity for good red hot poker plant care. If you do want to give your red hot poker flowers a boost, you can add a slow-release, organic fertilizer that’s rich in phosphorus a few weeks before you expect blooming to begin.

When to cut back red hot poker plants

Pruning is an important part of red hot poker plant care. As individual flowers come up, finish their colorful show, and then begin to die back, you should use a clean pair of scissors or garden shears to snip off each spent stalk. This keeps the plant tidy. Like peonies, red hot poker plants only produce one set of blooms per season, though cutting off spent flower stems can sometimes generate a smattering of additional flowers, depending on your variety.

When it comes to cutting back red hot poker plant leaves, It’s best to prune them down to the ground in the spring. Keeping the leaves standing over the winter can help to shield red hot poker crowns from periods of extreme cold. Trim red hot poker plants early in the spring, before new growth emerges from the center of the plant.

Winter care for red hot poker plants

Many Kniphofia species are hardy enough to be treated as perennials or, in some cases, as tender perennials in USDA Plant Hardiness Zones 5 through 9. You can add a layer of mulch to the top of your planting bed around the plant’s roots to help conserve soil moisture and provide a little extra winter protection, too. (Incidentally, when mulching near a red hot poker plant, take care not to smother the crown of the plant with mulch as this can contribute to root rot.)

Potential problems with red hot poker plants

It’s worth noting that following all of the most important red hot poker plant care tips won’t necessarily guarantee you a trouble-free garden. Case in point, although red hot poker plants are generally said to be both deer- and rabbit-resistant, there are a couple of other pests that can cause problems.

At least initially, slugs and snails may be drawn to tasty new leaves or just-emerging flower stalks. Aphids, spider mites, and thrips also sometimes help themselves to younger, more tender red hot poker plants. Fortunately, once your plants grow larger, they’re also tougher and less enticing to these critters. Still, until then, you should regularly monitor your young plants and hand-pick and remove any unwanted visitors as needed.

It is also possible for your plants to become a little too successful. In parts of California and Oregon, for example, red hot poker plants have spread to such a degree that they’ve begun to displace some native plant species.

Floral fireworks

Red hot poker plant care isn’t too challenging to master, and, if you get it right, you’ll enjoy flower spike after vibrant flower spike for weeks on end. Besides so many tubular flowers in shades of yellow, orange, and red, you should also end up with loads of hummingbirds, butterflies, and other pollinators.

Remember, in order to have success with these plants, you need to be able to provide good drainage, full sun, and regular watering sessions during warm weather and periods of flowering. These breathtaking perennial plants are sure to become a favorite in your garden as they are in mine.
