ToxicityTo humans
Red hot poker is not widely regarded as a toxic plant to humans. Most sources suggest that it is safe when touched or if small quantities are accidentally ingested. However, as with any plant material, individual allergies and sensitivities can occur. If ingested in large amounts, there is potential for stomach upset or discomfort. It is always advisable to avoid eating garden plants unless they are known to be edible and to teach children not to eat plants due to potential risks that may be associated with other species.
To pets
Red hot poker is also not widely recognized as a toxic plant to pets. It is generally considered non-toxic to dogs, cats, and other domestic animals. However, animals may have individual sensitivities, and the consumption of any plant material can potentially cause mild stomach upset or gastrointestinal irritation. If you notice your pet has eaten a significant amount of red hot poker and is showing signs of distress, it is best to consult with a veterinarian.

WaterFor Red Hot Poker plants, maintain consistent moisture, especially during hot and dry periods. Water the plant deeply once a week, providing about an inch of water each time. In gallons, this translates to approximately 0.5 gallons for a 1-square-foot area, depending on soil type and climate. During the cooler seasons or in naturally moist conditions, reduce watering frequency. Ensure adequate drainage to prevent root rot and avoid overhead watering to keep the foliage dry.
LightRed Hot Pokers thrive in full sunlight, requiring at least six hours of direct sunlight daily. A south-facing location is often ideal to ensure the plant receives ample light to support vigorous growth and optimal blooming. Avoid placing them in heavily shaded areas, where they may struggle to flourish.
TemperatureThe Red Hot Poker is tolerant of a wide range of temperatures but grows best in conditions between 50°F and 85°F. They can survive temperatures as low as 10°F, making them suitable for colder climates, but they prefer the warmer end of their temperature range. Protect the plants from extreme cold by adding mulch in the winter if temperatures are expected to drop below their minimum threshold.
PruningPrune Red Hot Pokers in early spring or late fall, removing dead or spent flower spikes to encourage new growth and improve the plant's appearance. Deadheading, or cutting off the old blooms, can sometimes prompt a second round of flowering. Prune back the foliage to a few inches above the ground in late fall to prepare the plant for winter.
CleaningAs needed
SoilThe Red Hot Poker (Kniphofia 'Lord Roberts') thrives in well-draining soil with a blend of loam, organic matter, and sand to facilitate drainage. It prefers a soil pH range of 6.0 to 6.5. To create an optimal soil mix, combine two parts loam, one part peat or compost, and one part gritty material like perlite or coarse sand.
RepottingThe Red Hot Poker does not require frequent repotting and can often be left undisturbed for several years. When growth indicates it is root-bound, typically every 3-5 years, repot in the spring or divide clumps to rejuvenate and propagate.
Humidity & MistingRed Hot Poker is relatively adaptable but prefers moderate humidity levels. It does not require high humidity environments and can tolerate some dryness. Strive to maintain average room humidity without special adjustments for this plant.

Life cycleThe Red Hot Poker 'Lord Roberts' begins its life cycle with seed germination, which occurs when conditions of moisture, temperature, and light are favorable, typically in spring. Following germination, seedlings develop into juvenile plants, establishing a root system and producing foliage. As the plant matures, it forms a clump of strap-like leaves from which tall flower spikes emerge during its blooming period in the summer. After pollination, often by hummingbirds and bees attracted to its tubular flowers, the plant sets seed, which can be dispersed by wind or collected for propagation. The foliage remains evergreen in milder climates but may die back in colder regions, with the plant entering a period of dormancy over winter. The following spring, the cycle begins anew with fresh growth and another round of flowering.

Spring to Summer
The most popular method of propagating the Red Hot Poker 'Lord Roberts' is by division. This process is best done in late spring as the plants emerge from dormancy or early fall when the flowering has ceased and the plant is not in active growth. To propagate by division, carefully dig up an established clump and gently separate it into smaller clumps, ensuring that each new section has a share of roots and several growth points or shoots. These divisions should then be replanted at the same depth they were growing previously, spaced about 18 to 24 inches (45 to 60 centimeters) apart to allow for mature spread. Water the newly planted divisions thoroughly to help establish them. This method of division helps to rejuvenate older clumps that may have become woody and less floriferous over time, while also providing new plants to expand the garden or share with fellow gardeners.
