The kniphofia plant is also called the red-hot poker due to its tall spikes of scarlet or bright red flowers. The plant blooms in late spring and early summer. The flowers at the top of the plant are red while the ones at the bottom are green. The flowers start to turn yellow as they age. The kniphofia plant can be grown in bright sun or light shade. The soil used for planting should be rich in iron and fast draining. The plants thrive in areas with dry air rather than humid air.
The kniphofia plant is a native of South Africa and grows best in direct sunlight though it tolerates light shade as well. The plant is a fast grower and needs about 1 square yard of growing space per plant. It requires ample moisture in its active growing period. Water quantity needs to be reduced after the flowers bloom and during wintertime. It is very important to keep the soil dry, especially during winter as the plants are very susceptible to root rot. Fungicides are often used to save plants from root rot. Dry air is most suitable for the plant and it is best grown in garden soil which is very well-drained. In regions with high humidity and heavier soils, it is recommended to plant kniphofia in raised beds. The soil quality can range from neutral to alkaline. The plant also tolerates acidity pretty well.
Care During Winter
The plants need to be heavily mulched in areas with severe winter. If weather is particularly harsh it is recommended to remove the rope-like plant roots during fall and store in a cool, dry place for the winter because the kniphofia plant is very tender. During spring, the plant can be replanted by dividing the thick root stalk. The plants grow equally well from seeds, which are likely to produce flowers in mixed colors.
