Maintenance- Design- Planting Tips

The glowing torch-like flowers of Kniphofia are reliable midsummer bloomers. From a design perspective the flower spikes of these plants provide great vertical accents. Many sizes and colors of Kniphofias have been developed, including reds, oranges, yellows, and near whites. The the flower colors can be dramatic and intense, so take care in selecting flower colors that blend well with your plants.

The Palo Alto Demonstration Garden has several Kniphofias including "Christmas Cheer', which is a UC Davis "All-Star". It has brilliant orange buds that open to a deep-gold tubular flower. Kniphofia 'Christmas Cheer' blooms in the fall and winter unlike many other Kniphofias.

We deadhead these plants because the old flower spikes are not that attractive. When the leaves start looking shabby in the winter, we cut back the foliage about three inches above the ground. Kniphofia will then come back beautifully in the spring. The plant divides easily when you want to spread it around, but it doesn't seem to need dividing to stay vigorous.
