Planting kniphofia

The kniphofia, ember of satan, tritome or even false aloe, is a perennial with rhizomes native to South Africa from the Liliaceae family . It takes its name from the surname of a German botanist from the beginning of the 18th century, JH Kniphof Its evergreen foliage is reminiscent of lily or daylily . Its very original , exotic-looking flowering makes it an ideal flower for creating bouquets and colorful beds. The ember of satan flowers from June to October , even later in the milder regions. Easy to cultivate, the kniphofia has a rapid growth and its size varies from 50 cm to 1m50 high depending on the variety.

The kniphofia appreciates:

  • A sunny position to promote flowering
  • Calcareous and well-drained soil
  • A soil/soil mixture
  • Be sheltered from the wind

Plant the kniphofia in the spring  , respecting:

  • A depth of 10 to 15 cm
  • spacing of 40 cm between each plant


If the kniphofia does not flower, it is probably because it lacks sun . It is then possible to move it in the spring before flowering. By the way, in the period of spring recovery, the tritoma can be divided.

As the kniphofia has a long flowering (3 weeks to 1 month and a half), there is enough to enjoy it for a long time in the beds. Small peculiarity: the flowers of the kniphofia change color according to the stage of maturity, thus going from bright red to lemon yellow. As the flower buds open from the bottom upwards, the flowers located on the bottom of the stem fade more quickly.

Size and Care

Cut back the foliage by half the length in early spring to promote regrowth. Also remember to remove faded flowers as you go along in order to stimulate new flowering. When fall arrives, mulch the foot of the false aloe to protect it from the cold, especially if you live in an area with freezing temperatures. In the mildest regions, you may be lucky enough to see it bloom until December.

The kniphofia forms a compact and elegant clump. In a composition in the garden, the ember of satan is associated with agave or grasses . Combined with the agapanthus (also from the Liliaceae family ), it forms a sumptuous colorful mass. This melliferous plant also has the advantage of providing cover for bees and pollinating insects .
