Kniphofia Elvira (Red Hot Poker)

Kniphofia ‘Elvira’ produces incredibly impressive, long, and densely packed spikes of fiery orange flowers from late spring to early fall. The flower spikes bloom in succession over a long bloom period. Native to South Africa, this showy plant is ‘self-cleaning’, with spent flowers quickly dropping off so that the vibrant coloring never becomes tainted.

  • Changing color as the flower matures, this robust perennial displays the deepest shades in bud and fades as the flower opens, resulting in a bicolor look, adding interesting splashes of color to any sunny garden. The stout flowering scapes rise proudly above tufted clumps of medium green leaves.
  • Growing up to 40 in. high (100 cm) with a spread of 2 ft. (60 cm), this Red Hot Poker enjoys a sturdy stem. However, some protection from strong winds would be recommended. 
  • This rhizomatous perennial performs best in full sun, in a sandy soil that has been enriched with humus. However, any deep, moist but well-drained soil will do. It can tolerate partial shade, but flowering will be reduced. Good drainage is essential to prevent crown rot
  • Droughtdeer and rabbit tolerant, Kniphofias attract butterflies and are a favorite of hummingbirds.
  • Virtually disease free
  • Kniphofias provide interesting vertical accents in the garden, among other summer-blooming perennials. They look at their best with Achillea (yarrows), Helenium Autumnale (sneezeweed), Hemerocallis (daylilies), and Rudbeckia (coneflowers).
  • While primarily used in perennial borders, Red Hot Pokers are also well suited to naturalistic settings, water edges, or exotic style combinations. Plant them in front of an evergreen background, or as a stand-alone specimen – and be sure they will draw the attention of all onlookers. Never plant your Red Hot Pokers with their crown deeper than 3 in. (7 cm).
  • Remove spent flower spikes to encourage more bloom and protect their crowns in winter in hardiness 6.
  • The foliage tends to suffer in the winter months. You may want to tie foliage together in the fall to prevent water from entering the crown of the plant. Alternatively, you may cut the foliage off at the base in late fall.
  • Should be planted in the spring or in the fall.
  • Can be propagated by division or be grown from seed. Division should be done in the spring or late fall
