plant named ‘Fire Glow’

Abstract

A new and distinct Kniphofia plant characterized by its massive blooming from August through September, compact habit with multiple crowns, narrow, grassy leaves, bicolor red and yellow flowers, and excellent vigor.

Description

Botanical denomination: Kniphofia spp.

Cultivar designation: ‘Fire Glow’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Kniphofia, and given the cultivar name is ‘Fire Glow’. Kniphofia is in the family Asphodelaceae. ‘Fire Glow’ is a hybrid resulting from a planned breeding program to produce compact, reblooming Kniphofia. The cross was made using the following proprietary, unreleased plants: Kniphofia K10-1, as the seed parent, and Kniphofia K10-2, as the pollen parent. It was selected for best habit, flower color, reblooming, and crown count from many seedlings of the cross in Canby, Oreg.

Compared to Kniphofia ‘Bressingham Comet’ (an unpatented plant), the new cultivar flowers massively in late summer and fall rather than sporadically through the summer. The inflorescences of the new cultivar are bicolor orange and yellow rather than red and yellow.

Compared to Kniphofia ‘Ember Glow’, U.S. Plant patent application Ser. No. 13/066,157, the new cultivar has inflorescences that are bicolor red and yellow rather than orange and yellow.

SUMMARY OF THE INVENTION

The new cultivar is unique and characterized by:

• • 1. massive blooming from August through September in Canby, Oreg.
  • 2. compact habit with multiple crowns
  • 3. narrow, grassy leaves
  • 4. bicolor red and yellow flowers
  • 5. excellent vigor

This new cultivar has been reproduced only by asexual propagation (division, tissue culture). Each of the progeny exhibits identical characteristics to the new cultivar. Asexual propagation by leaf cuttings, tissue culture, and division using standard techniques as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.
