plant named ‘Poco Sunset’

Abstract

A new and distinct Kniphofia plant characterized by its habit of forming multiple crowns fast and each crown produces inflorescences in the first season, inflorescences of bicolor red orange and coral flowers on short stems, a very long bloom time with repeat blooming from July through October in Canby, Oreg., a short habit, narrow, grassy, short leaves, and excellent vigor.

Description

Botanical denomination: Kniphofia spp. (hybrid, species unknown).

Cultivar designation: ‘Poco Sunset’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Kniphofia, and given the cultivar name is ‘Poco Sunset’. Kniphofia is in the family Xanthorrhoeaceae. ‘Poco Sunset’ is a hybrid resulting from a planned breeding program to produce short, compact, reblooming Kniphofia. The cross was made using the following proprietary, unreleased plants: Kniphofia ‘K58-3’, as the seed parent and ‘K64-1’, as the pollen parent. The new cultivar, ‘Poco Sunset’ was selected for best habit, flower color, reblooming, and crown count from many seedlings of the cross in Canby, Oreg.

Compared to Kniphofia ‘K58-3’, the seed parent, the new cultivar is more free-flowering and has bicolor red orange and coral flowers rather than red. Compared to Kniphofia ‘K64-1’, the pollen parent, the new cultivar is earlier blooming and more free-flowering. Compared to Kniphofia ‘Ember Glow’, U.S. Plant Pat. No. 23,000, the new cultivar is shorter with shorter leaves in a denser habit. The flowers of the new cultivar are bicolor red orange and coral rather than orange and yellow.

Compared to Kniphofia ‘Fire Glow’, U.S. Plant Pat. No. 22,894, the new cultivar has shorter leaves and inflorescences and has flowers that are red orange and coral rather than red and yellow.

SUMMARY OF THE INVENTION

The new cultivar is unique and characterized by:

• • 1. its habit of forming multiple crowns fast and each crown produces inflorescences in the first season,
  • 2. inflorescences of bicolor red orange and coral flowers on short stems,
  • 3. a very long bloom time with repeat blooming from July through October in Canby, Oreg.,
  • 4. a short habit,
  • 5. narrow, short, grassy leaves, and
  • 6. 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.
