USPP27446P2 - Kniphofia plant named ‘TNKNIPR’ - Google Patents

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, large inflorescences of red flowers on short stems, a very long bloom time with repeat blooming from July through October in Canby, Oreg., a short habit, narrow, grassy leaves, and excellent vigor.

Description

Botanical denomination: Kniphofia spp.

Cultivar designation: ‘TNKNIPR’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Kniphofia, and given the cultivar name is ‘TNKNIPR’. Kniphofia is in the family Xanthorrhoeaceae. ‘TNKNIPR’ 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 K85-6, as the seed parent and Kniphofia K90-1, 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 K85-6, the seed parent, the new cultivar is more free flowering and has a shorter habit.

Compared to Kniphofia K90-1, the pollen parent, the new cultivar is more free flowering and has a red flowers rather than cream and red.

Compared to Kniphofia ‘Red Hot Popsicle’, U.S. Plant Pat. No. 24,036, the new cultivar is ⅓ shorter.

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. large inflorescences of red 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, 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.
