plant named ‘KNI610’

Abstract

A new and distinct cultivar of Kniphofia plant named ‘KNI610’, characterized by its upright and compact plant habit; moderately vigorous growth habit; freely flowering habit; repeat flowering over a long period of time; and pale yellow-colored flowers with orange-colored apices.

Description

Botanical designation: Kniphofia uvaria.

Cultivar denomination: ‘KNI610’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Kniphofia plant, botanically known as Kniphofia uvaria and hereinafter referred to by the name ‘KNI610’.

The new Kniphofia originated from a cross-pollination conducted by the Inventor in 1996 of two unnamed proprietary selections of Kniphofia uvaria, not patented. The new Kniphofia was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled greenhouse environment in Cobbitty, New South Wales, Australia in November, 2006.

Asexual reproduction of the new Kniphofia plant by vegetative divisions in a controlled environment in Macquarie Fields, New South Wales, Australia since December, 2006 has shown that the unique features of this new Kniphofia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Kniphofia have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘KNI610’. These characteristics in combination distinguish ‘KNI610’ as a new and distinct Kniphofia plant:

• • 1. Upright and compact plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Freely flowering habit.
  • 4. Repeat flowering over a long period of time.
  • 5. Pale yellow-colored flowers with orange-colored apices.

Plants of the new Kniphofia can be compared to plants of the female parent selection. Plants of the new Kniphofia differ from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Kniphofia are shorter than plants of the female parent selection.
  • 2. Plants of the new Kniphofia and the female parent selection differ in flower color as plants of the female parent selection have lemon yellow-colored flowers.

Plants of the new Kniphofia can be compared to plants of the male parent selection. Plants of the new Kniphofia differ from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Kniphofia and the male parent selection differ in leaf color.
  • 2. Plants of the new Kniphofia repeat flower whereas plants of the male parent selection do not repeat flower.
  • 3. Plants of the new Kniphofia and the male parent selection differ in flower color as plants of the male parent selection have orange-colored flowers.

Plants of the new Kniphofia can also be compared to plants of Kniphofia uvaria ‘Little Maid’, not patented. In side-by-side comparisons conducted in Macquarie Fields, New South Wales, Australia, plants of the new Kniphofia differed from plants of ‘Little Maid’ in the following characteristics:

• • 1. Plants of the new Kniphofia flowered earlier than plants of ‘Little Maid’.
  • 2. Plants of the new Kniphofia and ‘Little Maid’ differed in flower color as plants of ‘Little Maid’ had lemon yellow-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Kniphofia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Kniphofia plant.

The photograph at the bottom of the sheet comprises a side perspective view of a typical plant of ‘KNI610’ grown in a container.

The photograph at the top of the sheet is a close-up view of a typical inflorescence of ‘KNI610’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in containers during the winter in a polyethylene-covered greenhouse in Bonsall, Calif. and under cultural practices which approximate commercial production. During the production of the plants, day temperatures ranged from 21° C. to 27° C., night temperatures ranged from 16° C. to 20° C. and light levels ranged from 4,200 to 5,000 foot-candles. Plants were six months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
