USPP18155P2 - Lavender plant named ‘D01-24’ - Google Patents

Abstract

A new and distinct cultivar of Lavender plant named ‘D01-24’, characterized by its compact, upright, outwardly spreading and mounded plant habit; freely branching, dense and bushy plant form; and light pink-colored flowers with showy light pink-colored terminal flower bracts.

Description

Botanical designation: Lavandula stoechas.

Cultivar denomination: ‘D01-24’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lavender, botanically known as Lavandula stoechas and hereinafter referred to by the name ‘D10-24’.

The new Lavender is a product of a planned breeding program conducted by the Inventor in Kulnura, New South Wales, Australia. The objective of the breeding program is to create new compact and freely branching Lavender cultivars with large and attractive flowers and good garden performance.

The new Lavender originated from a cross-pollination made by the Inventor in 2000 of the Lavandula stoechas cultivar Madrid Pink Improved, disclosed in U.S. Plant Pat. No. 14,205, as the female, or seed, parent with an unknown selection of Lavandula stoechas, not patented, as the male, or pollen, parent. The new Lavender was discovered and selected by the Inventor as a single flowering plant with the progeny of the stated cross-pollination grown in a controlled environment in Kulnura, New South Wales, Australia in 1999.

Asexual reproduction of the new cultivar by terminal cuttings at Kulnura, New South Wales, Australia, since 2001, has shown that the unique features of this new Lavender are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar D01-24 have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment 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 ‘D01-24’. These characteristics in combination distinguish ‘D01-24’ as a new and distinct cultivar:

• • 1. Compact, upright, outwardly spreading and mounded plant habit.
  • 2. Freely branching, dense and bushy plant form.
  • 3. Light pink-colored flowers with showy light pink-colored terminal flower bracts.

Plants of the new Lavender differ from plants of the female parent, the cultivar Madrid Pink Improved, in the following characteristics:

• • 1. Plants of the new Lavender are more compact than plants of the cultivar Madrid Pink Improved.
  • 2. Plants of the new Lavender and the cultivar Madrid Pink Improved differ in petal coloration.

Plants of the new Lavender can be compared to plants of the cultivar Kew Red, not patented. In side-by-side comparisons conducted by the Inventor in Kulnura, New South Wales, Australia, plants of the new Lavender diffused from plants of the cultivar Kew Red in the following characteristics:

• • 1. Plants of the new Lavender were larger than plants of the cultivar Kew Red.
  • 2. Plants of the new Lavender were denser and bushier than plants of the cultivar Kew Red.
  • 3. Plants of the new Lavender and the cultivar Kew Red differed in petal and terminal flower bract coloration as plants of the cultivar Kew Red had dark pink-colored petals and pink-colored terminal flower bracts.

The photograph at the top of the sheet comprises a close-up view of typical inflorescences of ‘D01-24’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. Plants used for the aforementioned photographs and following description were grown under conditions which closely approximate commercial production conditions during the winter and early spring in a polycarbonate-covered greenhouse in Lompoc, Calif. for about 28 weeks in containers. During the production of the plants, day temperatures ranged from 18° to 24° C., night temperatures ranged from 4° to 10° C., and light levels ranged from 4,000 to 8,000 foot-candles.
