USPP27653P3 - Lavandula plant named ‘DOWPHSCNT’ - Google Patents

Abstract

A new and distinct Lavender cultivar named ‘DOWPHSCNT’ is disclosed, characterized by short, compact plants. Plants produce unique short, wide flower spikes, uniform inflorescence and very compact plant form. The new variety is a Lavandula, normally produced as an outdoor garden or container plant.

Description

Latin name of the genus and species: Lavandula intermedia.

Variety denomination: ‘DOWPHSCNT’.

BACKGROUND OF THE INVENTION

The new Lavandula cultivar is a product of a planned breeding program conducted by the inventors, Simon Charlesworth and Fiona Wilson, in Kent, the United Kingdom. The objective of the breeding program was to produce new Lavender varieties for ornamental commercial applications.

The parent variety is the, unpatented commercial variety Lavandula ‘Abrialii’. Plants of the parent variety were treated to induce mutation. Cuttings from the treated plants were selected, propagated and plants observed for noticeable differences from the parent variety.

Asexual reproduction of the new cultivar was performed by vegetative cuttings. This was first performed in Kent, the United Kingdom during 2009. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type in multiple successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘DOWPHSCNT’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘DOWPHSCNT’ These characteristics in combination distinguish ‘DOWPHSCNT’ as a new and distinct Lavender cultivar:

• • 1. Compact plant.
  • 2. Short plants with a moderate growth rate.
  • 3. Broad foliage.
  • 4. Short flower spikes.
  • 5. Wide floral calyces.

Plants of the new cultivar ‘DOWPHSCNT’ are similar to plants of the parent variety in most horticultural characteristics, however, plants of the new cultivar ‘DOWPHSCNT’ differ in the following;

• • 1. Shorter plant height.
  • 2. Broader foliage.
  • 3. Shorter flower heads with wider calyces.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘DOWPHSCNT’ are comparable to the unpatented commercial variety Lavandula intermedia ‘Provence’. The two Lavender varieties are similar in most horticultural characteristics; however, the new variety ‘DOWPHSCNT’ differs in the following:

• • 1. Plants of the new variety are at least 20% smaller in height and width.
  • 2. Flower spikes of the new variety are shorter, approximately 8 cm compared to 18 cm.
  • 3. Flower spikes of the new variety are wider, approximately 2 cm compared to 1 cm.

Plants of the new cultivar ‘DOWPHSCNT’ can also be comparable to the unpatented commercial variety Lavandula ‘Grosso’. The two Lavender varieties are similar in most horticultural characteristics; however, the new variety ‘DOWPHSCNT’ differs in the following:

• • 1. Plants of the new variety are approximately shorter, approximately 60 cm at maturity compared to 90 cm mature height of this comparator.
  • 2. Flower spikes of the new variety are shorter, approximately 8 cm compared to 18 cm.
  • 3. Flower spikes of the new variety are wider, approximately 2 cm compared to 1.5 cm.
  • 4. Flower color of the new variety is lighter than flower color of this comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘DOWPHSCNT’ grown outdoors, in the ground in Kent, England. Age of the plant photographed is approximately 4 years from a rooted cutting.

FIG. 2 illustrates a close up of the flowers.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
