Abstract

A new and distinct cultivar of Lavandula plant named ‘Early Summer’, characterized by its compact, upright and somewhat outwardly spreading plant habit; freely branching growth habit; dense and bushy plant form; early and freely flowering habit; dark violet blue-colored flowers with violet-colored terminal flower bracts; flowers arranged in compact verticillasters on crowded spikes; and good garden performance.

Description

Botanical designation: Lavandula stoechas.
Cultivar denomination: ‘EARLY SUMMER’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Lavandula plant, botanically known as Lavandula stoechas and hereinafter referred to by the name ‘Early Summer’.
The new Lavandula plant is a whole plant mutation of Lavandula stoechas ‘Alexandra’, not patented. The new Lavandula plant was discovered and selected by the Inventor in 2006 as a single flowering plant within a population of plants of ‘Alexandra’ in a controlled outdoor nursery environment in Komen, Belgium. The new Lavandula was selected on the basis of its compact plant habit and early flowering habit.
Asexual reproduction of the new Lavandula by terminal cuttings in a controlled greenhouse environment in Komen, Belgium since 2006 has shown that the unique features of this new Lavandula plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Lavandula 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 ‘Early Summer’. These characteristics in combination distinguish ‘Early Summer’ as a new and distinct cultivar of Lavandula plant:
    • 1. Compact, upright and somewhat outwardly spreading plant habit.
    • 2. Freely branching growth habit; dense and bushy plant form.
    • 3. Early and freely flowering habit.
    • 4. Dark violet blue-colored flowers with violet-colored terminal flower bracts; flowers arranged in compact verticillasters on crowded spikes.
    • 5. Good garden performance.
Plants of the new Lavandula differ from plants of the parent, ‘Alexandra’, in the following characteristics:
    • 1. Plants of the new Lavandula are more compact than plants of ‘Alexandra’.
    • 2. Plants of the new Lavandula flower earlier than plants of ‘Alexandra’.
Plants of the new Lavandula can be compared to plants of Lavandula stoechas ‘Anouk’, disclosed in U.S. Plant Pat. No. 16,685. Plants of the new Lavandula differ from plants of ‘Anouk’ in the following characteristics:
    • 1. Plants of the new Lavandula are more compact than plants of ‘Anouk’.
    • 2. Plants of the new Lavandula flower earlier than plants of ‘Anouk’.
    • 3. Plants of the new Lavandula and ‘Anouk’ differ in leaf, flower and terminal flower bract color.
    • 4. Plants of the new Lavandula have longer terminal flower bracts than plants of ‘Anouk’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Lavandula 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 Lavandula plant.
The photograph at the top of the first sheet comprises a side perspective view of a typical flowering plant of ‘Early Summer’ grown in a container.
The photograph at the bottom of the first sheet is a close-up view of a typical flowering stem of ‘Early Summer’.
The photograph at the top of the second sheet is a close-up view of a typical inflorescence of ‘Early Summer’.
The photograph at the bottom of the second sheet is a close-up view of the upper surface of a typical leaf of ‘Early Summer’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs, following observations and measurements describe plants grown during the spring in 11-cm containers in an outdoor nursery in Odense, Denmark and under conditions and practices which approximate those generally used in commercial Lavandula production. Plants were 27 weeks old when the photographs and description were taken. During the production of the plants, day temperatures ranged from 15° C. to 27° C. and night temperatures ranged from 3° C. to 15° C. 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.
