Abstract

A new cultivar of Lavandula plant named ‘Lavsts 11’ that is characterized by bushy, semi-open habit, and sterile bracts that change in color from lilac to red-violet, combined with blue-violet corollas. These traits sets it apart from all other existing varieties of Lavandula known to the inventor.

Description

Genus: Lavandula.
Species: stoechas.
Denomination: Lavsts 11.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of lavender known botanically as Lavandula stoechas subsp. pedunculata and hereinafter referred to by the cultivar name ‘Lavsts 11’. The new invention is a product of pollination between two Lavandula stoechas varieties, namely Lavandula ‘Somerset Mist’ (unpatented) and Lavandula ‘Gethsemane’ (unpatented). The hybrid seedling was selected by the inventor in 1997 in Christchurch, New Zealand. Because of its hybrid nature, it will be known as Lavandula ‘Lavsts 11’. The female parent of the new hybrid plant ‘Lavsts 11’ is Lavandula ‘Somerset Mist’ and male parent plant is Lavandula ‘Gethsemane’. ‘Somerset Mist’ exhibits bright green bushy foliage and pinkish-green sterile bracts which fade to a dullish purple. ‘Gethsemane’ exhibits grayish-green foliage and an open habit and flower4s with red-purple sterile bracts suffused with violet along the midrib. Thus Lavsts 11 differs from either parent in respect of foliage (Lavsts 11: mid-green), habit (Lavsts 11: semi-open) and color of sterile bracts (Lavsts 11: different from either, as described herein).
The new lavender plant ‘Lavsts 11’ is distinct and unique from all other lavenders known to the inventor due to its spikes with rich violet-blue corollas and lilac coloured sterile bracts in combination with mid-green foliage. The sterile bracts change color as they age, to a red-violet giving a two toned appearance to the bush when in flower, making them distinct from all other Lavandula stoechas cultivars.
The new invention ‘Lavsts 11’ was asexually propagated by the inventor in Christchurch, New Zealand in 1997 using soft to semi-hardwood cuttings. Since that time subsequent generations have been determined fixed, stable and true to type.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and represent the distinguishing characteristics of the new Lavandula cultivar ‘Lavsts 11’. These traits in combination distinguish ‘Lavsts 11’ from all other existing varieties of Lavandula known to the inventor. ‘Lavsts 11’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.
1. Lavandula ‘Lavsts 11’ exhibits a bushy, semi-open habit.
2. Lavandula ‘Lavsts 11’ exhibits sterile bracts that change in color from lilac to red-violet, combined with violet-blue corolla color.
3. Lavandula ‘Lavsts 11’ exhibits short to medium length peduncles.
4. Lavandula ‘Lavsts 11’ exhibits mid-green foliage.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying color drawings illustrate the overall appearance of the new cultivar ‘Lavsts 11’, showing colors as true as it is reasonably possible to obtain in colored reproduction of this type. Colors in the drawings may differ from the color values cited in the detailed botanical description, which accurately describes the actual colors of the new variety ‘Lavsts 11’. The drawings are made from 2-year-old plants grown out-of-doors in the ground in Christchurch, New Zealand.
The drawing labeled as FIG. 1 shows the entire plant from a side view perspective, illustrating the plant habit and showing the variation (darkening) of color in the sterile bracts as the flowers age.
The drawing labeled as FIG. 2 shows a close-up of the flower and sterile bracts at medium age.
Both drawings were made using conventional photographic techniques and although the colors may appear different from the actual colors due to light reflectance, they are as accurate as possible by conventional photography.
BOTANICAL DESCRIPTION OF THE PLANT
The following is a detailed description of the Lavandula cultivar named ‘Lavsts 11’. Data was collected in West Melton, Christchurch New Zealand from plants grown in the open ground and in dry conditions. Phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, without however, any difference in genotype. Color determinations are in accordance with The Royal Horticultural Society Colour Chart except where general color terms of ordinary dictionary significance are used. Color determination using The Royal Horticultural Society Colour Chart was conducted using the light box at The New Zealand Plant Variety Rights Office at Lincoln, Canterbury, New Zealand. Please note that the brown, green and violet range in these charts do not have an adequate color range to match that seen in lavender. The growing requirements are similar to the species and no disease problems have been observed.
