Abstract

A new cultivar of Lavandula plant named ‘Lavsts 08’ that is characterized by burgundy-purple sterile bracts and low, compact bushy habit. These traits set it apart from all other existing varieties of Lavandula known to the inventor.

Description

Genus: Lavandula.
Species: stoechas.
Denomination: Lavsts 08.
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 08’. The new invention is a product of pollination between two Lavandula stoechas varieties and was discovered in a cultivated area of Canterbury, New Zealand by the inventor in 1997. Because of its hybrid nature, it will be known as Lavandula ‘Lavsts 08’. The female parent plant is an unidentified cultivar of Lavandula stoechas (unpatented) and the male parent plant is an unidentified cultivar of Lavandula stoechas (unpatented).
The new Lavender plant ‘Lavsts 08’ was selected for its distinct and unique low compact growth habit, spike colour, and sterile bract colour. ‘Lavsts 08’ is distinguishable from the parent plants by size of the plant and color of the sterile bracts. There are no comparison plants known to the inventor.
‘Lavsts 08’ was asexually propagated by the inventor in Christchurch, New Zealand in 1998 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 lavender cultivar ‘Lavsts 08’. These traits in combination distinguish ‘Lavsts 08’ from all other existing varieties of Lavandula known to the inventor. ‘Lavsts 08’ 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 08’ exhibits a low, compact, bushy habit.
2. Lavandula ‘Lavsts 08’ exhibits burgundy-purple sterile bracts.
3. Lavandual ‘Lavsts 08’ exhibits dark violet spikes.
4. Lavandula ‘Lavsts 08’ exhibits lush green foliage.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying color drawings illustrate the overall appearance of the new cultivar ‘Lavsts 08’ showing colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the drawings may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety ‘Lavsts 08’.
The drawing labeled as FIG. 1 is a close-up view of a block of 6-month-old plants with first flowers. The plants shown were grown outside, under light shade, in Auckland, New Zealand.
The drawing labeled as FIG. 2 is a close-up view of mature flowers on a plant, approximately 9 months old, grown outside in Encinitas, Calif.
Both drawings are made using conventional photographic techniques and although colors may appear different from 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 08’. Data was collected in West Melton, Canterbury, New Zealand from 6-month-old 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.
