Abstract

A new cultivar of Lavandula plant named ‘Lavsts 15’ that is characterized by upright semi-open habit, grey-green foliage, and white sterile bracts combined with 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 15.
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 15’. The new invention is a hybrid plant that resulted from the pollination between two Lavandula stoechas varieties, namely Lavandula ‘Gethsemane’ and Lavandula stoechas subsp. pedunculata and was selected in Christchurch, New Zealand by the inventor in 1996. Because of its hybrid nature, the instant plant will be known as Lavandula ‘Lavsts 15’. The female parent is Lavandula ‘Gethsemane’ (unpatented) and the male parent plant is an unidentified cultivar of Lavandula stoechas subsp. pedunculata (unpatented).
The new lavender cultivar ‘Lavsts 15’ is distinct and unique due to its long peduncles that terminate in bicolor spikes, combined with grey-green foliage. There are no comparison plants, known to the inventor, that resemble the instant plant. ‘Lavsts 15’ is distinguishable from both parent plants by the color of foliage, spike and sterile bracts.
The new invention ‘Lavsts 15’ was asexually propagated by the inventor in Christchurch, New Zealand in 1996 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 15’. These traits in combination distinguish ‘Lavsts 15’ from all other existing varieties of Lavandula known to the inventor. ‘Lavsts 15’ 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 15’ exhibits an upright, semi-open habit.
2. The sterile bracts and corollas of Lavandula ‘Lavsts 15’ in combination exhibit the colors white and violet blue.
3. Lavandula ‘Lavsts 15’ exhibits long tomentose, pale green peduncles.
4. Lavandula ‘Lavsts 15’ exhibits grey-green foliage.
5. Lavandula ‘Lavsts 15’ exhibits 4-8 sterile bracts per flower spike.
6. Lavandula ‘Lavsts 15’ exhibits tinges of pink coloring on the sterile bracts as the flower spikes age.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying color drawings illustrate the overall appearance of the new cultivar ‘Lavsts 15’, showing colors as true as it is reasonablely 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 describes the actual colors of the new variety ‘Lavsts 15’. The plants are 6-months-old and grown out-of-doors in 1-liter containers in Christchurch, New Zealand. No chemicals were used to treat the plants.
The drawing labeled as FIG. 1 shows a mass of entire plants from an above perspective.
The drawing labeled as FIG. 2 shows a close-up of the flower spikes and sterile bracts.
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 15’. Data was collected in West Melton, Canterbury, New Zealand from plants grown in the open ground and in dry conditions. The plants are 6-months-old and received no chemical treatments. 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 ranges 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.
