Abstract

A new cultivar of Lavandula plant named ‘Lavang 21’ that is characterized by vibrant violet corollas and rich violet-blue calyces, large bushy habit and very long, straight peduncles. These traits set it apart from all other existing varieties of Lavandula known to the inventor.

Description

Genus: Lavandula.
Species: angustifolia.
Denomination: Lavang 21.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of lavender known botanically as Lavandula angustifolia and hereinafter referred to by the cultivar name ‘Lavang 21’. The new invention ‘Lavang 21’ is a hybrid resulting from the pollination between Lavandula angustifolia ‘Twickel Purple’ (unpatented) and an unidentified Lavandula angustifolia cultivar (unpatented). ‘Lavang 21’ was selected in a cultivated area of Christchurch, New Zealand by the inventor in 1995. The female parent plant is Lavandula angustifolia ‘Twickel Purple’ and the male parent plant is an unidentified Lavandula angustifolia cultivar.
The new lavender ‘Lavang 21’ is distinct and unique due to a bold upright habit, spike colour and striking presence. ‘Lavang 21’ is distinguishable from the parent plants by color of foliage and flower spike, shape and habit. There are no existing close comparison plants known to the inventor. ‘Lavang 21’ is distinguishable from all other lavenders known to the inventor by colour and size of spike, positioning of peduncles, foliage colour, shape of bush and upright habit.
The new invention ‘Lavang 21’ 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 ‘Lavang 21’. These traits in combination distinguish ‘Lavang 21’ from all other existing varieties of Lavandula known to the inventor. ‘Lavang 21’ 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 ‘Lavang 21’ exhibits an upright, bushy habit.
2. Lavandula ‘Lavang 21’ exhibits the color combination of vibrant violet corollas and rich violet-blue calyces on each individual flower spike.
3. Lavandula ‘Lavang 21’ exhibits particularly long and upright peduncles for a Lavandula angustifolia cultivar.
4. Lavandula ‘Lavang 21’ exhibits a striking overall height for a Lavandula angustifolia cultivar.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying color drawings illustrate the overall appearance of the new cultivar ‘Lavang 21’ 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 ‘Lavang 21’. The illustrated plants have been grown in open ground out-of-doors in Christchurch, New Zealand. No chemicals were used to treat the plants, which are 4-years-old.
The drawing labeled as FIG. 1 shows the entire plant from a side view perspective, illustrating the upright habit and the long peduncles.
The drawing labeled as FIG. 2 shows a close-up of the flower spikes.
Both drawings are made using conventional photographic techniques and although foliage 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 angustifolia cultivar named ‘Lavang 21’. Data was collected in West Melton, Canterbury, New Zealand from plants grown in the open ground and in dry conditions. The plants are 4-years-old and no chemicals were used to treat them. 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 typical of the species and no disease problems have been observed.
Botanical classification: Lavandula ‘Lavang 21’.
Species: angustifolia.
