| Abstract: |
A new cultivar of Lavandula plant named `Lavang 38` that is characterized by vibrant violet-blue corollas, and low-growing compact bushy habit. These traits set it apart from all other existing varieties of Lavandula known to the inventor. |
| Claim: |
I claim:
1. A new and distinct variety of Lavandula plant named `Lavang 38` as described and illustrated. |
| Description: |
Genus: Lavandula.
Species: angustifolia.
Denomination: Lavang 38.
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 38`. The new invention is a selected seedling from a group of seedlingsproduced by the open pollination between Lavandula angustifolia `Midhall` (unpatented) and an unidentified Lavandula angustifolia cultivar. The female parent plant is `Midhall` and the male parent plant is an unidentified cultivar of Lavandulaangustifolia. `Lavang 38` was discovered by the inventor in a cultivated area of Christchurch, New Zealand in 1995.
The new lavender `Lavang 38` is distinct and was selected for compact bushy habit, flower spike colour, and striking presence. `Lavang 38` is distinguishable from the parent plant, and all other existing varieties known to the inventor, bycolour and size of spike, positioning of peduncles, foliage colour, shape of plant, and low growing habit.
The new variety `Lavang 38` was first 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 38`. These traits in combination distinguish `Lavang 38` from all other existing varieties of Lavandulaknown to the inventor. `Lavang 38` 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 38` exhibits a compact, bushy habit. 2. Lavandula `Lavang 38` exhibits a combination of violet-blue corollas and violet calyx colour. 3. Lavandula `Lavang 38` exhibits a low height for a Lavandula angustifolia cultivar. 4. Lavandula `Lavang 38` is particularly floriferous when pruned and fed correctly. 5. Lavandula `Lavang 38` is hardy to USDA Zone 5.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying color drawings illustrate the overall appearance of the new cultivar `Lavang 38` showing colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the drawings may differ from thecolor values cited in the detailed botanical description, which accurately describe the actual colors of the new variety `Lavang 38`. The drawings illustrate 3-year-old plants growing out-of-doors in the ground in Christchurch, New Zealand.
The drawing labeled as
FIG. 1 shows the entire plant from an above and side view perspective, illustrating the plant habit and the flower spikes while in bud.
The drawing labeled as
FIG. 2 shows a close-up on the flower spike, with individual flower buds and flowers open.
Both drawings are made using conventional photographic techniques and although colors may appear different from actual colors due to lightreflectance, they are as accurate as possible by conventional photography.
BOTANICAL DESCRIPTION OF THE PLANT
The following is a detailed description of the new Lavandula angustifolia cultivar named `Lavang 38`. Data was collected in West Melton, Canterbury, New Zealand from plants grown in the open ground and in dry conditions. Phenotypic differencesmay 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 termsof 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 thatthe 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. Botanical classification: Lavandulaangustifolia `Lavang 38`. Species: angustifolia. Common name: Lavender. Parentage: `LAVANG 38` is a hybrid seedling that resulted from open pollination of the following parent plants: Female parent plant.--Lavandula angustifolia `Midhall`(unpatented). Male parent plant.--Unidentified Lavandula angustifolia cultivar. Type: Aromatic perennial shrub. Use: Front of border, low hedging, potted or feature plant. Growth rate: Average for a Lavandula angustifolia cultivar. Habit: Bushycompact habit with ascending flower spikes. Shape: Round. Height: 40 cm in height. Spread: Approximately 40 cm in width. Hardiness: USDA Zone 5. Disease susceptibility: In common with the species Lavandula angustifolia, Lavang 38 may be susceptibleto Lavender leafspot (Septoria lavandulae) or to bacterial blast (pseudomonas syringae) or to Phoma if conditions are very wet or if plants are overwatered. Lavang 38 is not considered unusually or, in comparison with other known cultivars of thespecies, differently susceptible to any of these pathogens whose occurrence is more associated with adverse growing conditions. Propagation method: Vegetative cuttings, tissue culture. Root system: Fibrous. Soil: Plant in well-drained soil. Lightlevels: Plant in full sun. Special needs: Prune after flowering to maintain shape -- will continue to flower if left but will need pruning prior to winter. Pruning will enhance number of flowers the following season. Time to initiate roots: 21 to 36days are needed to develop roots on an unrooted cutting. Time to develop to a one-gallon: 6 months is needed to produce a finished 1-gallon container from a rooted cutting. Branching habit: Foliage branched, erect, upright and compact. Seasonalinterest: Vibrant violet flower spikes (large corollas) in June and July. Stem: Stem shape.--Square. Stem surface.--Main stems can be glabrous or puberulent, side branches are puberulent. Stem color.--165D (pale orange-brown). Stem size.--1-3 mm indiameter. Foliage: Arrangement.--Semi-upright stems with whorls of leaves, arranged opposite along stem. A basal pair of leaves subtend each whorl of leaves. Regular arrangement of leaves along stems. Leaf division.--Simple. Apices.--Obtuse. Base.--Truncate. Margins.--Entire and markedly revolute.
