Abstract

A new cultivar of Lavandula angustifolia plant named ‘Walvera’ that is characterized by variegated foliage with gray-green centers and cream-white margins, a mounded, semi-open habit, and compact violet-blue flower spikes. In combination, these traits set it apart from all other existing varieties of Lavandula.

Description

BOTANICAL CLASSIFICATION
Lavandula angustifolia.
VARIETY DENOMINATION
‘Walvera’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Lavandula angustifolia and hereinafter referred to by the cultivar name ‘Walvera’. The new cultivar is a naturally occuring branch sport of Lavandula angustifolia ‘Vera’ (unpatented) and was discovered jointly by the inventors in a cultivated area of West Sussex, United Kingdom in 1993.
The new lavender plant ‘Walvera’ is distinct and unique due to its mounding, semi-open habit, gray-green leaves with cream-white marginal variegation, and violet-blue flowers. The closest comparison is the parent plant Lavandula angustifolia ‘Vera’ (unpatented). ‘Walvera’ is distinguishable from the parent plant, and all other existing varieties, by its variegated foliage.
The new invention was first asexually propagated by cuttings in West Sussex, United Kingdom by the inventors in 1995. Since that time subsequent generations have been determined fixed and stable.
SUMMARY OF THE INVENTION
The new lavender ‘Walvera’ is distinguished from all other known varieties of Lavandula, by the following characteristics:
1. Leaves with gray-green centers and cream-white variegated margins.
2. A mounded, semi-open habit.
3. Short, compact flower spikes of violet-blue flowers.
These unique traits set ‘Walvera’ apart from all other existing varieties.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying color photographs illustrate the distinguishing characteristics of the new cultivar ‘Walvera’.
Sheet 1 shows the entire plant from a side view perspective, illustrating the plant habit.
Sheet 2 illustrates the flowers on ‘Walvera’.
Photo 3 is a comparative photo illustrating the variegated foliage of ‘Walvera’ on the left, and the foliage of the parent plant Lavandula angustifolia ‘Vera’ (unpatented) on the right. All photographs are taken 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 ‘Walvera’. Data was collected in Arroyo Grande, Calif. from 12 month old plants grown in one-gallon containers. 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 1995 Royal Horticultural Society Colour Chart except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species and no disease problems have been observed.
