Description

Genus: LAVANDULA.

Species: stoechas.

Denomination: ‘VIOLET LACE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of lavender known botanically as Lavandula stoechas and hereinafter referred to by the cultivar name ‘VIOLET LACE’.

The new Lavandula cultivar named ‘VIOLET LACE’ is one individual selection in the Australian lavender ‘Lace Series’ that resulted from a formal breeding program. The breeding program was established in November 2001 and conducted by the inventor at the inventor's nursery in Victoria, Australia. The inventor, a specialist of the genus Lavandula, selected ‘VIOLET LACE’ in September 2003. Selection was based on the criterion of strong commercial sales potential due to early flowering, hardiness, and strong landscape performance.

‘VIOLET LACE’ is a selection arising from the controlled cross-pollination of Lavandula stoechas ‘Kew Red’ (unpatented) as the female parent and Lavandula stoechas ‘Pukehou’ (unpatented) as the male parent. Cross-pollination of the parent plants took place in Park Orchards, Victoria, Australia. From this cross a seedling population was raised in February 2002, and grown to flowering maturity in 140 mm. containers in September 2002. From these seedlings the final selection was made.

‘VIOLET LACE’ is a perennial suitable for use in the landscape. Cultural requirements include full sun, adequate but not excess water, and well-draining soil. Mature height and breadth is 70 cm. ‘VIOLET LACE’ exhibits upright, open habit, scented green foliage, and scented red-purple flower spikes in spring and summer. Sterile bracts are small and greyed-purple in color.

The traits that distinguish ‘VIOLET LACE’ from all other Lavandula known to the inventor are early flowering, sterile bract size, plant habit, peduncle length, and sterile bract color. ‘VIOLET LACE’ is distinguishable from the female parent by length and color of sterile bracts. An individual sterile bract of ‘VIOLET LACE’ is long and mid-violet in color when compared to the sterile bract of ‘Kew Red’, which is short and pink. ‘VIOLET LACE’ is distinguishable from the male parent by medium peduncle length, dense habit and dark mid-violet sterile bracts. In comparison, ‘Pukehou’ has a long peduncle, medium to sparse plant density, and dark violet sterile bracts.

The new Lavandula cultivar named ‘VIOLET LACE’ was first asexually propagated by the inventor in 2003. Asexual propagation was accomplished at the inventor's nursery in Victoria, Australia using tip cuttings. Since that time ‘VIOLET LACE’ has been determinated stable, and reproduces true to type in successive generations of asexual propagation.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the distinguishing characteristics of the new Lavandula cultivar named ‘VIOLET LACE’. These traits in combination distinguish ‘VIOLET LACE’ from all other existing varieties of Lavandula known to the inventor. ‘VIOLET LACE’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, without however, any variance in genotype.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawings illustrate the overall appearance of the new Lavandula cultivar named ‘VIOLET LACE’ showing the colors as true as it is reasonably possible to obtain in color reproductions of this type. Color in the drawings may differ from the color values cited in the detailed botanical description, which accurately describe the actual color of the new Lavandula, variety named ‘VIOLET LACE’. The drawings were made of 9-month-old plants greenhouse grown in 16 cm. containers.

The drawing labeled FIG. 1 depicts the plant in bloom from a side perspective.

The drawing labeled FIG. 2 depicts a close-up view of the flower spike. Drawings were made using conventional techniques and although the leaf and flower color of ‘VIOLET LACE’ may appear different from the actual color due to light reflectance, they are as accurate as possible by conventional photography.
