Lavandula plant named ‘Lavden 123’

Abstract

A new cultivar of Lavandula plant named ‘Lavden 123’ that is characterized by a rounded bushy habit, long narrow flower spikes, purple sterile bracts and blue corollas. These traits set it apart from all other existing varieties of Lavandula known to the inventor.

Description

Genus: Lavandula.

Species: dentata.

Denomination: Lavden 123.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of lavender known botanically as Lavandula dentata and hereinafter referred to by the cultivar name ‘Lavden 123’.

The new invention is a hybrid plant that resulted from the induced hybridization of the female parent plant Lavandula dentata and the male parent plant Lavandula dentata. Both parents were grey-leaved seedlings belonging to the breeder, and are no longer in existence. ‘Lavden 123’ was selected by the inventor in a cultivated area of Christchurch, New Zealand in January 2000.

‘Lavden 123’ grows to 70 centimeters in height and has a rounded, bushy habit. Under ideal growing conditions it is floriferous, with short to medium, uniform peduncles in a mature plant. The flower spikes are long and narrow with purple bracts and blue corollas while fertile bracts are tinged purple. ‘Lavden 123’ is susceptible to frost damage and will not grow in cold climates. Propagation can be accomplished by stem cuttings or tissue culture.

The new lavender plant ‘Lavden 123’ is distinct and unique due to its long narrow spikes, corolla color, sterile bract color, grey-green foliage and pronounced crenate leaf margins. The closest comparison plant is Lavandula dentata var. candicans.

The new invention was first asexually propagated by cuttings in 2000 by the inventor in a cultivated area of Christchurch, New Zealand. Since that time subsequent generations have been determined fixed and stable.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the distinguishing characteristics of the new lavender plant ‘Lavden 123’. These traits in combination distinguish ‘Lavden 123’ from all other existing varieties of Lavandula known to the inventor. ‘Lavden 123’ 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.

4. Lavandula ‘Lavden 123’ exhibits fertile bracts that are tinged faintly purple.

5. Under ideal growing conditions Lavandula ‘Lavden 123’ is floriferous.

6. Lavandula ‘Lavden 123’ reaches 60-70 cm in height at maturity.

7. Lavandula ‘Lavden 123’ exhibits fragrant grey-green, crenate leaves.

8. Lavandula ‘Lavden 123’ is suitable as an ornamental in a container or in the landscape.

9. Lavandula ‘Lavden’ maybe susceptible to frost damage.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawings illustrate the distinguishing characteristics of the new lavender plant ‘Lavden 123’. The drawings were made of 12-month-old plants grown out-of-doors in 14-centimeter containers.

The drawing on sheet 1 illustrates the entire plant in bloom from a side view perspective.

The drawing on sheet 2 is a close-up view of a flower spike. The drawings were 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 ‘Lavden 123’. Data was collected in Arroyo Grande, Calif. from 12-month-old plants grown in 14-centimeter containers grown out-of-doors. Color determinations are made in accordance with The 2001 Royal Horticultural Society Colour Chart except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species. Care should be taken to avoid over watering and excessively humid conditions. Under proper care no disease problems or conditions have been observed.
