Description

Botanical classification: Lavandula angustifolia.

Variety denomination: ‘150GY007’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lavandula plant botanically known as Lavandula angustifolia and hereinafter referred to by the cultivar name ‘150GY007’.

‘150GY007’ originated from a bed of open pollinated female or seed parent plants of Lavandula angustifolia ‘Thumbelina Leigh’ (U.S. Plant Pat. No. 15,231) in the spring of 2015 in Blenheim, New Zealand. The exact male or pollen parent is unknown. The resulting seeds were collected in December of 2015 and subjected to 150 grays of radiation in January of 2016. These seeds were subsequently planted and grown. The cultivar ‘150GY007’ was selected by the inventor in December of 2017 in a controlled environment as a single plant within the progeny of the stated cross in a cultivated area of Auckland, New Zealand.

Asexual reproduction of the new cultivar ‘150GY007’ first occurred by tissue culture and terminal cuttings in October of 2018 in Auckland, New Zealand. Since that time, under careful observation, the unique characteristics of the new cultivar have been uniform, stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following represent the distinguishing characteristics of the new Lavandula cultivar ‘150GY007’. These traits in combination distinguish ‘150GY007’ as a new and distinct cultivar apart from other existing varieties of Lavandula known by the inventor.

    • 1. Lavandula ‘150GY007’ exhibits a dwarf compact habit.
    • 2. Lavandula ‘150GY007’ exhibits large numbers of purple-blue flowers on short stems.
    • 3. Lavandula ‘150GY007’ exhibits a long flowering period.
    • 4. Lavandula ‘150GY007’ blooms in the first year without vernalization.

The closest comparison cultivars are Lavandula ‘Hidcote’ (not patented) and the female parent plant Lavandula ‘Thumbelina Leigh’. ‘150GY007’ is distinguishable from ‘Hidcote’ by the following characteristics:

    • 1. Lavandula ‘150GY007’ exhibits a dwarf compact habit. In comparison, the plant size of ‘Hidcote’ is larger in overall height and width.
    • 2. Lavandula ‘150GY007’ exhibits short flower spikes on short peduncles. In comparison, ‘Hidcote’ has longer flower spikes and longer peduncles.
    • 3. Lavandula ‘150GY007’ exhibits a long flowering period, spring through autumn. In comparison, ‘Hidcote’ only blooms during summer.
    • 4. Lavandula ‘150GY007’ blooms in the first year without vernalization. In comparison, ‘Hidcote’ requires vernalization.
    • 5. Lavandula ‘150GY007’ exhibits green leaves. In comparison, the leaves of ‘Hidcote’ are silver-grey.

‘150GY007’ is distinguishable from the female parent plant Lavandula ‘Thumbelina Leigh’ by the following characteristics:

    • 1. Lavandula ‘150GY007’ exhibits a dwarf compact habit. In comparison, the plant size of the female parent plant is larger in overall height and width.
    • 2. Lavandula ‘150GY007’ exhibits short peduncles. In comparison, the female parent plant has longer peduncles.
    • 3. Lavandula ‘150GY007’ exhibits a long flowering period, spring through autumn. In comparison, the female parent plant only blooms during summer.
    • 4. Lavandula ‘150GY007’ blooms in the first year without vernalization. In comparison, the female parent plant requires vernalization.
    • 5. Lavandula ‘150GY007’ exhibits dark violet-blue flower buds. In comparison, the flower buds of the female parent plant are lighter violet-blue in color.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photograph illustrates the distinguishing traits of Lavandula ‘150GY007’. The photograph shows an overall view of a 15 week old plant. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance, it is as accurate as possible by conventional photographic techniques.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new Lavandula cultivar named ‘150GY007’. Data was collected in Oxnard, Calif. from 18 week old plants grown outdoors in 9 cm. diameter containers. The time of year was Spring and the temperature range was 15-25 degrees Centigrade during the day and 8-15 degrees Centigrade at night. The light level was natural light level. No photoperiodic treatments or growth retardants were used. Color determinations are in accordance with The Royal Horticultural Society Colour Chart 2007 edition, except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species. ‘150GY007’ 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.
