Description

Latin name of the genus and species of the plant claimed: Lavandula angustifolia.

Varietal denomination: ‘LAAZ0001’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a Lavandula, botanically known as Lavandula angustifolia, and hereinafter referred to by the variety name ‘LAAZ0001’.

‘LAAZ0001’ is a product of a planned breeding program. The new cultivar has violet-blue flowers, an early season flowering response, individual flowers stay open all day and plant continuously flowers through the entire summer season.

‘LAAZ0001’ originates from a self-pollination made in August 2005 in a controlled breeding program in Enkhuizen, Netherlands. The female parent was an unpatented, proprietary plant identified as ‘G3012-13’ with lighter blue color, erect growth with less branching.

The resulting seeds were sown in the early spring of 2006 and ‘LAAZ0001’ was selected as one flowering plant within the progeny of the stated cross in July 2006 in a controlled environment in Enkhuizen, Netherlands.

The first act of asexual reproduction of ‘LAAZ0001’ was accomplished when vegetative cuttings were propagated from the initial selection in August 2006 in a controlled environment in Enkhuizen, Netherlands.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in the spring of 2007 in Enkhuizen, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘LAAZ0001’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘LAAZ0001’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length.

A Plant Breeder's Right for this cultivar was applied for in the European Union on Apr. 7, 2011, #2011/0899. ‘LAAZ0001’ has not been made publicly available more than one year prior to the filing of this application.

The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Lavandula as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘LAAZ0001’ with colors being as true as possible with an illustration of this type. The photographic drawing shows a flowering plant of the new variety and a close-up of the inflorescence.

 DETAILED BOTANICAL DESCRIPTION

The plant descriptions and measurements were taken in Enkhuizen, Netherlands in early July 2011 using plants growing in an outdoor container trial in 13 cm pots. These plants were approximately 20 weeks of age.

The photographs were taken in mid July 2011. The plants used for the photographs were about 24 weeks of age and were grown in a greenhouse trial in Enkhuizen, Netherlands.
