USPP24193P2 - Lavandula plant named ‘Niko’ - Google Patents

Abstract

A new cultivar of Lavandula plant named ‘Niko’ that is characterized by flower spikes with purple flowers, a round shape with a compact habit, foliage that does not dieback in the center of the plant, a long period of field production and strong resistance to both Summer and Winter pythium species.

Description

Botanical classification: Lavandula angustifolia.

Variety denomination: ‘Niko’.

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 ‘Niko’.

‘Niko’ was discovered as a whole plant mutation of Lavandula ‘Grosso’. ‘Niko’ was discovered as a single plant in a bed of Lavandula ‘Grosso’ plants in 2007 in a cultivated area of Kintnersville, Pa.

Asexual reproduction of the new cultivar ‘Niko’ first occurred by terminal cuttings in 2007 in Kintnersville, Pa. 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 ‘Niko’. These traits in combination distinguish ‘Niko’ as a new and distinct cultivar apart from other existing known varieties of Lavandula.

• • 1. Lavandula ‘Niko’ exhibits flower spikes with purple flowers.
  • 2. Lavandula ‘Niko’ exhibits a compact habit.
  • 3. Lavandula ‘Niko’ exhibits a round shape.
  • 4. Lavandula ‘Niko’ exhibits foliage that does not dieback in the center of the plant.
  • 5. Lavandula ‘Niko’ exhibits a long period of field production.
  • 6. Lavandula ‘Niko’ exhibits strong resistance to both Summer and Winter pythium species.

The closest comparison cultivar is Lavandula ‘Grosso’ (not patented). ‘Niko’ is distinguishable from ‘Grosso’ by the following characteristics:

• • 1. ‘Niko’ has a more compact and rounded habit than ‘Grosso’.
  • 2. ‘Niko’ has no foliage dieback in the center. The leaves of ‘Grosso’ experience dieoff in the center of the plant.
  • 3. ‘Niko’ has a longer period of field production than ‘Grosso’.

In comparison to Lavandula ‘Hidcote’ (not patented), ‘Niko’ is distinguishable from ‘Hidcote’ by the following characteristics:

• • 1. ‘Niko’ has a smaller overall size than ‘Hidcote’.
  • 2. ‘Niko’ has shorter lateral branches than ‘Hidcote’.
  • 3. ‘Niko’ has smaller flower spikes than ‘Hidcote’.
  • 3. ‘Niko’ has lighter purple colored flowers than ‘Hidcote’.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photographs illustrate the distinguishing traits of Lavandula ‘Niko’.

The plant in the photograph of sheet 1 shows an overall view of a 1 year old plant.

Sheet 2 shows a close up view of a flower spike.

The photographs were 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 ‘Niko’. Data was collected in Mainz, Germany from 1 year old plants grown outdoors in 16 cm. diameter containers. The time of year was Summer and the average temperature was 15 to 30 degrees Centigrade during the day and 12 to 20 degrees Centigrade at night. The light level was natural light. No photoperiodic treatments or growth retards 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. ‘Niko’ 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.
