plant named ‘AZ’

Abstract

A new cultivar of Weigela named ‘AZ’ that is characterized by its dense and compact plant habit, its flowers that are light grey-purple in color, its young foliage that is grey-purple to brown in color, and its floriferous blooming habit.

Description

Botanical classification: Weigela hybrid.

Variety denomination: ‘AZ’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Weigela of hybrid origin and will be referred to hereafter by its cultivar name, ‘AZ’. ‘AZ’ represents a new cultivar of Weigela, a deciduous shrub grown for landscape use.

‘AZ’ was discovered by the Inventor as a chance seedling in a field plot that had been planted with seed collected from numerous open pollinated unnamed and named plants of Weigela in Hazerswoude-Dorp, The Netherlands in June of 2014. The parentage is unknown.

Asexual propagation of the new cultivar was first accomplished by softwood stem cuttings by the Inventor in July of 2015 in Hazerswoude-Dorp, The Netherlands. Asexual propagation by softwood stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the characteristics of the new cultivar. These attributes in combination distinguish ‘AZ’ as a unique cultivar of Weigela.

• • 1. ‘AZ’ exhibits a dense and compact plant habit.
  • 2. ‘AZ’ exhibits flowers that are light grey-purple in color.
  • 3. ‘AZ’ exhibits young foliage that is grey-purple to brown in color.
  • 4. ‘AZ’ exhibits a floriferous blooming habit.

‘AZ’ can be most closely compared to the Weigela florida ‘Velda’ (U.S. Plant Pat. No. 26,842) and Weigela hybrid ‘Courtacad1’ (U.S. Plant Pat. No. 22,766). ‘Velda’ and ‘Courtacad1’ are both similar to ‘AZ’ in having a compact plant habit. ‘Velda’ and ‘Courtacad1’ both differ from ‘AZ’ in having foliage that is darker in color, flowers that are whiter in color, and being taller in height.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

The Applicant asserts that no publications or advertisements relating to sales, offers for sale, or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor. The Applicant claims a prior art exemption under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date. Disclosure include but may not be limited to website and facebook postings by Blooming Easy and listed in a plant database by The National Gardening Association.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrates the overall appearance and distinct characteristics of the new Weigela. The photographs were taken of a six-year-old plant as grown outdoors in a trial field in Hazerswoude-Dorp, The Netherlands. The plants had been pruned (back to 10 cm) in early spring (3 months prior to the description).

The photograph in FIG. 1 provides an overall view of the growth habit of ‘AZ’.

The photograph in FIG. 2 provides a close-up view of the flowers of ‘AZ’.

The photograph in FIG. 3 provides a close-up view of the maturing foliage of ‘AZ’.

The photograph in FIG. 4 provides a close-up view of the young foliage of ‘AZ’.

The colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Weigela.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of six-year-old plants as grown outdoors in a trial field in Hazerswoude-Dorp, The Netherlands. The plants had been pruned (back to 10 cm) in early spring (3 months prior to the description). Phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions. The color determination is in accordance with The 2015 Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
