Abstract

A new cultivar of Weigela florida, ‘Wings of Fire’, characterized by its bronze colored foliage from early summer to fall, its compact plant habit of medium stature, its large broad leaves, its red stems, and its resistance to wind and rain damage.

Description

Botanical classification: Weigela florida.

Variety denomination: ‘Wings of Fire’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Weigela florida and will be referred to hereafter by its cultivar name, ‘Wings of Fire’. ‘Wings of Fire’ is a new cultivar of old fashion weigela, a shrub grown for use as an ornamental landscape plant.

The new variety of Weigela, ‘Wings of Fire’, was selected from seedlings derived from open pollination in 2000 of an unnamed proprietary seedling of Weigela florida in the Inventor's garden in Booskoop, The Netherlands. ‘Wings of Fire’ was selected as a single unique plant from the resulting seedlings in summer of 2004.

Asexual reproduction of the new cultivar was first accomplished by the Inventor using softwood stem cuttings in 2004 in Boskoop, The Netherlands. The characteristics of this cultivar have been determined to be stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar as grown outdoors in a trial plot for five years in Boskoop, The Netherlands. These attributes in combination distinguish ‘Wings of Fire’ as a unique cultivar of Weigela.

• • 1. ‘Wings of Fire’ exhibits a compact plant habit of medium stature; reaching about 75 cm in height.
  • 2. ‘Wings of Fire’ exhibits large, broad leaves.
  • 3. ‘Wings of Fire’ exhibits bronze colored foliage from early summer to fall with color intensified with sun exposure.
  • 4. ‘Wings of Fire’ exhibits red colored stems.
  • 5. ‘Wings of Fire’ exhibits good resistance to wind and rain damage.

The female parent, a proprietary seedling, differs from ‘Wings of Fire’ in having bronze foliage only in fall and in having a second year habit that is less compact. ‘Wings of Fire’ can be most closely compared to the cultivars ‘Alexandra’ (U.S. Plant Pat. No. 10,772) and ‘Elvera’ (U.S. Plant Pat. No. 12,217). ‘Alexandra’ differs from ‘Wings of Fire’ in being taller in height (reaching about 1.5 m in height), in having a less compact plant habit and in having foliage that is darker bronze in color with distinct green veins. ‘Elvera’ differs from ‘Wings of Fire’ in having a dwarf plant habit (reaching about 22 cm in height) and in having foliage that is dark purple in color.
