Crapemyrtle plant named ‘Gamad VII’

Abstract

A new and distinct cultivar of crapemyrtle, ‘Gamad VII’ is provided. ‘Gamad VII’ is a Lagerstroemia indica×Lagerstroemia fauriei, which is characterized by compact growth habit, high Cercospora resistance, and early July flowering with abundant true pink flowers.

Description

Latin name of the genus and species of the plant claimed: ‘Gamad VII’ is a crapemyrtle plant that is a Lagerstroemia hybrid.

Variety denomination: The new crapemyrtle plant claimed is of the variety denominated ‘Gamad VII’.

BACKGROUND OF THE INVENTION

The present invention relates to the discovery of a new and distinct cultivar of the ornamental flowering shrub Lagerstroemia indica×Lagerstroemia fauriei, commonly known as crapemyrtle, and herein referred to by the varietal denomination ‘Gamad VII’, as herein described and illustrated.

The new crapemyrtle plant variety ‘Gamad VII’ originated from open-pollinated seed of ‘Pocomoke’ (unpatented), a compact, rose-pink flowered introduction in 1999 from the United States National Arboretum (USDA). ‘Gamad VII’ was derived from plants grown in 2001 at Athens, Ga. from seed collected from open pollinated ‘Pocomoke’ plants. The seedlings were planted in containers at Dearing, Ga. and selected on the basis of the following criteria: 1) compact habit; 2) mildew resistance; 3) early flowering; and 4) flower color and quality. The new variety, ‘Gamad VII’, was selected in 2003 at Dearing, Ga.

Asexual reproduction by traditional vegetative cuttings since 2003 at Dearing, Ga. has shown that the distinguishing characteristics of this new crapemyrtle variety, ‘Gamad VII’, are stable and reproduce true-to-type in successive generations.

SUMMARY OF THE INVENTION

The new crapemyrtle plant variety ‘Gamad VII’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

Throughout this specification, color names beginning with a small letter signify that the name of that color, as used in common speech, is aptly descriptive. Color names beginning with a capital letter designate values based upon The R.H.S. Colour Chart, 5^th edition published by The Royal Horticultural Society, London, England.

The following traits have been repeatedly observed in Dearing, Ga., and are determined to be the unique characteristics of the new crapemyrtle plant variety ‘Gamad VII’:

• • 1. Compact growth habit
  • 2. High Cercospora resistance
  • 3. Early July flowering with abundant deep red-purple flowers

The new variety ‘Gamad VII’ can be compared to ‘Gamad V’ (U.S. Plant Pat. No. 17,411), a compact pink flowering variety. ‘Gamad VII’ is slightly larger than ‘Gamad V’, with a looser, finer textured structure.

‘Gamad VII’ can also be compared to ‘Pocomoke’. ‘Gamad VII’ possesses greater fungal resistance relative to ‘Pocomoke’. The flowers of ‘Gamad VII’ are more abundant than ‘Pocomoke’ and are pink (Red-purple 68B) whereas the flowers of ‘Pocomoke’ are bubble-gum pink (Red-purple 73B, fading to Violet 84B).

BRIEF DESCRIPTION OF THE DRAWINGS
