Crapemyrtle plant named ‘Gamad VI’

Abstract

A new and distinct cultivar of crapemyrtle, ‘Gamad VI’, is provided. ‘Gamad VI’ is a Lagerstroemia indica×Lagerstroemia fauriei hybrid, which is characterized by compact growth habit, mildew resistance, and early flowering with abundant deep red and purple flowers.

Description

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

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

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 hereafter referred to by the varietal denomination ‘Gamad VI’, as herein described and illustrated.

The new crapemyrtle originated from open-pollinated seed of ‘Pocomoke’ (unpatented), a compact, rose-pink flowered introduction in 1999 from the United States National Arboretum (USDA). ‘Gamad VI’ was derived from plants grown in 2001 at Athens, Ga. from seed collected from open pollinated ‘Pocomoke’ plants. The seedlings were planted in containers and selections were made at Dearing, Ga. for plants based on the following criteria: 1) compact habit; 2) mildew resistance; 3) early flowering; and 4) flower color and quality. ‘Gamad VI’ was selected in 2002.

Asexual reproduction by traditional vegetative cuttings since 2002 at Dearing, Ga. has shown that the distinguishing characteristics of this new crapemyrtle variety ‘Gamad VI’ are stable and reproduced true-to-type in successive generations.

SUMMARY OF THE INVENTION

The new crapemyrtle plant variety ‘Gamad VI’ 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.

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

• • 1. Compact-mounded habit
  • 2. Mildew resistance
  • 3. Early flowering in late June
  • 4. Abundant deep red and purple flowers

There were no compact purple flowering varieties of crapemyrtle available for comparison. ‘Gamad VI’ is similar in size to ‘Pocomoke’, but has larger leaves and is earlier in flowering with abundant deep red/purple flowers compared to the pink flowers of ‘Pocomoke’. ‘Gamad VI’ possesses greater resistance to mildew relative to ‘Pocomoke’.

BOTANICAL DESCRIPTION

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.
