Crapemyrtle plant named ‘GAMAD VIII’

Abstract

A new and distinct cultivar of crapemyrtle, ‘GAMAD VIII’, is provided. ‘GAMAD VIII’ is a Lagerstroemia indica×Lagerstroemia fauriei hybrid. The new variety is characterized by intermediate-size, upright growth habit, good mildew resistance, and earlier flowering with abundant pale pink flowers.

Description

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

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

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 VIII’, as herein described and illustrated.

The new crapemyrtle originated from open-pollinated seed of ‘Pocomoke’, an unpatented seedling. ‘GAMAD VIII’ was selected from plants being grown in a cultivated area at Dearing, Ga. from these seeds. The seedlings were planted in containers and selections were made for plants based on the following criteria: 1) intermediate, upright growth habit; 2) good mildew resistance; 3) early flowering; and 4) flower color and quality. ‘GAMAD VIII’ was selected in 2002.

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

SUMMARY OF THE INVENTION

The new crapemyrtle plant variety ‘GAMAD VIII’ 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 combination of traits of my new variety have been repeatedly observed at Dearing, Ga. and Athens, Ga., and are determined to be the unique characteristics of the new crapemyrtle plant variety ‘GAMAD VIII’:

• • 1. Intermediate size; upright growing habit
  • 2. Good mildew resistance
  • 3. Earlier flowering in mid to late June (USDA Zone 7)
  • 4. Abundant pale pink flowers

There were no intermediate-sized, pale pink flowering varieties of crapemyrtle available for comparison. ‘GAMAD VIII’ is smaller in habit than the variety ‘Whit VIII’ (U.S. Plant Pat. No. 16,616). In addition, in comparison to the variety ‘Whit VIII’, my new variety has abundant pale pink flowers, is earlier flowering, and is more Cercospora resistant. The parent of ‘GAMAD VIII’ is not currently available. However, this parent differed from ‘GAMAD VIII’ by being more compact in habit and by having a deep pink to rose flower color.
