Description

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

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

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 IX’, as herein described and illustrated.

The new crapemyrtle originated from open-pollinated seed of an unpatented seedling derived from ‘Pocomoke’. ‘GAMAD IX’ was derived from plants grown 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 growth habit; 2) mildew resistance; 3) early flowering; and 4) flower color and quality. ‘GAMAD IX’ was selected in 2004.

Asexual reproduction by traditional vegetative cuttings since 2004 at Dearing, Ga. and in Athens, Ga. has shown that the distinguishing characteristics of this new crapemyrtle variety ‘GAMAD IX’ are stable and reproduced true-to-type in successive generations.

SUMMARY OF THE INVENTION

The new crapemyrtle plant variety ‘GAMAD IX’ 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 Athens, Ga., and are determined to be unique characteristics of the new crapemyrtle plant variety ‘GAMAD IX’:

    • 1. Intermediate size
    • 2. Mildew resistance
    • 3. Earlier flowering in mid to late June (USDA Zone 7)
    • 4. Abundant red-purple N74B flowers

There were no intermediate red-purple flowering varieties of crapemyrtle available for comparison. ‘GAMAD IX’ is similar in color to ‘Catawba’ (unpatented), but has a much smaller overall habit and is earlier flowering with abundant red-purple N74B flowers. The parent differs from ‘GAMAD IX’ by being more compact in habit and by having a deep pink to rose flower color.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying photographic illustrations show typical 8-year-old specimens in full bloom of the new variety ‘GAMAD IX’. The colors are as nearly true as is reasonably possible in a color representation of this type.

FIG. 1 is a photograph of the new variety ‘GAMAD IX’.

FIG. 2 is a photograph more closely illustrating the flowers of the new variety ‘GAMAD IX’.

 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, 5th edition published by The Royal Horticultural Society, London, England.

The following is a detailed description of the botanical and horticultural characteristics of the new variety ‘GAMAD IX’.
