Abstract

A new and distinct cultivar of crapemyrtle, Lagerstroemia indica×L. fauriei, which is characterized by compact, upright-mounded growth habit and raspberry red flowers.

Description

Botanical classification: Lagerstroemia indica×L. fauriei.

Varietal denomination: ‘Gamad II’.

BACKGROUND OF THE INVENTION

The present invention relates to 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 II’.

The new crapemyrtle originated from open-pollinated seed of ‘Pocomoke’ (unpatented) a compact, rose-pink flowered introduction in 1999. ‘Gamad II’ was selected as a single raspberry red-flowered seedling with upright-mounded growth habit from 2000 seedlings of ‘Pocomoke’ by the inventor in 2002 in Dearing, Ga.

SUMMARY OF THE INVENTION

Plants of the cultivar ‘Gamad II’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as light-intensity, temperature and cultural conditions, however, without any variance in genotype.

The following characteristics have been consistently observed and, to the best knowledge of the inventor, their combination forms the unique characteristics of ‘Gamad II’ as a new and distinct cultivar.

• • 1. Compact, upright-mounded habit.
  • 2. Raspberry red flowers from early to late summer.

Plants of the new crapemyrtle have been compared to the only true genetic dwarf crape myrtles known to the inventor, Lagerstroemia ‘Chickasaw’ (unpatented), ‘Pocomoke’, and ‘Gamad I’ (U.S. Plant patent application Ser. No. 11/080,753). Comparative evaluations in containers and in the ground at Athens, Ga. showed that ‘Gamad II’ differed from ‘Chickasaw’, ‘Pocomoke’, and ‘Gamad I’ in the following characteristics:

• • 1. Plants of ‘Gamad II’ produced raspberry red flowers compared to the pure lavender-pink flowers of ‘Chickasaw’, the deep rose-pink flowers of ‘Pocomoke’, and the cherry red flowers of ‘Gamad I’.
  • 2. Plants of ‘Gamad II’ had an extremely dense upright habit compared to the rounded habits of ‘Chickasaw’, ‘Pokemoke’, and ‘Gamad I’.
  • 3. Plants of ‘Gamad I’ grew faster and filled the 11.8 liter containers faster than ‘Chickasaw’, and ‘Pocomoke’.

Asexual reproduction via tissue culture micropropagation and by traditional vegetative cuttings since June 2002 has shown that the unique characteristics of this new crapemyrtle are stable and are reproduced true-to-type in successive generations.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the unique characteristics of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ from the color values listed in the detailed botanical description which accurately describe the colors of the new crapemyrtle.

DETAILED BOTANICAL DESCRIPTION

The botanical description of ‘Gamad II’ is based on three-year-old plants, growing in 22 liter containers in an outside nursery research facility in Dearing, Ga. (USDA Zone 7b) under conditions which closely approximate commercial production. Measurements are based on the average of 10 to 20 samples, and were taken throughout the main growth period, from March through September in Dearing, Ga. Colors are based on The Royal Horticultural Society Chart, 1995 edition.

The plant has a compact, upright, mounded growth habit with a fine texture of extensive branching, attaining an average height of 61 cm. and width of 86 cm.

First year stems are square, 1.0 mm across, with an average internode length of 8 mm. They are Greyed-Orange, 166A to Greyed-Purple 183A in color, and the bark is exfoliating in strips.

Second year stems are 5 mm in diameter, with color Grey-Brown N 199B to Grey-Brown 199D. The bark exfoliates in strips.

Mature stems are up to 2.5 cm in diameter, Greyed-White 199D in color, and smooth, with very little exfoliation.

The vegetative buds are opposite to sub-opposite in arrangement, imbricate, lanceolate in shape, 2.5 mm in length and 1.5 mm in width, with pubescence, and the bud scales are Purple N 77A, Greyed-Orange 173D to 173C in color.

The mature leaf, measured in the middle section of first year stems, averages 19 mm in length and 12.5 mm in width.

The leaf is elliptical obovate, with an accuminate apex, rounded base and entire, hairy margin. The emerging leaf (April in Athens, Ga.) is Green 137A on the upper and Green 143A on the lower surface, edged with Greyed-Purple 183A. In summer (June-July), the upper surface is Green 139A and the lower surface is Green 137B. In the fall (December), the upper surface is Purple N 77 and lower Yellow-Green 146C, edged with Purple N 77.

The leaves are arranged opposite to sub-opposite on the stem and are 1 mm thick and semi-glossy. The venation is pinnate and the vein color is Yellow-Green 146D. The petiole is 2.5 mm in length and 1 mm in diameter, glabrous and Yellow-Green 146C in color.

The flower buds are 6 mm in length and 5 mm in width, round in shape with greatest diameter above the middle, and with no pubescence. They are Greyed-Red 182A to Orange-Red 34D in color.

The flowering period is from July to early October in Dearing, Ga.

The inflorescence averages 5.1 cm in length and 3.8 cm in width, and a plant in a 11.8 liter container carries 10 to 15 inflorescences. The color at emergence is Red-Purple 60B, Red-Purple 59C in full bloom, fading to Red-Purple 63A. There is an average of 9 flowers per inflorescence. The individual flower is 13 mm in length by 25 mm in width. The peduncle is glabrous and is Yellow-Green 144B and Red 46A in color.

The petals, 6 to 7 per flower, average 8 mm in length by 9 mm in width, are cordate in shape and ruffled, with an acute apex, sagittate base and ruffled undulate margin. There is no pubescence. The color of both upper and lower surfaces is red-Purple 59C and Red-Purple 60C at the claw.
