Description

Genus and species: Lagerstroemia indica.

Variety denomination: ‘JBG 19013’.

BACKGROUND

The present disclosure relates to a new and distinct cultivar of Lagerstroemia plant, commonly known as Crape Myrtle, a shrub that is grown for use as an ornamental landscape and container plant. The new variety is known botanically as Lagerstroemia indica and will be referred to hereinafter by the cultivar name ‘JBG 19013’.

‘JBG 19013’ originated as a selected seedling from a Lagerstroemia breeding program which was started in 2008. The breeding program was conducted at the inventor's nursery in Grand Saline, Tex. The aim of the breeding program is to develop new and improved genetics of green leafed Crape Myrtles which exhibit high degrees of pest and disease resistance, high flower counts and re-flowering periods. Varieties released from the breeding program are intended to be hardy, durable, and low maintenance for the consumer. ‘JBG 19013’ was selected in 2016 as a seedling from the open-pollination of the tree form of Lagerstroemia named ‘Ruby Prince’ (unpatented) the female parent, by an unknown, unnamed male parent (unpatented) plant within a proprietary collection of green-leafed Lagerstroemia varieties. ‘JBG 19013’ was selected for its exceptionally compact shrub-like form with attractive glossy green foliage, and profuse flowering which, at peak bloom, almost covers the foliage and which lasts into fall.

‘JBG 19013’ was first asexually propagated in 2017 in a greenhouse in a nursery in Grand Saline, Tex. using softwood cuttings. ‘JBG 19013’ has been confirmed to be stable and reproduces true to type in successive generations of asexual reproduction via softwood cuttings.

SUMMARY

The following traits have been repeatedly observed and represent the distinguishing characteristics of ‘JBG 19013’. ‘JBG 19013’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, without however, any variance in genotype.

DESCRIPTION OF THE PHOTOGRAPHS

The accompanying color photographs illustrate the overall appearance of the new Lagerstroemia cultivar ‘JBG 19013’ showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Photographs were taken in July 2022 in Grand Saline, Tex. from a fifteen-month-old plant grown outdoors in a 2-gallon container, with one pinch after initial cutting establishment and without any chemical growth regulators. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describes the actual colors of the new variety ‘JBG 19013’.

COMPARISON WITH PARENTAL LINE AND KNOWN VARIETY

‘JBG 19013’ may be compared with the female parent variety, Lagerstroemia ‘Ruby Prince’ by plant size and habit. Whereas ‘Ruby Prince’ is an upright and open tree form of Lagerstroemia, ‘JBG 19013’ is a mounded dense and compact shrub form.

When ‘JBG 19013’ is compared to ‘JBG 19101’ (U.S. Plant Pat. No. 33,726), ‘JBG 19013’ has pink flowers, while ‘JBG 19101’ has red flowers. Additionally, the petals of ‘JBG 19013’ are larger than ‘JBG 19101’.
