Lagerstroemia plant named ‘PIILAG-II’

Abstract

A new and distinct cultivar of lagerstroemia plant named ‘PIILAG-II’, characterized by its compact, rounded growth habit, reddish new growth and dark green foliage in summer, neon-rose flowers, and resistance to powdery mildew and Cercospora leaf spot.

Description

Genus and species of plant claimed: Lagerstroemia L.

Variety denomination: ‘PIILAG-II’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lagerstroemia plant, botanically known as Lagerstroemia L., commonly known as crapemyrtle, and hereinafter referred to by the cultivar name ‘PIILAG-II’.

The new Lagerstroemia plant originated in 2006 from open-pollinated seed of ‘Gamad I’ (U.S. Plant Pat. No. 16,917). The cultivar ‘PIILAG-II’ originated and was discovered in a cultivated environment in Dearing, Ga.

Asexual reproduction of the new cultivar since 2007 by stem cuttings in Watkinsville, Ga. has shown that all the unique features of this new Lagerstroemia, as herein described, are stable and reproduced true-to-type through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

Plants of the new cultivar ‘PIILAG-II’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with changes in light, temperature, soil and rainfall without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘PIILAG-II’. These characteristics in combination distinguish ‘PIILAG-II’ as a new and distinct cultivar: 1. Compact, rounded growth habit; 2. Reddish new growth and dark green foliage in summer; 3. Neon-rose flowers; 4. Resistance to powdery mildew and Cercospora leaf spot.

Plants of the new Lagerstroemia ‘PIILAG-II’ differ from plants of the parent, ‘Gamad I’, primarily in flower color and growth habit, as plants of ‘Gamad I’ have cherry red flowers, and an overall tighter and more compact growth habit, whereas plants of ‘PIILAG-II’ have neon-rose flowers and an overall larger and looser growth habit.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the flower and foliage characteristics and the overall appearance of the new Lagerstroemia, showing the colors as true as it is reasonably possible to obtain in color reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Lagerstroemia.
