Lagerstroemia plant named ‘PIILAG-V’

Abstract

A new and distinct cultivar of lagerstroemia plant named ‘PIILAG-V’, characterized by its compact, rounded, intermediate growth habit, dark maroon-purple foliage, dark pink flowers, and resistance to powdery mildew and Cercospora leaf spot.

Description

Genus and species of plant claimed: Lagerstroemia L.

Variety denomination: ‘PIILAG-V’.

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-V’. ‘PIILAG-V’ is grown primarily as an ornamental for landscape use and for use as a potted plant.

‘PIILAG-V’ originated in 2010 from open-pollinated seed of Lagerstroemia ‘Chocolate Mocha’ (U.S. Plant Pat. No. 21,540) growing in Watkinsville, Ga. The cultivar ‘PIILAG-V’ originated and was selected in a cultivated environment in Watkinsville, Ga. from the progeny of this open-pollination by continued evaluation for growth habit and foliage and flower characteristics.

Asexual reproduction of ‘PIILAG-V’ by stem cuttings in Watkinsville, Ga. since 2011 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-V’ 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-V’. These characteristics in combination distinguish ‘PIILAG-V’ as a new and distinct cultivar: 1. Compact, rounded, intermediate growth habit; 2. Dark maroon-purple foliage; 3. Dark pink flowers; 4. Resistance to powdery mildew and Cercospora leaf spot.

Plants of ‘PIILAG-V’ differ from plants of the parent, ‘Chocolate Mocha’, primarily in growth habit, foliage, and flower color. Plants of ‘PIILAG-V’ have a compact, rounded, intermediate growth habit, dark maroon-purple foliage, and dark pink flowers, whereas plants of ‘Chocolate Mocha’ have an upright growth habit, dark brown/red-purple foliage, and lighter pink flowers.

Plants of ‘PIILAG-V’ can be compared to plants of Lagerstroemia ‘PIILAG-IV’ (U.S. Plant patent application Ser. No. 13/998,271) but differ in growth habit and flower color. Plants of ‘PIILAG-V’ have compact to rounded, intermediate growth habit and dark pink flowers, whereas plants of ‘PIILAG-IV’ have upright growth habit and red flower buds that open to white flowers.

Plants of ‘PIILAG-V’ can also be compared to plants of Lagerstroemia ‘Coral Magic’ (U.S. Plant Pat. No. 23,922). ‘Coral Magic's’ new growth red leaf color is lighter than that of ‘PIILAG-V’. ‘Coral Magic’ generally has dark green leaves that fade through the growing season compared to that of ‘PIILAG-V’ that has dark maroon-purple foliage color. ‘Coral Magic’ has salmon-pink flowers compared to ‘PIILAG-V’ that has dark maroon-purple flowers.
