Lagerstroemia plant named ‘PIILAG B3’

Abstract

A new and distinct cultivar of lagerstroemia plant named ‘PIILAG B3’, characterized by its compact, rounded intermediate growth habit, reddish purple new growth, lustrous dark green foliage in summer, fuchsia-pink flowers, and resistance to powdery mildew and Cercospora leaf spot.

Description

Genus and species of plant claimed: Lagerstroemia indica×L. fauriei.

Variety denomination: ‘PIILAG B3’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lagerstroemia plant, botanically known as Lagerstroemia indica×L. fauriei, commonly known as crapemyrtle, and hereinafter referred to by the cultivar name ‘PIILAG B3’. ‘PIILAG B3’ is grown primarily as an ornamental for landscape use and for use as a potted plant.

‘PIILAG B3’ originated from open-pollinated seed of Lagerstroemia indica×L. fauriei ‘Gamad VI’ (U.S. Plant Pat. No. 22,161) growing in Watkinsville, Ga. The cultivar ‘PIILAG B3’ originated in 2008 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 B3’ by stem cuttings in Watkinsville, Ga. since 2009 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 B3’ 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 B3’. These characteristics in combination distinguish ‘PIILAG B3’ as a new and distinct cultivar: 1. Compact, rounded intermediate growth habit; 2. Reddish purple new growth; 3. Lustrous dark green foliage in summer; 4. Fuchsia-pink flowers; 5. Resistance to powdery mildew and Cercospora leaf spot.

Plants of ‘PIILAG B3’ differ from plants of the parent, ‘Gamad VI’, primarily in growth habit, flower color, and time of flowering. Plants of ‘Gamad VI’ have a compact, mounded growth habit and produce deep red and purple flowers in early summer, whereas plants of ‘PIILAG B3’ have an overall larger, compact, rounded intermediate growth habit and fuchsia-pink flowers in mid-summer.

Plants of ‘PIILAG B3’ can be compared to the cultivar ‘Whit III’ (U.S. Plant Pat. No. 10,319), but differ in overall size, foliage color, and flower color. Plants of ‘PIILAG B3’ have a compact, rounded intermediate growth habit, foliage that emerges reddish purple and matures to lustrous dark green, and fuchsia-pink flowers, whereas plants of ‘Whit III’ have an overall larger growth habit, ruby red new growth that matures to purplish green, and red-purple flowers.
