Lagerstroemia plant named ‘Plum Magic’

Abstract

A new and distinct cultivar of lagerstroemia plant named ‘Plum Magic’, characterized by its compact, rounded to upright intermediate growth habit, plum-purple new growth, gray-green foliage in summer, fuchsia-pink flowers, and resistance to powdery mildew and Cercospora leaf spot.

Description

Genus and species of plant claimed: Lagerstroemia L.

Variety denomination: ‘Plum Magic’.

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 ‘Plum Magic’. ‘Plum Magic’ is grown primarily as an ornamental for landscape use and for use as a potted plant.

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

Plants of ‘Plum Magic’ differ from plants of the parent, ‘Gamad VI’, primarily in foliage and flower color. Plants of ‘Gamad VI’ have reddish new growth, green foliage in summer, and fuchsia flowers whereas plants of ‘Plum Magic’ have plum-purple new growth, gray-green foliage in summer, and fuchsia-pink flowers. Plants of ‘Plum Magic’ are similar to the cultivar ‘White Chocolate’ (not patented), but differ in the following ways. ‘Plum Magic’ has plum-purple new growth and fuchsia-pink flowers, whereas ‘White Chocolate’ has reddish purple new growth and white flowers. Plants of ‘Plum Magic’ are also similar to the cultivar ‘Whit III’ (U.S. Plant Pat. No. 10,319), but differ in that ‘Plum Magic’ has plum-purple new growth, gray-green mature foliage, and fuchsia-pink flowers, whereas ‘Whit III’ has ruby-red new growth, purplish green mature foliage, and bright red-purple flowers.
