plant named ‘Purple Magic’

Abstract

A new and distinct cultivar of Lagerstroemia plant named ‘Purple Magic’, characterized by its compact, rounded to upright intermediate growth habit, reddish new growth, lustrous dark green foliage in summer, purple flowers, and resistance to powdery mildew and Cercospora leaf spot.

Description

Genus and species of plant claimed: Lagerstroemia hybrid.

Variety denomination: ‘Purple 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 ‘Purple Magic’. ‘Purple Magic’ is grown primarily as an ornamental for landscape use and for use as a potted plant.

‘Purple Magic’ originated from open-pollinated seed of an unnamed and unpatented seedling known to the inventor as 16-02 growing in Watkinsville, Ga. The cultivar ‘Purple 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 ‘Purple 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 ‘Purple 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 ‘Purple Magic’. These characteristics in combination distinguish ‘Purple Magic’ as a new and distinct cultivar: 1. Compact, rounded to upright intermediate growth habit; 2. Reddish new growth; 3. Lustrous dark green foliage in summer; 4. Purple flowers; 5. Resistance to powdery mildew and Cercospora leaf spot.

Plants of ‘Purple Magic’ differ from plants of the parent, 16-02 (unpatented), primarily in growth habit, flower color, and disease resistance. Plants of 16-02 have a large upright spreading growth habit, pale lavender-purple flowers, and are moderately susceptible to powdery mildew and Cercospora leaf spot, whereas plants of ‘Purple Magic’ have a more compact, rounded to upright intermediate growth habit, purple flowers, and are resistant to powdery mildew and Cercospora leaf spot. ‘Purple Magic’ can be compared to the cultivar ‘Catawba’ (not patented), but differs in size, growth habit, and flower color. ‘Purple Magic’ has a smaller, rounded to upright growth habit and darker purple flowers, whereas ‘Catawba’ has a larger globose growth habit and lighter purple flowers. ‘Purple Magic’ can be compared to the cultivar ‘GAMAD IX’ (U.S. Plant Pat. No. 23,560), but differs in size, growth habit, and flower color. ‘Purple Magic’ has a larger, rounded to upright growth habit and darker purple flowers, whereas ‘GAMAD IX’ has a smaller, rounded to broad-rounded growth habit and lighter purple flowers.
