plant named ‘Baillagone’

Abstract

A new cultivar of Lagerstroemia plant named ‘Baillagone’ that is characterized by its oval shaped, compact, tight plant habit of intermediate stature, its foliage that is dark reddish green in color in summer, its flower buds that are yellow-green and tinged with red at apex, its flowers that are large in size and white in color, and its high resistance to powdery mildew and Cercospora leaf spot.

Description

Botanical classification: Lagerstroemia hybrid.

Variety denomination: ‘Baillagone’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lagerstroemia of hybrid origin. The new Lagerstroemia will hereafter be referred to by its cultivar name, ‘Baillagone’. ‘Baillagone’ is a new cultivar of crape myrtle grown for use as an ornamental landscape plant.

The new cultivar was derived from a controlled breeding program conducted by the Inventors in Watkinsville, Ga. The objective of the breeding program is to develop a new cultivar of crape myrtle with an intermediate plant habit, dark foliage and white flowers.

‘Baillagone’ arose from a cross-made in 2012 between Lagerstroemia ‘PIILAG-IV’ (U.S. Plant Pat. No. 25,478) as the female parent and Lagerstroemia ‘PIILAG-I’ (U.S. Plant Pat. No. 23,168) as the male parent. ‘Baillagone’ was selected as a single unique plant in 2014 from amongst the seedlings derived from the above cross.

Asexual propagation of the new cultivar was first accomplished by semi-hardwood stem cuttings by one of the Inventors in Watkinsville, Ga. in 2014. Asexual propagation by semi-hardwood stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Baillagone’ as a unique cultivar of Lagerstroemia.

• 1. ‘Baillagone’ exhibits an oval shaped, compact, and tight plant habit of intermediate stature.
• 2. ‘Baillagone’ exhibits foliage that is dark reddish green in color in summer.
• 3. ‘Baillagone’ exhibits flower buds that are yellow-green and tinged with red at apex.
• 4. ‘Baillagone’ exhibits flowers that are large in size and white in color.
• 5. ‘Baillagone’ exhibits high resistance to powdery mildew and Cercospora leaf spot.

‘PIILAG-IV’, the female parent of ‘Baillagone’, differs from ‘Baillagone’ in having an upright growth habit, dark maroon purple foliage and red flower buds that open white with hints of pink in color. ‘PIILAG-I’ , the male parent of ‘Baillagone’, differs from ‘Baillagone’ in having a rounded and dwarf plant habit, foliage that is green in color and flower buds that are yellow-green in color with no red coloration. ‘Baillagone’ can also be compared to the Lagerstroemia cultivar ‘Sarah's Favorite’ (not patented). ‘Sarah's Favorite’ is similar to ‘Baillagone’ in having clear white flowers. ‘Sarah's Favorite’ differs from ‘Baillagone’ in having a taller plant height and foliage that is green in color.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new ‘Baillagone’. The photographs were taken of a 4 year-old plant of ‘Baillagone’ as grown outdoors in full sun in Watkinsville, Ga.

The photograph in FIG. 1 provides a side view of ‘Baillagone’ in bloom.

The photograph in FIG. 2 provides a close-up view of the flowers of ‘Baillagone’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the Detailed Botanical Description accurately describe the colors of the new Lagerstroemia.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of 4 year-old plants of the new cultivar as grown outdoors in full sun in a trial garden in Watkinsville, Ga. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2015 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
