Azalea plant named ‘Lazamoropi’

Abstract

A new and distinct cultivar of Azalea plant named ‘Lazamoropi’, characterized by its medium purple-colored flowers, dark green-colored foliage, moderately vigorous, semi-upright growth habit, and strong multi-seasonal reblooming, is disclosed.

Description

Latin name of genus and species of plant claimed: Rhododendron hybrid.

Variety denomination: ‘Lazamoropi’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Azalea plant botanically known as Rhododendron hybrid and hereinafter referred to by the cultivar name ‘Lazamoropi’.

The new cultivar originated in a controlled breeding program in Independence, La. during the spring of 1996. The objective of the breeding program was the development of Azalea cultivars with attractive flower color with multi-seasonal blooming and that perform well in the garden.

The new Azalea cultivar is the result of open-pollination. The female (seed) parent of the new cultivar is the proprietary breeding selection coded VFXOHI-1, not patented, characterized by its medium fuchsia-colored flowers, dark green-colored foliage, and vigorous, upright growth habit. The male (pollen) parent of the new cultivar is unknown however the female was outdoors and in close proximity to numerous proprietary hybrids that had cold hardiness, compact growth habit, and multi-seasonal blooming traits. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated open-pollination during the fall of 2010 in a controlled environment in Independence, La.

Asexual reproduction of the new cultivar by terminal stem cuttings since the fall of 2010 in Independence, La. and later in Loxley, Ala. and Irvington, Ala. has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Lazamoropi’ as a new and distinct cultivar of Azalea plant:

• • 1. Medium purple-colored flowers;
  • 2. Dark green-colored foliage;
  • 3. Moderately vigorous, semi-upright growth habit; and
  • 4. Strong multi-seasonal reblooming.

Plants of the new cultivar differ from plants of the female parent primarily in having reduced growth vigor, and a different growth habit.

Of the many commercially available Azalea cultivars, the most similar in comparison to the new cultivar is Autumn Royalty ‘Conlec’, U.S. Plant Pat. No. 10,580. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Conlec’ in at least the following characteristics:

• • 1. Plants of the new cultivar have a flower color that is a shade of purple different from plants of ‘Conlec’;
  • 2. Plants of the new cultivar are more compact than plants of ‘Conlec’; and
  • 3. Plants of the new cultivar have a leaf color different from plants of ‘Conlec’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs may differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Lazamoropi’. The plants were grown in 2-gallon containers for 9 months outdoors in Irvington, Ala. Plants were given one pinch at transplant.

FIG. 2 illustrates a close-up view of an individual flower of ‘Lazamoropi’.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2007 edition, except where general color terms of ordinary significance are used. The color values were determined in March 2015 under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe plants produced from semi-hardwood stem cuttings from stock plants. Rooted plants, liners, were transplanted into 2-gallon containers utilizing a soilless growth medium. Plants were given one pinch at transplant and grown for approximately 9 months outside in Irvington, Ala. under conditions comparable to those used in commercial practice. Average winter temperatures ranged from 63° F. to 42° F. (17° C. to 5° C.) and average summer temperatures ranged from 91° F. to 72° F. (33° C. to 22° C.). Measurements and numerical values represent averages of typical plants.
