Azalea plant named ‘Lazamorwhi’

Abstract

A new and distinct variety of Azalea plant, referred to by its cultivar name, ‘Lazamorwhi’, is disclosed. The new variety forms attractive, solid white-colored single inflorescences. Attractive medium-green colored foliage is formed, which contrasts beautifully with the flowers. A moderately vigorous, mounding, globose, upright growth habit is displayed. The new variety is well suited for providing attractive ornamentation in the landscape.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The accompanying photographs show as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant parts of the new variety. The plants of the new variety were grown in 3-gallon containers for approximately one year in an outdoor nursery in Cochranville, Pa.

(2) FIG. 1 illustrates a side view of the overall growth and flowering habit of the new variety.

(3) FIG. 2 illustrates a specimen of a flower—close-up view.

DETAILED BOTANICAL DESCRIPTION

(4) The chart used in the identification of the colors is that of The Royal Horticultural Society (The R.H.S. Colour Chart, 2015 edition), London, England. The terminology which precedes reference to the chart has been added to indicate the corresponding color in more common terms. The description is based on the observation of specimens of the new variety during July 2021 under natural light conditions in Cochranville, Pa. Measurements and numerical values represent averages of typical plants. Botanical classification: Rhododendron hybrid cultivar Lazamorwhi. Commercial classification: Azalea Plant.
