Abstract

A new and distinct variety of Azalea found as a mutant sport of Azalea ‘Conleo’. The new variety possesses a unique blooming time and is superior in development. An upright, dense, globose shaped plant with attractive, ruffled, large semi-double white flowers.

Description

Latin name: Rhododendron hybrid ‘Mootum’.
Variety denomination: ‘Mootum’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct variety of evergreen azalea of the genus Rhododendron and a member of the Ericaceae family. This new azalea variety, hereinafter referred to as ‘Mootum’, was discovered by James Bryan Berry in 2001 in Loxley, Ala. ‘Mootum’ was discovered as a naturally occurring sport mutation of the Azalea plant named ‘Conleo’, U.S. Plant Pat. No. 11,640. The value of this new cultivar lies in its unique blooming period, bloom color, bloom form, bloom size, and growth habit.
Asexual propagation of the new plant by cuttings has been under Mr. Berry's direction in Loxley, Ala. Several generations of the new plant have been evaluated and the distinctive characteristics of the plant have remained stable. The plant cannot be reproduced true from seed.
BRIEF DESCRIPTION OF ILLUSTRATION
This new Azalea Hybrid variety is illustrated by the accompanying photographic prints in which:
1. FIG. 1 is a close-up showing flower and foliage of the new cultivar ‘Mootum’.
The colors shown are as true as is reasonably possible to obtain by conventional photographic procedures. The colors of the various plant parts are defined with reference to The Royal Horticultural Society Colour Chart (R.H.S.C.C.). Description of colors in ordinary terms are presented where appropriate for clarity in meaning. Colors in the photographs may appear different than actual colors due to light reflectance. Color values cited in the Botanical Description of the Plant accurately describe the actual colors of the new Azalea.
DETAILED BOTANICAL DESCRIPTION OF THE PLANT
The following is a detailed description of the new variety of Azalea based on my observations made of plants grown in wholesale commercial production practices, in greenhouses, and in established landscape plantings in Loxley, Ala.

  • Classification:
      • Botanic.—Rhododendron hybrid ‘Mootum’.
      • Form.—Upright, dense, and rounded.
      • Height.—5′.
      • Width.—4′.
      • Growth habit.—Upright, dense and globose. Fast growth rate under normal fertilization and moisture conditions.
      • Growth rate.—In a period of six years from a rooted cutting the plant reaches a height of 3 feet and a spread of 4 feet. The growth rate is normally about 10 to 12″ per year; the plant reaches an approximate height of 5′ at maturity while maintaining a dense habit due to the abundant branch development.
      • Foliage.—Alternate, simple, evergreen, pubescent, elliptic, and varying in size from 1½″ to 1⅞″ long and ⅝″ to 13/16″ wide. The margins are entire, with a petiole 3/16″ to 5/16″ long. Midveins and laterals are impressed on the upper leaf surface and prominent on the underside. The base of the leaf is cuneate to attenuate and the apex is acute to mucronate. The upper surface of the immature leaves are dull, pubescent, and are RHSCC Yellow-Green Group 144A and the underside is RHSCC Yellow-Green Group 146D, pubescent, and the matte. The upper surface of the mature leaves are RHSCC Yellow-Green Group 146A, dull and slightly pubescent and the underside is RHSCC Yellow-Green Group 146C, matte, and pubescent. The immature petioles, midribs and veins are RHSCC Yellow-Green Group 146C. New growth is pubescent. These hairs are initially soft and white and cover both sides of the leaf with a higher concentration on the petioles and veins. They are slightly curled, flat, and range in length from 1/32″ to ⅛″. As the growth matures much of the leaf pubescence is lost; however, the stems, petioles, and leaf veins retain this pubescence which becomes more setaceous and darker in color (RHSCC Brown Group 200A) through the growing season.
In 2005, the date of initial spring growth was March 15, in Loxley, Ala. After the initial spring flush there was almost continuous growth until that fall ending October 20, also in Loxley, Ala. When grown in full sun, the internode length of this plant is 3/16″ to ½″; when grown in light shade the internode length is ⅜″ to ⅝″. As would be expected a plant grown in shade results in a taller, less dense plant with larger leaves.
The average length of terminal growth of the initial spring flush is about 6″ for a plant in full sun and about 8″ when grown in shade. This growth should not be trimmed since it will produce flowers starting in mid July. As the plant continues to grow through the summer and fall more flower buds are produced, which mature and bloom until frost. This remaining growth produces about 5″ to 6″ of height. As cool weather approaches, some of the flower buds become dormant. These buds bloom in April of the next year.
      • Stems.—The young stems are RHSCC Yellow-Green Group 146C and densely clothed with spreading white glandular hairs. During the second growing season they become RHSCC Greyed-Green Group 197B, glabrous and rugose. The pith is solid and uniform. Young and older stems are densely branched. The mature stem is RHSCC Grey-Brown Group 199A in color.
      • Buds.—Tight buds at ½″ are ovate and acuminate RHSCC Yellow-Green Group 146D with a hairy pubescence Brown Group 200A. The buds are borne in clusters of 2 to 4, and are sheathed by a pair of modified leaf bracts which are from ¼″ to ½″ long, persistent, and RHSCC Yellow-Green Group 147A. The pedicel is ⅜″ to ½″ long, pubescent, and RHSCC Red Group 53C. The calyx is ⅛″ to ¼″ long, RHSCC Yellow-Green Group 144B, funnel shaped, persistent, and pubescent. The five imbricated sepals are lanceolate and joined at the base to form a cup. As the buds swell the bud sheath matures to a RHSCC Greyed-Orange Group 165A, falls off, and reveals the flower color RHSCC White Group 155D.
      • Flowers.—Perfect, semi-double, upper surface of throat and flecking is RHSCC Yellow Group 4D Upper Surface petal color is RHSCC White Group 155D Lower surface petal is RHSCC White Group 155C. Petals are 1¼″ long and 9/16″ wide. Each petal has a stripe from throat to tip (one stripe per flower) that is RHSCC Red/Purple Group 62D. Glabrous, openly funnel shaped flowers are 2½″ to 3″ wide by 2″ to 2¼″ long, borne on current season's growth, non-fragrant; they last on the plant in the garden 5 to 6 days. There are five true petals which are fused at the base, elliptic to obovate, and have wavy margins. There are 0 to 5 non-petaloid stamen which are ¼″ to 1″ long. The filaments and the anthers are both colored RHSCC Yellow Green Group 145D and the pollen matures to RHSCC Yellow Group 11B. The 5 to 10 petaloid stamen are from ¾″ to 2″ long and odd shaped. The petaloid stamen's color is RHSCC White Group 155C. The uppermost petaloid stamen are dotted. The dots are colored RHSCC White Group 155B. The pistil is single, non-petaloid, ¾″ to 1½″ long and the ovary is densely glandular-setose and has five locules. The pubescent peduncle is 5 mm long and it's color is RHSCC Yellow-Green Group 149C. Fruit was not observed. There is a 2 to 3 week flowering period in April in Loxley, Ala. Flowering resumes in mid July as the new buds mature and continues until frost which can be as late as November or December in Loxley, Ala. Azaleas blooming at this time of year attract butterflies in profusion.
      • Culture.—Grows well in a wide range of conditions, tolerates sun to shade. Prefers a moist, well-drained soil that is rich in organic matter. Responds well to mulching and medium applications of fertilizer; prefers ph 5.0 to 5.5. Very little pruning is needed; adaptable to container and above ground planters; makes a good foundation plant or informal hedge with excellent foliage and flower contrast. Ideal for coastal regions and warmer parts of Piedmont. Propagated with semi-hardwood cuttings in late spring through the summer.
  • Pests: Lace wing and spider mites can be a problem.
