Definitions
- Genus species Rhododendron hybrid.
- 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 ‘Robled’, was discovered by Robert Edward Lee in July, 1995 in Independence, La. ‘Robled’ originated as a naturally occurring branch sport of Azalea hybrid ‘Conled’ U.S. Plant Pat. No. 10,568 while it was being grown in Independence, La. The value of this new cultivar lies in its unique blooming period, bloom color, bloom form, bloom size, and growth habit.
- the photograph at the top of the sheet is a close-up showing flower, foliage, and stem color as well as flower size and form.
- the photograph at the bottom of the sheet shows the dense and globose growth habit of a young three gallon plant.
- ‘Robled’ originated as a branch sport of Azalea hybrid ‘Conled’ U.S. Plant Pat. No. 10,568 which was the result of Mr. Lee's planned cross hybridization between the Azalea ‘White Gumpo’ and Rhododendron oldhamii ‘Fourth of July’.
- the new variety differs from ‘Conled’ in its flower color which is White Group 155D to Red Group 56C rather than Red Group 48B.
- Mr. Lee's hybridization program was conducted with emphasis on species that are not commonly found in the genetic make-up of the present day hybrids.
- the ‘Fourth of July’ cultivar is a heavy summer and fall blooming plant, not like the Rhododendron Species Foundation form.
- Mr. Lee used this cultivar to cross with existing hybrids which have a tendency to bloom in the fall and which are also fairly hardy. As expected, the resulting seedlings are heavy summer and fall bloomers with very impressive spring blooms also.
- the average length of terminal growth of the initial spring flush is about 4′′ for a plant in full sun and about 6′′ when grown in shade. This growth should not be trimmed since it will produce flowers starting in early 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 4′′ to 5′′ of height. As cool weather approaches, some of the flower buds become dormant. These buds bloom in April of the next year.

- Classification:
- Botanical: Rhododendron hybrid ‘Robled’.
- Form: Low, dense, and rounded.
- Height: 3-4′.
- Width: 4-5′.
- Growth habit: Low, 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 2 feet and a spread of 3 feet. The growth rate is normally about 6 to 8″ per year; the plant reaches a height of 3 to 4′ 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 1¾″ long and ½″ to {fraction (5/18)}″ wide. The margins are entire, with a petiole {fraction (3/16)}″ to {fraction (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 is dull, pubescent, and is Yellow-Green Group 144A and the underside is Yellow-Green Group 146D, pubescent, and matte. The upper surface of the mature leaves is Yellow-Green Group 147A, dull and slightly pubescent and the underside is Yellow-Green Group 146B, matte, and pubescent. The immature petioles, midribs, and veins are 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 {fraction (1/32)}″ to {fraction (3/32)}″. 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 (Brown Group 200B) through the growing season.
- Stems: The young stems are Yellow-Green Group 146C and densely clothed with spreading white glandular hairs. During the second growing season they become Greyed-Green Group 197B, glabrous and rugose. The pith is solid and uniform. Young and older stems are densely branched.
- Buds: Tight buds at ½″ are ovate and acuminate Yellow-Green Group 146D with a hairy pubescence Brown Group 200A. The buds are borne in clusters of 3 to 4, and are sheathed by a pair of modified leaf bracts which are from ¼″ to ½″ long, persistent, and Yellow-Green Group 147A. The pedicel is ⅜″ to ½″ long, pubescent, and Red Group 48A. The calyx is {fraction (3/16)}″ to ¼″ long, 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 Greyed-Orange Group 165A, falls off, and reveals the flower color White Group 155D to Red Group 56C.
- Flowers: Perfect, single, glabrous, open funnel shaped, 2½″ to 3″ in diameter by 2¼″ to 3″ in depth, borne on current season's growth, non-fragrant; they last on the plant in the garden 5 to 6 days. Flower color is mostly White Group 155D with occasional flowers being partially or wholly Red Group 56D. These color designations are for both the upper surface and the undersurface. A plant with these color variations is not fixed except in the sense that it will continue to produce a known range of variants. There are five petals which are fused at the base, elliptic to obovate, and have wavy margins. These petals are 1¾″ to 2¼″ long, ¾″ to 1¼″ wide, and have rounded apexes and entire margins. Three out of five petals are dotted with Red-Purple Group 71C. There are 5 to 9 stamens which are 1¼″ to 1¾″ long. The filaments are Red-Purple Group 56B, the anthers are Red Group 44A, and the pollen matures to Yellow Group 11B. The pistil is single, 1¾″ to 2¼″ long and Red Group 51A. The ovary is densely glandular-setose and has five locules. The capsule matures in about 5 months, in Independence, La., to about ¼″ to ½″ long; it has a persistent style, is Yellow-Green Group 147A, and contains from 100 to 400 nonwinged seeds. Normally fruit set is not heavy. There is a 2 to 3 week flowering period in April in Independence, La. Flowering resumes in early July as the new buds mature and continues until frost which can be as late as November or December in Independence, La. 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.
