Henry's Red Rhododendron is covered in stunning clusters of lightly-scented ruby-red trumpet-shaped flowers at the ends of the branches in mid spring.
It has dark green foliage. The narrow leaves turn an outstanding purple in the fall. The fruit is not ornamentally significant. Henry's Red Rhododendron is an open multi-stemmed evergreen shrub with a more or less rounded form. Its relatively coarse texture can be used to stand it apart from other landscape plants with finer foliage. This is a relatively low maintenance shrub, and should only be pruned after flowering to avoid removing any of the current season's flowers. It has no significant negative characteristics.
Henry's Red Rhododendron is recommended for the following landscape applications. Henry's Red Rhododendron will grow to be about 5 feet tall at maturity, with a spread of 6 feet. It tends to be a little leggy, with a typical clearance of 1 foot from the ground, and is suitable for planting under power lines.
It grows at a slow rate, and under ideal conditions can be expected to live for 40 years or more. This shrub does best in full sun to partial shade. It requires an evenly moist well-drained soil for optimal growth, but will die in standing water. It is very fussy about its soil conditions and must have rich, acidic soils to ensure success, and is subject to chlorosis yellowing of the leaves in alkaline soils. It is somewhat tolerant of urban pollution, and will benefit from being planted in a relatively sheltered location.
Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This particular variety is an interspecific hybrid.

April Glow Rhododendron.It is the national flower of Nepalas well as, the state flower of Washington and West Virginia in United States, the provincial flower of Jiangxi in China and the state tree of Sikkim and Uttarakhand in India. Most species have brightly colored flowers which bloom from late winter through to early summer. Azaleas make up two subgenera of Rhododendron. They are distinguished from "true" rhododendrons by having only five anthers per flower.
They may be either evergreen or deciduous. In some species, the undersides of the leaves are covered with scales lepidote or hairs indumentum. Some of the best known species are noted for their many clusters of large flowers.
There are alpine species with small flowers and small leaves, and tropical species such as section Vireya that often grow as epiphytes. Species in this genus may be part of the heath complex in oak-heath forests in eastern North America. They have frequently been divided based on the presence or absence of scales on the abaxial lower leaf surface lepidote or elepidote.
These scales, unique to subgenus Rhododendronare modified hairs consisting of a polygonal scale attached by a stalk. Rhododendron is the largest genus in the family Ericaceaewith as many as 1, species,  though estimates vary from —  and is morphologically diverse.
Consequently, the taxonomy has been historically complex. At that time he considered the then known six species of Azalea  that he had described earlier in in his Systema Naturae as a separate genus. Linnaeus' six species of Azalea were Azalea indicaA. As new species of what are now considered Rhododendron were discovered, if they seemed to differ significantly from the type species they were assigned to separate genera.
Meanwhile, other botanists such as Salisbury  and Tate  began to question the distinction between Azalea and Rhododendronand finally inAzalea was incorporated into Rhododendron  and the genus divided into eight sections.
This structure largely survived till recentlyfollowing which the development of molecular phylogeny led to major re-examinations of traditional morphological classifications,   although other authors such as Candolle, who described six sections,  used slightly different numeration.
Soon, as more species became available in the nineteenth century so did a better understanding of the characteristics necessary for the major divisions. Maximovicz used flower bud position and its relationship with leaf buds to create eight "Sections".
The large number of species that were available by the early twentieth century prompted a new approach when Balfour introduced the concept of grouping species into series. The Species of Rhododendron  referred to this series concept as the Balfourian system. That system continued up to modern times in Davidian's four volume The Rhododendron Species. The next major attempt at classification was by Sleumer who from began incorporating the Balfourian series into the older hierarchical structure of subgenera and sections, according to the International Code of Botanical Nomenclatureculminating in with his "Ein System der Gattung Rhododendron L.
Sleumer based his system on the relationship of the flower buds to the leaf buds, habitat, flower structure, and whether the leaves were lepidote or non-lepidote. While Sleumer's work was widely accepted, many in the United States and the United Kingdom continued to use the simpler Balfourian system of the Edinburgh group.
Sleumer's system underwent many revisions by others, predominantly the Edinburgh group in their continuing Royal Botanic Garden Edinburgh notes. Cullen of the Edinburgh group, placing more emphasis on the lepidote characteristics of the leaves, united all of the lepidote species into subgenus Rhododendronincluding four of Sleumer's subgenera RhododendronPseudoazaleaPseudorhodorastrumRhodorastrum. A number of closely related genera had been included together with Rhododendron in a former tribe, Rhodoreae.
These have been progressively incorporated into Rhododendron. For a comparison of the Sleumer and Chamberlain schemata see Table 1 of Goetsch The era of molecular analysis rather than descriptive features can be dated to the work of Kurashige and Kron who used matK sequencing.
Later Gao et al. They confirmed that the genus Rhododendron was monophyleticwith subgenus Therorhodion in the basal positionconsistent with the matK studies. Following publication of the studies of Goetsch et al. Their work was more supportive of Sleumer's original system than the later modifications introduced by Chamberlain et al.Pruning techniques for developing azaleas
The major finding of Goetsch and colleagues was that all species examined except R. By contrast subgenera Azaleastrum and Pentanthera were polyphyleticwhile R. The small polyphyletic subgenera Pentanthera and Azaleastrum were divided between two clades.Rhododendrons are not difficult to grow in South Carolina where the soil and environment are suitable for their culture. Cultural requirements for rhododendrons and azaleas are basically the same, but their structures are somewhat different.
This publication will concentrate on the Southern native evergreen rhododendrons and hybrids. Rhododendrons come in many shapes and sizes, from the low-growing Carolina 5 to 6 feet tallto the large native rosebay 20 feet and more. Some varieties are rounded and compact while others have a loose growth habit.
The spectacular blossoms will appear anywhere from early spring to midsummer, with a color range much greater than that of roses — pure white through cream and yellow, apricot and salmon, the softest pinks to deep reds, lavender to deep purple and blue. Some have large trusses 12 inches across; others have blossoms that hang as individual bells.
There is wide variation in the shape and color of the leaves. Rhododendrons can be used in an open woodland setting under tall pines or oaks, in a small city garden, as a foundation planting for a suburban home or to landscape a large city building. They can be used as specimen plants, foundation plantings and hedges. Some rhododendrons can be espaliered trained to grow with the branches growing horizontally against a wall, fence or trellis or grown in movable tubs.
Oaks and pines are the most commonly mentioned companions for this beautiful shrub. They provide a high canopy of filtered shade while still providing the high degree of light intensity necessary for growth. The mulch provided by oak and pine trees breaks down and provides nutrients.
Rhododendron, bonitos, rústicos y muy resistentes
The soil should be kept aerated and the ground moist. For those not having these natural conditions, some additional help may be necessary. Rhododendrons have a few requirements: excellent drainage, a soil pH between 4. Site: Plant the rhododendron out of the wind and in dappled shade, preferably from a high cover of limbs that will give filtered shade all day. Some varieties will take a few hours of direct sun in the morning, but most need protection from the intense Southern sun.
Trees should be tall enough to be limbed up so the shrubs will get plenty of light. These trees will cut the force of drying winds in winter as well as summer.
Drainage is improved by planting on a slope — a northern slope is preferable to a southern slope. When using rhododendron in a foundation planting, avoid southern exposures. The best place to plant is on the north or east side of a building. Soil: The soil for these woodland plants must be well-drained and high in organic matter.
