Rhododendron x ‘Hino-crimson’ (Kurume Hybrid) – One of the most popular Japanese azaleas and for good reason. It bears hundreds of small single, bright crimson flowers that literally smother the foliage from April to May. This Award of Garden Merit winner has tiny deep green leaves that turn bronze-red in winter. ‘Hino-crimson’ grows 2-3′ high by 3′ wide. Zone 6.
Rhododendron x ‘Ben Morrison’ (Morrison Hybrid) – An absolutely spectacular Japanese azalea with large (2″ wide) bi-color blooms of intense salmon-pink that fade to generous white edges and are accented by rose-purple spotting in the throat. This 1972 introduction does grow higher than most, reaching heights of 5′ tall by 3-4′ wide. Zone 6.
Rhododendron x ‘Hino-white Dwarf” (Kurume Hybrid) – A truly spectacular evergreen azalea with innumerable pure white ruffled blooms that cover the entire plant contour from April to May. This cultivar is much denser than ‘Hino-white’ and can be easily sheared (after blooming) into an informal flowering hedge. Grows 2 to 2.5 feet tall and wide. Zone 6.
Rhododendron x ‘Girard’s Fuchsia’ (Girard Hybrid) – Eye-catching ruffled flowers (2.5 to 3″ wide) of a deep fuchsia-pink (with dark pink spots) often cover the bright green foliage from April to May. The leaves turn a bronze-red in fall when exposed to colder temperatures. ‘Girard’s Fuchsia’ prefers part to full sun and grows 3-4′ high and wide. Zone 5.
Rhododendron x ‘Variegata’ (syn. Azalea ‘Silver Sword’) (Girard Hybrid) – This sport of ‘Girard’s Rose’ was discovered in 1975 and features mid-green foliage with prominent creamy-white margins. The large pink blooms (2.5″ wide) emerge from darker buds and are borne from April to May. The leaves brown when exposed to cold winter winds. Grows 3′ tall and 4′ wide. Zone 6.
