|Album Elegans, like Album, bears white flowers, but it is not quite so cold-hardy as Album. VIgorous, shrubby, evergreen "ironclad" rhododendron with medium leaves. Flowers bloom in late midseason. Tolerates sun and wind.
There are between 500 and 900 species of evergreen and deciduous plants in the Rhododendron genus. Azaleas fall into this category. The evergreen rhododendron is characterized by medium to long, elliptical leaves and large, clustered, trusses of, late, showy, spring to early summer flowers, ranging in colors from red, pink, white, lavenders, purples and even yellow and orange. Form maybe low and mounding to gangly and almost tree-like with age. All rhododendron love well-drained, acid soil and should be planted high, preferably on raised beds. Partial shade is preferable too, though many plants grown quite well in full sun in cooler, more forgiving climates. In general, the evergreen rhododendron tends to do better in cooler areas of zone 7 and lower, thriving in the Appalachian Mountains and the Pacific Northwest. Rhododendrons, as a genus, are divided into 5 groups: large-leaf evergreens (elepidotes) - the ironclad hybrids (hybrids between R. catawbiense, R. ponticum, R. caucasicum), Fortunei hybrids (tall and bushy, large flowers), Yakushimanum hybrids (low and compact) small-leaf evergreens (lepidote) - Hardy, low-growers include R. dauricum and R. minus Vireya rhododendrons - Also known as Malasian rhododendrons; often epiphytic and tender; best in greenhousedeciduous azaleas - some native, some hybridized, Knapp Hill and Mollis most popular evergreen azaleas- the azalea group
