They range in size from a few inches tall to giants
reaching 80 feet in the air. There are both deciduous
and evergreen rhododendrons. Most commonly, their
flowers are in shades of white, pink, red,
lavender, or purple and various bicolor types.
A point of confusion often arises over the term
"azalea". The key to remember is that all
part of the genus, Rhododendron.
Again, there are both deciduous and
evergreen plants in both category of
debate over what exactly differentiates an azalea from a
rhododendron. Some look at the number of anthers in the
flowers but I use a simpler classification system. To me,
azaleas are just rhododendrons that bear their flowers all along
the stems while rhododendrons produce their blossoms at
the terminal end of branches.
Members of this genus tend to have exacting
requirements in terms of site, soil and climate.
