Swamp Azalea Deserves More Garden Space

              Swamp Azalea (Rhododendron viscosum, formerly R. serrulatum) is very different among deciduous azaleas. Most rhododendrons (azaleas) do not care for soppy, poorly drained soils.

Winter Damage On Crape Myrtles

                Extremely cold winters of 2013-14 and 2014-15 have damaged many cultivars of crape myrtles (Lagerstroemia x indica).
