Species azaleas are reproduced through seeds, but varieties do not reproduce true from a seed. They are propagated from stem cuttings creating a clone plant of the parent. All this selection in azalea plant types creates a variety of plant growing conditions, sizes, blossom colors and blooming times.
Many nurseries provide tags on their plants which will tell you the name and blooming period, as well as the eventual size of the plant and how cold hardy it is. Some have fragrant flowers (mainly Exbury Azaleas). All Azaleas are members of the Rhododendron family but not all Rhododendrons are Azaleas. They can be low growing, and never reach a height of more than two feet, but others can grow as tall twelve feet.
