My azaleas are over 30 years old and are beginning to show it. Some have died off and have
been replaced. I have two kinds: Herbert has a 'single' flower and blooms first, and Karen has a
'double' flower and blooms several weeks later.
Below is Herbert with a 'single' bloom (one row of petals).
Below is Karen with a 'double 'row of petals. This is called hose in hose.
