Pieris Japonica
This is a Pieris Japonica I bought at the Jackson County Master Garden Fair in a one gallon container about 7 or 8 years ago. The new growth is always this stunning pink color. At first, when I saw it I thought it was a cross between a Pieris and an Azalea. ~ Jeanne Arago, AGC Member
