Scotland has a beautiful flowering shrub that grows like weeds along their roadsides. I was told it was called a 'pieris'. I believe Scotland is a zone 7. I live in 5b. I was told that the shrub would grow for me as long as it was sheltered from the winds. We purchased and planted a shrub three years ago. Technically it is still alive, gets leaves each spring and sort of flowers but it has not grown at all. Can anyone tell me exactly how to look after this plant? ~ Thanks.
