I would like to plant a pieris japonica shrub at the northeast corner of my house, but I'm having trouble deciding what variety. There are 4 varieties that I can get locally: Mountain Fire, Pink Flamingo, Flaming Silver, and Red Head. I'd like something that will be about 6 feet tall, but every website I visit gives conflicting information regarding mature height. Does anyone have any of these varieties that can speak from personal experience? Or perhaps there is a particular website that you trust as being more reliable?

FYI, my soil is moist but well-drained, slightly acidic. My house has a brick foundation and so should not cause any issues with concrete leaching. There is, however, a nearby concrete sidewalk, though it has been in place for at least 30 years. This spot gets morning sun - about 8 am until about one - and afternoon shade.
