Thanks for your response.

That sucks for me then that the pensylvanica isn't even semi-evergreen.

I'm going to have to do some deep digging looking for heterophylla and may experiment with 1 or 2 cerifera to see how it does.

Dzitmoidonc hit the nail on the head. With some BLEs in the north, the issue isn't strictly speaking one of hardiness, but how well it looks at the end of a typical winter. Plants that naturally go deciduous look better than evergreen ones that are burned by cold winds. That being said, its hardiness probably is borderline. Years ago I pulled a Myrica cerifera out of my garden - and this was in northern Virginia - because it was clearly struggling. Might have survived for years but never really looked good.
The Scott Arboretum doesn't list any M. cerifera.

Inkberry looks like a bayberry and is beautiful all winter long, you've probably seen it and thought it was bayberry. It doesn't have any real scent (its a native holly type, ilex glabra), but looks great.

You may have found this in your research but Northern Bayberry is dioecious so you will need a male and female if you intend on berries. I'm not sure if the Southern Bayberry is the same. This may be common knowledge but I found this out when researching this plant for our yard. I agree that the inkberry holly might be a better choice if you are set on an evergreen specimen.

I resigned to purchasing a few B&B northern bayberries (which are ubiquitous) but also a few southern bayberries in much smaller sizes and will wait patiently for them to grow.

Already have ilex glabras which are also very nice and much better than japanese hollies or boxwoods.

Cool, sounds like a good mix!

My cherry laurel remains evergreen. prefer it over the holly.

do you have pics of how you Bayberry hedge turned out?

Why not try one of the graceful Tsuga Canadenis varieties?
