Hi Mike!
I am a little worried about the Osmanthus hedge. Osmanthus fragrans ultimately get large, even can be small trees, and it may be too close to the sidewalk. Osmanthus fragrans blooms on old wood (formed the prior year)so if you plan to prune it to keep it in bounds you may end up keeping it from blooming, and it may require pruning 3-4 times a year to keep the sidewalk clear. It is also possible that this particular cultivar blooms on new wood, I am no expert.
I have found that the plant tags on new cultivars of shrubs are often WAY underestimating the ultimate size, and I have been really sorry I believed the hype. I can't tell you how many shrubs I have had to get rid of because I planted them according to the labeled size. That said, I have not really lived with or seen Osmanthus hedges, they are rare around here. Have you seen successful hedges of it?
BTW- I LOVE the Osmanthus Fragrans 'Fudingzhu', I got the 'Apricot Echo' from Logees Greenhouse for my sister this spring, it struggled in a 6" pot in my window and was planted in August. Now it is 2 feet tall already and blooming!
