Thuja o. (I assume?) is happy in a wide variety of soils and conditions. I've found them growing on the sides of hills in sand and gravel and have actually witnessed them growing on a floating island in a northern Michigan lake, complete with loon's nest (on island). My neighbor and I went Dutch on costs & planting efforts to establish a hedge of about 40 trees between us about 12 years ago. The trees are about 18 ft tall now and growing well. We planted them 4 ft apart. They grew together and tall enough to offer privacy by the 6th year. I've had to tie a couple of stems up after snow weighed them down, but there has been no die-off or other problems so far. I am pleased with the results and the appearance.

They don't appreciate salt in any form. Salt spray from roads or run-off from roads, sidewalks, or drives will leave the trees with dead or burned foliage and you disappointed.

I have a shade garden adjacent to the Thujas because of how they are sited in relation to my garage, which gives afternoon shade. How well your list of plants will do will depend mostly on whether they are on a sunny exposure or shaded.

Thanks, Al. Sorry this response is a little late. I can't wait to plant them.
