Which Thuja Plicata to plant?

Posted by shutton none (My Page) on

I need to plant some tree/shrubs for a privacy wall that will be about 60' long. I have about 8 feet between a split rail fence and the road. Also I live in New Jersey if that matters. I have been recommended Thuja Plicata 'Excelsa' but then someone else recommended Thuja Plicata 'green giant'. When I questioned they came back with Thuja Occidentalis Elegantissima. Can anyone shed some light on which plant may be best for me or the differences between them?

1. none of these are shrubs :-)
2. Only the first listed is a true T. plicata - 'Green Giant' is a hybrid and 'Elegantissima' is a pyramidal form of American arborvitae.
3. All are going to offer slightly different matrure heights, widths and growth rates.

If 8' is the maximum spread, both 'Excelsa' and 'Green Giant' will get wider, although not very rapidly. And they can be pruned/sheared to maintain more of a hedge-like narrow appearance.

The Green Giants will offer the fastest growth at 3+ feet per year, growing conditions being similar and proper to the plants' liking.

3' per year it has been acknowledged on this site was based on plants inside greenhouses. As I remember it the National Arboretum page on this introduction (made by them) says 1' per year. Splitting the difference is probably about right, at least for young and vigorous stock. Plants I have seen on the market here did not look to be progressing particularly rapidly, as far as it goes.

All three are tall-growing conifers reaching definite tree height, even 'Elegantissma' which is unusually coarse and vigorous for an eastern arborvitae. It was mistaken for a form of western redcedar in Vancouver, BC plantings by G. Straley in his Vancouver tree book.
