I was just admiring our specimen of the East Coast native, Thuja occidentalis ‘Concessarini’ today. I find this a fascinating plant in the garden, sadly never promoted by those who claim to extoll the virtues of native plants.
Our oldest specimen below is now 10 years old and measures 3′ tall x 6′ wide…quite a bit larger than it’s introducer claims it to be at 1′ tall x 2′ wide. If you dig deeper, you’ll see that the plant patent application shows they only measured a three year old plant, and have never bothered to update the mature size in their marketing or on their tags. It shows how little many plant introducers think of the end consumer, when they set them up for failure by promoting these fake mature sizes. Commercially, it is marketed under the fake trade name of Pancake arborvitae. That’s one seriously lumpy pancake.
This juvenile-foliage sport of Thuja ‘Linesville’ was discovered by nurseryman, Gabriel Cessarini. We think it’s pretty cool, just allow enough room in the garden. Winter hardiness is Zone 3a-8b.
