Dave,

Thuja orientalis is actually correct. I think a lot of us here got off on the wrong path (after) we used to call it Thuja to begin with.

(Jacobson 'North American Landscape Trees')

"Introduced to Europe ca. 1700. Named in 1753." What the 'ca.' means I have no idea.

The species was first described as Thuja orientalis, but it was later shown that it is only distantly related to the other species of Thuja, so was separated into a genus of its own Platycladus, of which it is the sole species. When the species is moved to a new genus, it of course takes all its cultivars with it.

Note the very different cones; left to right, Platycladus orientalis, Thuja occidentalis, Thuja plicata, Thuja standishii.

PS Dax - 'ca.' means 'circa', "about" (they don't know the exact date of introduction)

That makes sense. Cones, cones, cones..

Thanks for the 'ca' too!

Dax

Its also important where you put the dot: while 'ca.' means 'circa', '.ca' means Canadian internet domain :O)

i dont understand resin's answer ... is it thuja or not???

your picture.. looks EXACTLY like the plant i moved to a new location yesterday .... cool... ken

Hi Ken,

It used to be listed as Thuja, but it isn't any more now (except for a few stick-in-the-mud nurserymen who don't want to get themselves up-to-date!)

hi michael ...

i swear i changed my database .. because you told me the opposite a few years back ...
