I don't know about the Thuja, but a Dwarf Alberta Spruce reversion to Picea
glauca isn't all that uncommon. It happened to one in my front yard a few
years ago (I cut it off), and there is one in a yard about a mile from me
that has had the reversion growing undisturbed for many years. The owner
just ignores it, and it is now quite a bit taller than the main plant; it
looks really bad.

Here is a link to a picture of a typical reversion:

Hi all,

I've been pondering mutations in conifers recently...I know really
exciting stuff. Anyway...

Secondly there is an Dwarf Alberta Spruce (Picea Glauca Conica IIRC)
near my house that has a differnt looking spruce growing right out of
the side. It looks non-drawf and fast growing. The needles resemble
it's parent in texture and density but the shoot growth and iternode
distance are considerably more coarse.
