Not a building perhaps, but architectural in its own way, this bull thistle growing from side of the Montessori school at 88 Main in Old Ottawa East is easily 7 feet tall. It's been a good June for that sort of thing and it's only half over.
Snapped this triffid-wannabe on my way back from a spin out to "old" Riverview Park in Alta Vista. Some amazing houses out there, especially the '53 vintage models on Knox Crescent. Will try to head back for some decent shots. The double-crescent section directly north of the old public school at 260 Knox is an object lesson on the suburban transition from side-gabled one-and-a-halfs to long-hipped bungalows, with lots of surprises in between. The subdivision was sold off as a collection of "builder's lots" rather than pre-builts so yeah, a box of chocolates for sure!
