A greenhouse, I recently experienced, is both a physical and psychological oasis in the dead of winter.

Plants are proven mood enhancers and the heritage greenhouse here in Ottawa houses more than 500 lush tropical varieties.

The building itself is a sight to behold. It's a soaring web-like structure made almost entirely of glass and metal, a seemingly too thin separation from the realities of a harsh winter day. Yet inside you're guaranteed the air is warm and humid. You can ditch your winter duds, close your eyes and be momentarily transported to somewhere tropical.

Here's hoping there's a greenhouse somewhere near you.
