Myth buster proved this BC myth correct
Whispers in eastern Canada about palms and bamboo along the British Columbia coast were words of taboo. Nowadays exotic flora in coastal BC can be enjoyed by the entire country. The author of this channel names plants while he displays them on his channel. It's great for the BC coastal gardener.
The wonders of BC contradict Canadian gardening as a whole. Think of Hong Kong as being a different part of China. Now think of BC as a SAR zone but for gardening rather than politics. Every Canadian gardener should experience BC gardening with at least a visit.
