I have actually heard that there are some more exotic palms in Oak Bay. I cant remember their names though.
The coldest temperature ever recorded in Oak Bay was -11 in February, 1986.
Their coldest month is january with an average high of 7.2 and low of 3.7.
And here is the amazing part.
On average only 10.3 days a year fall below freezing with only 3.7 days a year recording a low below -2!
So there are many, many plants that in Canada, you can only grow in oak Bay and some of the other extremely mild sections of the Gulf Islands / southern Vancouver Island.
