Survival of the Fittest

I went to Bow Point Nursery on the weekend. It's just west of the city. They focus on native plants, that don't require watering and that are hardy enough to survive the harsh Albertan climate (cold winters - hot summers).

I found the usual suspects - like lodgepole pine and sage.

I was rather surprised to see yucca, which are plentiful in California and Mexico - but Canada? According to BPN-Ken they grow naturally in Writing on Stone National Park in Southern Alberta and can deal with Calgary's weather just fine.
