It is a lovely spot in a gorgeous part of Canada. I am originally from Vancouver, but had never heard of it until I visited my brother who lives near Parksville now.
I think if you can grow dahlias, you can grow that chocolate cosmos. Just my opinion, but I don't think it's really a cosmos at all.
They really do smell like chocolate, though.
Couple more of the garden tour - real cosmos, hydrangeas do very well there, and they made the old swimming pool into a water garden, but the water lilies were just barely getting started. It will be gorgeous in future years.
