Kirk,
I don't know of any gardens with a CP collection, but
I could give you a list of places to check:
Queen Elizabeth Park Conservatory
The conservatory is located at the top of the hill in the park.
Its been a few years since I was there. They have a tropical
environment inside.
Stanley Park Zoo Aquarium
The zoo area has been renovated a few years ago.
The aquarium is supposed to have an interesting rain forest exhibit.
UBC Botanical Gardens
I really don't think they have a CP collection.
I was there last summer and found that the garden is essentially all
outdoors.
6804 SW Marine Drive
822-9666 Garden
822-4801 Nursery
"UBC Greenhouse" ???
I call this place "UBC Greehouse" because I am not sure what the place
is called or where it is located.
I went there on a field trip in elementary school. :-)
They showed us a tropical plant that would close its leaves to avoid
damage from heavy rainfall.
I think they might have a CP collection there.
You might be able to find out about this place by calling the Botanical
Gardens.
I wish I could be of more help. Let me know if you find anything.
BTW, there should be decent skiing in the local mountains if you are
interested. There was some new snow Monday night.
