What is the selection like at the indoor plant sale? I'm going to be in the Vancouver area around that time and thought it would be a good chance to visit the garden, (haven't been before) and maybe find some neat plants. The website has a general list, but I was wondering if there will be rare plants there? What kind of succulents can I expect? Has there been any caudiciforms at the sale in the past? Would this be a great way to find plants that I can't seem to find anywhere else? Thanks.
