Lore, I live a half hour from Smith and often go to the greenhouse. Maybe we could meet there next time you are here! I also got my BA from UMass. I have been to Kew years ago now, but loved it. I'm hoping to have time to go to the Brooklyn Botanical Gardens this weekend while in NYC. I spend most of my computer time on my crazy orchid lady website but I check in here periodically. You can send me a tree mail.
