great ted talk. I am good with the 6-8 Areca Palms, but if I put the other plants in my house I will have less room for my palm trees. not good. my studies indicate that overwintering any form of palm in your house is good for your attitude and well being. Of course I have no scientific proof with my study, it just makes me feel better when I see palm trees inside my house. 'nuff said.
