You can always go to you local supermarket too. I know that here in North America they usually have a little flower center, and it's a treat, in the middle of winter, to spend a bit of time among the green. Right now, our supermarket has orchids on sale for $15. I'd love to get one, but I already have 4 orchids, none of which are in bloom right now.
Yes, I really enjoy that philodendron, but it takes up a whole corner of my living room!
