Shailesh: They're sooo easy to root. Just stick 'em in potting soil and keep it damp. In the winter they go dormant, even here in Hawaii. The leaves shed and the flowers fall. Bring 'em indoors to keep from freezing. Take 'em out when the frost warnings are pau.
Jenn: The sooner the better. It's becoming very "touristy" these last couple years, but there are still some hideaways that bring back the ol' days and ways. You just gotta have a good tour guide :)
I wish I could describe the smell of the flowers from under the trees...
