Feature Flower: Bird of Paradise

This was another arrangement for design school showcasing the fibonacci sequence played out in floral design.  It also used birds of paradise, so I thought I'd focus on them!  They're a tropical flower and, like most tropicals, long lasting. They are more expensive but you get size, durability, and long life. They lend a very structured and modern effect to arrangements.  (I used them in a wedding this summer that I still need to post pictures from.)  What do you think?  Do you like them?
