Did you know - there are male and female hala trees. The females grow strange-looking fruit (technically edible, but I'm told not great-tasting). The males are quite rare and have beautiful fragrant flowers that can be used in stunning flower arrangements.
Hala trees played a very important role in Hawaiian history - many parts of these trees were used for everything from food to medicine, home building to leis. Do take a moment to google 'hala trees' for some interesting reads (I liked this
Native Plants Hawaii website). By the way, a hala lei can be very lucky or very unlucky... you may want to look into that before asking where to find one!
