Cool contest! I love green too. :) Here's a photo with only green in it:

I shot this in the tropical Spice Garden of Penang, Malaysia. It's called Sweet Prayer Plant, native to western part of Africa, and is now also commonly seen in tropical Asia. Its large papery green leaves are popular for decoration purpose, as well as for wrapping and boiling food. Local people also use them as weaving materials, building materials, and for roofing. Plus it’s a natural source of thaumatin, a low-calorie sweetener and flavor modifier protein. Its leaf sap can also be used as sedative and as antidote against venoms, stings, and bites.

Btw, I'm hosting a Cross-culture Challenge, feel free to join Petr. You and Lil must have a lot to share about this topic! =)
