Good to know.. Have papaya trees and coconut trees behind the house here in south florida USA.. It seems i am the only one around who picks and eats them... They plant them ornamentally but i know good health food when i see it... Will have to try papaya leaf soon and not wait for dengue as an excuse...Thai food uses green papaya a lot...
I grew several papaya from fruit I bought at the market here in West Central Florida. They did well for about 18 months then succumbed to termites that are prevalent in this area. :(
