My wife loves fruit. We have a mature mango tree, watermelon vines, star fruit trees, papaya and dragon fruit in the yard.

My wife is from the Philippines. She grew these in her back yard in soCal the only person I know who did. She took them to work and the others gulped them up. Don’t know where you are but this might be a nice addition.
