Potential sources for them would also be appreciated. The weirder and more niche, the better. Edit: I’m in hardiness zone 13b
Some stuff I already have: Basil Mint Tomatoes Sage Lemongrass Marjoram Coleus caninus Cuban Oregano Passion Fruit Pumpkin Honeydew Avocado Cashew Coconut
Rub a leaf between your fingers. The smell can tell you sometimes which fruit you'll get. Other than that you need to wait to find out.
In terms of citrus I can recommend satsumas, my 2y old tree gave me about 40 fruits this year alone and they taste great.
Satsumas look really cool. I love mandarin oranges. Any specific suppliers you recommend?
