Growing “Tahiti” Limes in the Home Landscape: https://edis.ifas.ufl.edu/publication/CH093
Tahita and Persian limes are in retail nurseries. These are cold sensitive so plant in protected areas. Key limes would need to be in a container for most people.
Rangpur lime is a lemon and mandarin cross.

Bananas continually produce nice foliage but do not form fruit in 5 years.  What to do?
Maybe not spend any more time trying to get fruit. If the bananas are in a large clump, you don’t want to have a large clump. Cut them back so that you have 3 bananas, one large, one medium, and one small so that you get lots of light. That is the key to fruit. Remove brown leaves.

Olives like a more consistent temperature than the Panhandle offers. Needs excellent drainage.

Mexican avocado has survived freeze and flooding but still not thriving. Why?
Avocado IPM: https://trec.ifas.ufl.edu/tropical-entomology/index.php
Hass avocado, smaller ones from CA and Mexico. South Florida is too warm to grow Hass but it may work in North Florida. Green skinned avocado is grown in South Florida. More tasty. Florida avocados need a little cool weather to initiate flower and then fruit.

Avocados will not like wet soils.

Will lychee and avocado grow in Pensacola?
Red fruit, white inside, similar to a grape but sweeter. Needs chill hours. 2018 lychee mite came into Florida and now in 13 counties. Difficult to manage.
