I've also wanted to grow pomegranates in FL, but all I've found are sad answers. I've yet to see a review that the tropical pomegranates are worth eating, and the state is too humid to grow temperate pomegranates without spraying for fungus several times a year. Even if you were willing to spray temperate poms they still might not work out for you in Wellington because they do need some chill hours (~200?).
I contacted Green Sea Farms before they shut down (they were running a huge pom variety trial for UF) to ask about what varieties resisted humidity & diseases the best, and they recommended Christina and Vories varieties. I have in my notes that UF says that Christina is popular as a home garden cultivar and is reliable in the humid south. It originates in North Florida and that it has a mild taste with pale, almost clear, arils. It did 'fair' in taste tests. Vories originates in Gainesville, FL, has a 'sweet flavor' and has a light yellow or colorless arils.
Parfianka has great fruit, but it would need to be sprayed else a fungus will rot the fruit. The disease looks a lot like blossom end rot.
