@MariposaMaid, I have a bit of an aversion to planting brambles/thorns. I've been hunting for an evergreen Rubus that's thornless, though I haven't been successful. If there was one with thorns that was incredibly tasty and produced well, I'd consider it, but the ones I've found are more ornamental. As for Pineapple Guava, I've seen that it's evergreen and hardy in zone 7, but with the cold the fruits are unlikely to develop.

for the link! I'll cross research it later to see if any of them are desirable eating.
