"Feijoa sellowiana O.

Myrtaceae

Common Names: Feijoa, Pineapple Guava, Guavasteen.
Related Species: In more recent times Feijoa sellowiana has been renamed Acca sellowiana, but most sources still use the older name.

Distant affinity: Eugenias (Eugenia spp.), Guavas (Psidium spp.), Jaboticaba (Myrciaria spp.).

Origin: The feijoa is native to extreme southern Brazil, northern Argentina, western Paraguay and Uruguay where it is common in the mountains.

Adaptation: Feijoas prefer cool winters and moderate summers (80� to 90� F), and are generally adapted to areas where temperatures stay above 15� F. Flower production is poor in areas with fewer than 50 hours of chilling. The flavor of the fruit is much better in cool than in warm regions. Even thought the plants are relatively hardy, sudden fall frosts can damage ripening fruit and late spring frosts can destroy blossoms. Spring frost damage is most likely in mild-winter areas, where the plants are not completely hardened off and respond to warm spells by blooming early."

Here is a link that might be useful: Feijoa

Thanks for the link but I've read that particular piece years ago. In fact I used to write for the CRFG as well as the Rare Fruit Council. I've also written about container growing tropical fruits for Horticulture magazine. Articles like this are general guidelines for growing and I'd like to hear from anyone with real time experience and who might have had success in growing the feijoa in Southwest Florida. Sometimes the seemingly impossible can be done as witnessed in Bill Whitman who fruited a mangosteen at his home in Bal Harbour Florida.
