Pineapple Guava. Whats cool about this plant is that the flower pedals are edible, and taste like cotton candy. Latin: : Feijoa sellowiana syn. Acca sellowiana The fruit is a non-tropical Guava, that is thought to have a taste similar to a Pineapple. In my experience, each variety will vary, and the more common Nazemetz taste like a cross between a mint and a rose. 
This plant is easy to grow, has beautiful leaves, and is hearty enough to survive the So.Cal heat, and lack of moisture. All the Varieties are a bit different, and the ones that I grow on my property are Mammoth, Nazemetz, and Coolidge. Here’s a list of Pineapple Guava Cultivars: CULTIVARS Apollo Medium to large, oval fruit. Smooth, thin, light-green skin with blue-green surface bloom, subject to bruising and purpling. Pulp well-developed, slightly gritty. Flavor very pleasant, quality excellent. Ripens mid to late-season. Tree upright and spreading, to 8 ft. tall, vigorous and productive. Self-fertile, and will pollinate Gemini. Choiceana Originated in Australia. Small to medium-sized, round to oval fruit, 2 to 3-1/2 inches long. Skin fairly smooth. Flavor and quality good. Ripens in midseason. Tree moderately vigorous, spreading. Almost or always, but not less than 42% self-fertile. Coolidge Originated in Australia prior to 1908. Small to medium-sized fruit, 4 or more inches in length and 2-1/2 inches in diameter. Form pyriform to oblong or elongated. Skin somewhat wrinkled. Flavor mild, indifferent quality. Tree upright and strong growing, a reliable and heavy bearer, 100% self-fertile. The most widely planted cultivar in California. Edenvale Improved Coolidge Originated in Santa Cruz, Calif. by Frank Serpa of Edenvale Nurseries. Large, oblong fruit of very good to excellent flavor and quality. Ripens in October. Tree slow growing. Self-fertile, precocious and productive. Grows best in climates similar to cool, coastal ares of southern California. Edenvale Late From Edenvale Nurseries. Mediuim-sized, oblong fruit of very good to excellent flavor and quality. Ripens late, in January,and over a long period of time. Tree slow growing. Self-fertile, very productive. Grows best in climates similar to cool, coastal areas of southern California. Edenvale Supreme From Edenvale Nurseries. Medium-sized, oblong fruit of very good to excellent flavor and quality. Ripens in November. Best eaten soon after harvest. Tree slow growing. Self-fertile, precocious and productive. Grows best in climates similar to cool, coastal areas of southern California. Gemini Fruit small to medium, egg-shaped. Skin very smooth, thin, dark green with a heavy bloom. Flavor and texture excellent. Ripens in early autumn, earlier than Apollo. Tree upright, spreading, to 8 ft tall. Moderately vigorous, high yielding, partially self-fruitful, but cross pollination is recommended for best fruit quality. Mammoth Selected in New Zealand from seedlings of the Choiceana. Large, round to oval fruit, to 8-1/2 ounces, resembling Coolidge. Skin thick, somewhat wrinkled. Flesh somewhat gritty, quality and flavor very good. Matures early in midseason. Softer and not as good a shipper as Triumph. Tree of upright habit, to 10 ft. tall, strong growing. Self-fertile, but bears larger fruit, with cross-pollination. Moore Large, flavorsome fruit. Ripens in midseason. Very vigorous plant. Recommended for California. Nazemetz Originated in San Diego, Calif. by Alexander Nazemetz. Large, pear-shaped fruit, averaging 3 ounce in weight. Side walls moderately thin. Pulp translucent and sweet. Flavor and quality excellent. Ripens in late October to mid-December. Unlike that of many other cultivars, the pulp of Nazemetz does not darken after being cut or as it ripens, but retains its clear color. Tree self-fertile, but bears most heavily when cross-pollinated. Good pollinator for Trask. Pineapple Gem Originated in Azusa, Calif. by Monrovia Nursery. Small, round fruit of good to very good quality. Mid to late season ripening. Tree self-fruitful but bears heavier crops if pollinated. Does poorly under cool, coastal conditions. Trask Originated as a bud sport of Coolidge. Medium to large, oblong fruit, up to 3-1/2 inches long and weighing 3 to 5 ounces. Rough, dark green skin. Shells thicker and grittier than Coolidge. Flavor and quality good to very good. Ripens early. Tree self-fertile, but most productive when cross-pollinated. Precocious. Ideal pollinator for Nazemetz. Triumph Selected in New Zealand from seedlings of the Choiceana cultivar. Short, oval, plump fruits., not pointed as those of Coolidge, medium to large. Skin uneven but firm. Flesh somewhat gritty but with good seed to pulp ratio. Excellent sharp flavor. Ripens to midseason. Tree upright, of medium vigor. Bears heavily if pollinated. Good pollinator for Mammoth. This is considered a “Non-Tropical” Guava, and falls in a similar category as other Non-Tropical Guavas such as Strawberry Guava & Lemon Guava. If you live in Southern California, then go for the Tropical Guavas! You might like the ability to eat the flower pedals of the Pineapple Guava, but the size of these fruit are very small, and most of them need a pollinator, which means you need to buy 2 different varieties of Pineapple Guava to get an abundance of fruit. 
These guys look like Guavas when you crack them open, but do not have that “Tropical” or “Hawaiian Punch” knock-out flavor. That Starburst style burst of Guava flavor is not present in any of the Pineapple, Lemon, or Strawberry Non-Tropical Guavas. But if you wanna munch on some flower pedals during a nice spring day in April, then a Pineapple Guava could fit the bill. 
And the flowers are sure perdy….
