How to choose Guavas: The most important thing to consider when choosing a guava is the smell. Find a guava that smells sweet and it will taste good. Some discolorations on the skin are OK, just avoid any fruits with obvious damage or rotting. A guava will yield when mild pressure is applied and this is a sign that the guava is ripe and ready to eat.
Climate and origin: Guavas originated in tropical portions of Central and South America, and are now widely cultivated in tropical climates all over the world. (zones 8-10 in the U.S.) Guava is a hearty plant and can be grown under green houses in colder climates.
Taste: Guava has a fragrant sweet taste and a mushy texture.
Miscellaneous information: The amount of vitamin C in guavas varies by type. Notably, a Strawberry Guava contains less than a quarter of the vitamin C found in a Common Guava.
