Tropical Guava Ruby Supreme. Considered by many to be one of the best guavas for the home garden. This highly productive cultivar produces pear-shaped, yellow skinned guavas with thick, pink flesh. Lower in pectin than other varieties, this variety is superior for eating out-of-hand or processing into juice. In spite of its common name, the tree is cold hardy for a tropical fruit. Very reliable, heavy producer. Will fruit in container.
