Acca–commonly called pineapple guava–is a subtropical evergreen shrub cultivated for its colorful cup-shaped flowers and in warm regions for its edible fruits. Acca is sometimes listed under its previous genus name Feijoa.
Acca flowers are more than an inch across; they have long red stamens and purple-red petals that are white on the margins. In subtropical regions, the flowers are followed by small egg-shaped fruits that are edible. Fruits ripen 4 to 5 months after flowering.
Acca fruits are soft and sweet with a slight pineapple-flavored pulp. The fruits are sold under the names “feijoa” or “guava.”
Acca is often grown as a hedge or as a colorful specimen. It is usually multi-stemmed. It tolerates dry, sandy soil and salt spray, but it does not tolerate wind.
Acca is a genus that contains two or three species of evergreen shrubs from dry habitats in South America subtropics. Only one is commonly grown, for its showy midsummer flowers and for edible fruits in the southern part of its range.
