Feijoa sellowiana
Feijoa, or pineapple guava, grows to eighteen to twenty-five feet, usually as a multi-trunked shrub. It can, however, take considerable pruning, making it ideal for hedges, espaliering or training as a small tree. The leaves are grey-green on top and silvery underneath. Flowers are white with red stamens and are edible. Feijoa can produce fruit that is also edible. It is drought tolerant, but will do better with some water.
