Feijoa is an evergreen tree-like shrub with silver green leaves and pink/red fluffy flowers in Summer. Feijoa Sellowiana or Pineapple Guava has one of the most exotic flowers you will find that is hardy enough to grow in our UK climate. It is drought tolerant once established, but a lack of water will cause fruit to drop off. Feijoa does not like to be kept too wet. The rather exotic looking flowers come in early summer and have fleshy petals. Widely cultivated in New Zealand, this evergreen prefers sheltered partially shady areas.
