All our finger lime trees were grafted from the same certified 'Rainforest Pearl' parent stock. Never did we image that so much colour variation would occur within the one variety! This phenomena has been widely reported. It is thought that each tree responds differently to slight variations in soil, water and microclimates within a paddock. It is all part of the mystery of 'Citrus australasica'.
We have also noticed that there is slight variation of flavour within the colour range. The limey colours are tart and refreshing and great for dishes requiring high acid levels, like ceviches and currys. The pinker, redder ones are more fragrant with a higher sugar level. They are lovely as a garnish for seafood and in desserts.
