Warndu's Lemon Aspen

This is a type of citrus bearing small edible fruits that taste like a cross between a lime and a grapefruit with a hint of conifer. It is a rich source of folate, iron and zinc, and also contains magnesium and calcium. Because the lemon aspen is a rainforest species, the fruit may sometimes be referred to as ‘rainforest lemon’. This tree is native to Far North Queensland, but will grow as far south as Sydney and even in South Australia.

A tart, lemon taste with a little spice and eucalyptus flavour. This makes a wonderful addition to anything needing a citrus kick, sweets, broths, sauces, teas and cocktails.

Traditional Aboriginal Food and Uses

Lemon Aspen fruit have been used by the Aborigines for thousands of years for both medicinal and culinary purposes.

It was regularly consumed by Indigenous communities in north eastern Queensland, and there is some continuing involvement in its cultivation in far north Queensland.

Western & Modern

Lemon Aspen can be supplied to consumers as fresh fruit but due to its relatively short season it is more commonly available to the market as juice and whole frozen fruit. It is also dried and ground into a spice that is used in a wide variety of dishes, including baked goods.

Lemon Aspen is used in a similar way to produce cordials and syrups, juices, mineral water, fruit wine and even glazed fruit and confectionary. Very popular in the food industry, the fruit pulp and juice is also used to make a large range of sweet and savoury dishes as well as sauces, dressings, preserves, chutneys and relishes, and mayonnaise.

Extracts of the fruit can be used in skin care, anti-aging cosmetics, skin repair, hair care and sunscreen. As with numerous native fruits, lemon aspen has superior antioxidant capacity compared to blueberry; it is rich in folate, iron and zinc (compared with some other native fruits) and it contains magnesium and calcium.


Rich in antioxidants, lemon aspen provides important daily vitamins and minerals essential for the body in the following ways:

  • Boosts the human immune system
  • Reduces the risk of flu and common cold
  • Protects the skin from damaging UV rays
  • Can reduce and repair the visible signs of ageing
  • Promotes wound healing
  • Amplifies the synthesis of collagen
