How it is grown

Prefers a rich moist soil with some shade in summer. The crushed leaves smell strongly of celery. This plant used to be known as A. australe, along with a New Zealand form and a S. American form. Most botanists now only apply that name to the S. American form, the New Zealand form has been moved to A. filiforme (syn A, prostratum filiforme) whilst this Australian form is now known as A. prostratum. This plant has been suggested as having the potential to be bred as a cultivated vegetable.
