Notes: Bridal Veil was first recorded as a garden plant in Australia in 1870. It has now escaped from gardens in Western Australia, South Australia and Victoria. Plants naturalised in Victoria are now believed to have been eradicated. Shoots emerge after autumn rains and above ground parts dry off with warm temperatures in summer. The dense foliage and root mass of A. declinatus inhibit growth of other species.
