Natives for my pohutukawa

a variety of natives will grow well under your established Pohutukawa tree assuming it is shady, such as: Arthropodium ciratum spp (Renga renga lilies) (mass plant in a large numbers for a bold effect when the flower in spring), Astelia banksii, Asplenium bulbiferum (hen and chicken ferns) Libertia grandiflora (native Iris), and Macropiper melchior.
