The Drive was planted in 1929 with 400 pohutukawa and 100 Norfolk Island pines. The intention in planting Norfolk Island pine (Araucaria heterophylla) to flank the pohutukawa was to make the latter grow inwards towards the sunlight and form an archway above the road. The pohutukawa (Metrosideros excelsa) is famed for its brilliant red flowers which bloom for a month or so close to Christmas, giving rise to its common name "New Zealand Christmas Tree". Also of special interest is a yellow-flowering pohutukawa growing close to the restaurant. This is a naturally occurring variant of the same species.
