New Zealand Hybrids and Registration


There are many named New Zealand hybrids widely distributed and readily available, however there are several that have not been registered. We encourage those who are associated with such plants to consider formally registering them in order to ensure that the name is protected and to provide a suitable provenance for future rhododendron growers.

A Practical Guide For Growing Rhododendrons

Vireya Rhododendrons

Vireyas are a group of approx. species of rhododendrons which grow predominantly in tropical mountainous areas ranging from 1200 to 2400 metres. They can be found mostly in Malaysia, Indonesia, Phillipines, Papua New Guinea and North Queensland with some also in NE India and Vietnam. Most vireyas are epiphytic in cool montane forests but higher altitude species grow in the ground. Many species and hybrids flower more than once during the year.

Ex Situ Species Project

The ex situ  project is a collaborative initiative involving the Pukeiti Rhododendron Trust, Massey University, NZ Rhododendron Association, and Taranaki Regional Council. Its primary aim is to contribute to global ex situ conservation of threatened Rhododendron species by managing the 'New Zealand' Rhododendron collection.  In this project we collaborate with partner collections to cultivate rhododendrons on multiple sites throughout New Zealand.
