The Rhododendron, Camellia & Magnolia Group

Three groups of plants – one group of enthusiasts worldwide


The 2016 Red List of Magnoliaceae (published 18 March 2016) highlights the startling truth that many species in this treasured plant family are at risk of going extinct. The Red List of Magnoliaceae presents conservation assessments conducted by experts for 304 wild magnolia species from around the world. The assessments have been carried out using the IUCN Red List Categories and Criteria, an internationally recognised and widely used system for classifying species at risk of extinction.

A quarter of the world's rhododendrons are threatened with extinction in the wild. The Rhododendron Red List, published jointly by Botanic Gardens Conservation International (BGCI), Fauna & Flora International (FFI) and Royal Botanic Garden Edinburgh, in June 2011 identifies 317 rhododendrons as being in danger of extinction, out of a global total of 1157 taxa evaluated. The members of the IUCN/SSC Global Tree Specialist Group, for which BGCI provides the Secretariat, and rhododendron experts around the world contributed much of the information for this Red List report.

A mention of the condition of the plant would be really helpful in order that a propagation programme may be started, if possible. Any other comments on the list would be welcome, especially if you think a plant is not worth saving.

Shimane Azalea Project

The Shimane Azalea Project is an international collaborative study between Japan and the UK, starting in 2018 and continuing beyond 2020. The project is led by Professor Nobuo Kobayashi of the Shimane University in Japan. He and his team of researchers have carried out and published a great deal of research into 'Tsutsuji' (azaleas). He has been collaborating with Italy and Belgium for over 15 years. This year, 2018, is the first year that the UK is involved.
