In this webinar, Emily Conn and Eileen Gahan will be sharing details of their IDS tour to central China, where they travelled through a variety of ecosystems and biodiversity hotspots. From the old city of Xi’an, through the Qinling and Daba Shan mountains, and into the Shennongjia National Geopark, discover the landscape that harbours some of the world's most spectacular and ancient forests.
Eileen Gahan holds a Hort. BSc from the National Botanic Gardens, Glasnevin, where she was mentored by Seamus O’Brien, Head Gardener at Kilmacurragh. In 2024, she interned for Maurice Foster at White House Farm and at RHS Wisley, where she maintained the Woodland Broad Walk. She is currently researching Aucuba omeiensis as part of her ongoing Masters in Horticultural Science at North Carolina State University, under the mentorship of Mark Weathington, Director of the JC Raulston Arboretum.

Philippe de Spoelberch will discuss seven main species of Stewartia in cultivation in temperate gardens, along with selected subspecies and varieties.
The collection of Stewartia at Arboretum Wespelaar started with a shipment of cutting material from the Polly Hill Arboretum in Martha's Vineyard during the 1990s. This was highly successful and these cuttings, with seedlings from the Arnold Arboretum, constitute the base of the collection. Of 320 accessions introduced over the last 40 years, some 200 are alive. Floral displays may be discrete but bark and autumn colours are truly spectacular.
