International Dendrology Society

The IDS is a specialist route when tree research needs to go beyond a short nursery description. Start with Trees and Shrubs Online for a reference task, or the yearbooks and study activities for a broader interest in woody plants. The society connects horticultural enjoyment with conservation, so its material can help place a garden tree in a wider botanical context. Membership events and tours serve a different purpose from an immediate plant lookup. Establish whether the question concerns a name, a growing requirement or a collection before choosing the next resource.
