Welcome to Plant Heritage's Threatened Plants Project
The Threatened Plants Project aims to identify all known cultivars in British and Irish horticulture; calculate which have become rare and threatened in cultivation today; gather information from referees and literature to assess Plant Heritage Value for each; and develop conservation plans with partner organisations for the most worthy cultivars.
This is for hardy and tender plants, trees, ferns, fruit and seeds which come true to name, across England, Wales, Scotland, Ireland, the Isle of Man, Guernsey and Jersey.
373 genera have been entered into the process and threatened in cultivation status calculated for 275. Information is being migrated to this database but much more is held - please contact for further details.
