The Demeter software was developed by NCCPG Plant Heritage to provide National Plant Collection Holders with facilities to record information about their plants in a consistent, accessible way. A wide range of Collection Holders were involved in its design and it is suitable for all kinds of plants in all sorts of gardens. It is comprehensive, flexible and easy to use.
The development was funded by a grant from the Heritage Lottery Fund together with financial and practical support from the Royal Horticultural Society, the National Trust, National Trust for Scotland and English Heritage. The RHS provided a list of over 100,000 plant names from the Plant Finder database.
The funding from the HLF enabled Plant Heritage to provide Demeter free of charge to National Plant Collection Holders. Demeter remains free to National Plant Collection Holders to this day.
