In many countries there are groups that organise the creation and maintenance of plant collections, for conservation purposes. Originally, plant collections were developed within the confines of botanic gardens, as part of basic botanical and taxanomical research. However, the growing importance of hybridisation and, more recently, cultivar development has meant that increasingly this responsibility has moved into the public arena. Today, the formality of these arrangements and the degree of support they obtain from government varies from place to place.

In the United Kingdom, the world's leading plant collections group, the National Council for the Conservation of Plants and Gardens (NCCPG) organises National Plant Collections® throughout the country. In 1999 the NCCPG celebrated its 21st anniversary and the fact that it now oversees some 600 National Plant Collections®.

Elsewhere in the world other groups carry out similar roles. In Australia, the Ornamental Plant Collections Association (OPCA) maintains some 70+ collections. In France, Le Conservatoire des Collections Végétales Specialisées (CCVS) organises some 130+ collections. In the USA there are two organisations at work: The Northern American Plant Collections Consortium (NAPCC), formed through the AABGA, focuses on National Collections within institutions and the North American Plant Preservation Council (NAAPPC) on Collections held by individuals and within commerce.

In addition to the existing schemes, individuals and groups are helping to develop similar approaches elsewhere in the world. In Poland, Dr. T. J. Nowak, from Wroclaw Botanic Garden is striving to protect original stock from what remains of the country's historic gardens. Last, but by no means least, similar schemes are under development in Belgium, Germany, New Zealand and Sweden.

The importance of Clematis as a genus is reflected in all of the schemes, normally by a discrete collection of some part of the Clematis genus.

National Plant Collections® in the United Kingdom

The NCCPG organises National Plant Collections® in the United Kingdom. In their words, their Mission is:

"Through volunteer membership, the NCCPG seeks to conserve, document, promote and make available Britain's great biodiversity of garden plants for the benefit of horticulture, education and science"

The collections are held by a mix of dedicated individuals and organisations and are organised by genus. Most collections can be viewed by members of the public. Further details of these and other collections can be found in the National Plant Collections® Directory, which can be obtained from the NCCPG, The Stable Courtyard, RHS Garden, Wisley, Woking, Surrey, GU23 6QP, Tel: 01483 211465.

Clematis are well represented amongst the National Plant Collections; and the current collections are outlined below. All National Plant Collections; are open to the public but some, due to location or size, have restricted access and you will have to write to the collection holder to make arrangements for your visit. Although opening times are shown, these may vary and are subject to the holders rights to change at short notice and active confirmation should be sought before making any journey.

Ornamental Plant Conservation Association of Australia

OPCA celebrated its 10th Anniversary in 1999. It was formed using the UK's NCCPG as a guide, with the primary aim of searching out, identifying and propagating some of the many plants once available in the horticultural trade, but now lost or growing 'hidden' in old gardens. Most of the 70+ registered Collections are based in Victoria, but interest is growing inter-state.

OPCA is based at the Royal Botanic Gardens, Melbourne, Birdwood Avenue, South Yarra 3141. Telephone: (03) 650 5639. Fax: (03) 655 2350
