Benefits of Membership

The Society is trying to reduce costs, global footprint and the time and effort required to run the Society by using electronic communication whenever and wherever possible. The main exception to this is our annual journal, Clematis International. We ask all members, existing and new, to only request hard copy if there really is no other option. Thank you.

Members of the Society receive a copy of the Society's publication, 'Clematis International', as well as a minimum of two newsletters a year (normally) containing details of the Society's activities and offering participation in the Seed Exchange, a means by which members are provided with the opportunity to grow varieties of Clematis often unobtainable in their own country.

A Membership List is normally issued annually, enabling Members to contact one another.

The International Clematis Society is affiliated to the Royal Horticultural Society of the United Kingdom.

The Seed Exchange

Members can take advantage of seeds being offered by the Society and, of course, contribute seed to the Seed Exchange, giving the opportunity and fun of trying something new and exciting from other countries.

Requests for donations of seeds are sent out in September/October, with the Seed Exchange List itself available from February/March the following year.

International Clematis Registrar

The Society works closely with the International Clematis Registrar for Clematis. It encourages members to assist personally by providing details of old and new cultivars so that the register of names can be as complete as possible.
