Mike Brown is a member of the International Clematis Society and is a past Chairman of the British Clematis Society (BCS); he has written many articles on the genus. Mike is the raiser of the popular clematis 'Barbara Wheeler' and has just named a new cultivar 'Geoffrey Tolver'.

For many years Mike has been involved in organising the annual BCS seed exchange programme and in trialling new clematis for BCS awards. Mike holds the UK's NCCPG National Collection of herbaceous clematis but his collection extends far beyond this.
