The results of major trials are now being produced in full colour bulletins. They include full descriptions of the Award of Garden Merit plants, comprehensively illustrated. Background botanical and cultivation information is also included as are useful selection tables, comparing the different entries in the trial.
The bulletins are compiled by the scientific and horticultural staff at Wisley, with advice and assistance from our Plant Committees.
If you would like a printed copy please contact: The Trials Office, RHS Garden Wisley, Woking, Surrey GU23 6QB. Please enclose a large A4 self-addressed envelope. They cost £2 per copy (a donation towards costs); cheques to be made out to Royal Horticultural Society.
