On top of 14 individual first places, they won the Rosemary Cobbald-Sawle Cup for the best exhibit in Class 1, the Louis Reid Cup for the most points accrued for ornamental trees and shrubs, the Mrs Charles Williams Cup for the most points scored for Rhododendrons and, for the 17th time in 51 years, the coveted Banksian Medal, awarded by the Royal Horticultural Society, for the most points scored throughout the show.

Trewithen's 46 displays were entered in four sections of Cornwall Garden Society's spring two-day show held at Bocconoc last weekend.

Michael Galsworthy, owner of the estate situated between Truro and St Austell, was absolutely delighted with the result, particularly the Rhododendron class in which nine of Trewithen's 14 entries won first place.

He said: "The team, lead by Head Gardener, Gary Long, has done a magnificent job. We entered more classes than ever before and I think it may have been our most successful spring show ever as well."

Gary put part of the success down to the fact spring has come to Trewithen a few weeks later than in recent years and the flowering trees and shrubs the garden is so famous for are particularly vibrant and beautiful.

He said: "The Cornwall Spring Flower Show is always the competitive highlight of our horticultural year when all of the county's gardens get a chance to show off what they do so well. There's some healthy, good-spirited competition which produces outstanding exhibits, particularly this year. I even overheard one visitor saying that the displays were better than the Chelsea Flower Show but on a smaller scale."

A dedicated display cabinet is now being built so visitors to Trewithen Gardens will have a chance to see the medal, cups and certificates awarded during this year's Cornwall Spring Flower Show.
