Herbarium Specimens from RHS Plant Trials

Trials have been an important part of the RHS’s work since 1860.

The Herbarium at RHS Garden Wisley currently contains over 8,000 specimens collected from different trials, and this number is growing all the time. The oldest trial specimen in our collection is a Salix acutifolia 'Pendulifolia' dating back to 1966!

Below you can find links to collections created to highlight specimens gathered from recently completed trials. If you would like more information about these trials, please visit the RHS Plant Trials and Awards website pages.
