The trees were grown at the college from a small-leafed elm found near Great Comberton, Worcestershire, which was found to been resistant to Dutch elm disease.
John Clarke, conservation advisor to nearby Kemerton Conservation Trust, set up an organisation called RELIC, Replanting Elms in the Countryside, a few years ago.
Previously Clarke had considered the idea of replanting elms in the British countryside a "pipe dream".
Clarke worked with Bob Hares, Pershore's RHS adviser, to collect cuttings and propagate the elms at the college. These are the first to be planted in Worcestershire.
