....It cannot identify a historic variety, if we don't have a known specimen of the historic variety to work with. For example, there are several candidates for the "true" 'Slater's Crimson China' in commerce. We can easily determine if those candidates are closely related to each other. But, lacking the original, guaranteed "true" 'Slater's Crimson China', we can never hope to prove that any one of the extant roses is the real thing.

In the logo is the rose 'Slater's Crimson China' as we now know, then only known by its local name "Belfield". It was designed by Lady Conyers in 1955 and appears on our stationary, our membership pin, etc. Mr. Richard Thomson, the well-known rosarian, came to Bermuda in 1953 to visit Mrs. Laura Pattisson. She showed him all the roses she knew and also this little red rose growing against a wall of a slave cottage, named Belfield, in Somerset. He was very excited and took samples home for scientific verification. when he returned in July 1956 for a lecture he confirmed that this little red rose was indeed 'Slater's Crimson China'.

Rosa indica One of the roses Josephine grew at Malmaison and that is still available today...Until its introduction from China and northern India, Western gardens never had a rose capable of blooming from month to month. R. indica caught the eye of Joséphine's gardeners, who began to cultivate new hybrids... the China rose... Rediscovered in Bermuda in the 1950s, R. indica is now called 'Belfield', after the estate where it was found...
