E. B. Le Grice, North Walsham. Sanders White – A tiny white rambler of true wichuraiana type. The small glossy leaves and slender, wiry shoots are evergreen. The pure white blooms are strongly perfumed with the typical scent of R. wichuraiana. The variety is excellent for screening purposes, being hardy and healthy. Prune as for Alberic Barbier. I think the less known Snowflake is an improvement on Sanders’ White, to which it is very similar.

Of new varieties we are experimenting with the latest climbers produced and testing them all as weeping standards, e.g., Irene Bonnet, Jacotte, Violetta, Albertine, Yvonne and Snow- flake. The latter particularly looks promising, with its snow white flowers and wonderful foliage...Oxted. Herbert I. Wettern.
