White-fruited rowans of subgenus Albocarmesinae McAllister have been cultivated at Peter the Great Botanic Garden of the Komarov Botanical Institute RAS (Saint-Petersburg, Russia) since 1951. There are 3 species of section Multijugae (Yu) McAllister in modern collection: Sorbus cashmiriana Hedl., S. eburnea McAll. and S. frutescens<.I> McAll., since 1999. Nowadays all of them produce fruits (since 2008). And since 2012 the seed reproduction of the second generation has been obtained and cultivated. They are quite winter hardy in local climatic conditions and are of exclusive interest for decorative gardening and city planting. Because they are apomicts, this is possible to propagate them in large scale by local seeds.
