This is a gardeners’ and plant breeders’ grouping, well-defined at its centre but rather fuzzy at the margins, for some ornamental hybrids of M. sieversii f. niedzwetzkyana, especially with M. baccata. Intensely coloured flowers are a sine qua non; heavily pigmented leaves, large flowers and severe scab susceptibility are very common, but not universal features. Hybrids of this sort made in the early decades of the 20th century by Nils Hansen at the State Agricultural Experiment Station, Brookings, SD, and by Isabella Preston of the Canada Department of Agriculture, Ottawa, Ontario are consistently placed here (Fiala 1994). We describe Hansens’s ‘Hopa’, and Preston’s ‘Cowichan’, ‘Makamik’ and ‘Simcoe’. Later hybrids with similar characteristics (e.g. ‘Almey’, ‘Royalty’, ‘Rudolph’ and M. × moerlandsii cultivars such as ‘Liset’ and ‘Profusion’) are sometimes also referred to as rosyblooms, but it is not really clear where the term should end.
