This is the most difficult group to classify and contains all those roses that are not bush or bedding roses, climbers or ramblers (Hybrid Teas and Floribundas); they generally all have a long flowering season. Any selection of groups here will involve overlap with others.To compound the problem many roses under this broad heading are categorised according to the supplier, so we have, for example, David Austin, Beales, Harkness and Meilland® roses. Sometimes trademarks have taken a strong hold as with the Flower Carpet® and Meidiland® series. In general terms modern shrub roses, because of their size or habit, are unsuitable for bedding.
