Abstract
In the years 2000-2011, observations were made of shrubs of the cultivars derived from the Rugosa (<i>R. rugosa</i> Thunb.) gathered in the Collection of Rose Cultivars of the Polish Academy of Sciences (PAS) Botanical Garden – Center for Biological Diversity Conservation (CBDC) in Powsin, Poland, including 29 cultivars. In the first part, the results are presented for 12 historical cultivars (‘Agnes’, ‘Belle Poitevine’, ‘Blanc Double de Coubert’, ‘F.J. Grootendorst’, ‘Frau Dagmar Hastrup’, ‘Hansa’, ‘Kaiserin des Nordens’, ‘Max Graf’, ‘Moje Hammarberg’, ‘Mrs Anthony Waterer’, ‘Pink Grootendorst’, ‘Rugeaux du Japon’). Every year, damage to shrubs caused by frost was recorded; the date of bud break and the date when leaves developed in springtime were recorded; regeneration of shrubs damaged in winter was observed; the dates of initial, full and final flowering were recorded; the presence of disease symptoms was observed; and notes were made concerning the need to do spring pruning and pruning after flowering. The winter seasons 2002/2003, 2005/2006, 2009/2010, 2010/2011 were unfavourable for roses. In terms of the features in question, the cultivars varied. The cultivars derived from the Rugosa should find a wider application as park roses (‘Agnes’, ‘Belle Poitevine’, ‘F.J. Grootendorst’, ‘Frau Dagmar Hastrup’, ‘Mrs Anthony Waterer’, ‘Pink Grootendorst’, ‘Rugeaux du Japon’) as well as ground cover and soil protection roses (‘Blanc Double de Coubert’, ‘Hansa’, ‘Kaiserin des Nordens’, ‘Max Graf’, ‘Moje Hammarberg’) planted in urban green areas and near historical buildings.

IntroductionThe Rugosa (Rosa rugosa Thunb.) belongs to the species-richest subgenus Rosa (Eurosa) in the section Cinnamomeae DC (Popek , 1996)
In the years 1998-2011, the Collection of Rose Cultivars in the Polish Academy of Sciences (PAS) Botanical Garden in Powsin gathered more than 700 species and varieties of roses, out of which 35 are Rugosa hybrids
The observations were made on shrubs growing in the Collection of Rose Cultivars of the PAS Botanical Garden Center for Biological Diversity Conservation (CBDC) in Warsaw in the years 2000-2011
Summary
The Rugosa (Rosa rugosa Thunb.) belongs to the species-richest subgenus Rosa (Eurosa) in the section Cinnamomeae DC (Popek , 1996). It comes from the seashores of the Far East (Korean Peninsula to Sakhalin) and occurs in the natural environment in Poland as an alien species (Bugała , 2000). Can withstand frost of up to -35oC (Jerzy et al 1992) in 2 planting zones (Heinze et al 1984) and are highly resistant to air pollution, drought, poor soils, salinity as well as salt sprinkled on roads (Popek , 2002) For those reasons, it is recommended for locations which are not very favourable for the growth of plants, e.g. along transport routes, on slopes, mounds, dunes, which it strengthens by expanding through suckers. It is recommended not to be cultivated in protected areas and their buffer zones (www.iop.krakow.pl)
