In the years 2000-2010, observations were made of shrubs of the varieties derived from the Pimpinellifolia (R. pimpinellifolia L.) gathered in the Collection of Rose Culti- vars of PAS Botanical Garden in Powsin, Poland. The nine observed varieties were 'Aïcha', 'Elegans', 'Frühlingsduft', 'Frühlingsgold', 'Frühlingsmorgen', 'Harison's Yellow', 'Maigold', 'Poppius', and 'Stanwell Perpetual'. Every year, the following were recorded: frost damage; the date of bud breaking and the date when leaves developed in springtime; the date of the initial, complete and final flowering; the presence of symptoms of damage from disease and pests; the ability to create decorative fruit, and remarks concerning the necessity to perform spring cutting and cutting after flowering. The winter seasons of 2002/2003, 2005/2006 and 2009/2010 were unfavourable for the roses. The cultivars varied greatly according to the examined features. The advantages of many of the varieties include high frost resistance, early flowering, low requirements in terms of cutting, good condition; and the fact that some varieties create suckers ('Elegans', 'Harison's Yellow', 'Poppius', 'Stanwell Perpetual'). The varieties 'Aïcha', 'Elegans', 'Frühlingsduft', 'Frühlingsgold', 'Poppius', 'Stanwell Perpetual' are the most frost resistant. The least frost-resistant variety is 'Maigold'. The first to flower are 'Harison's Yellow', 'Frühlingsmorgen' and 'Poppius'. Varieties derived from Rosa pimpinellifolia can be widely used as park roses, as ground covers, and as soil protective roses ('Elegans', 'Harison's Yellow', 'Poppius', 'Stanwell Perpetual').
