Bengt Schalin liked Scots roses, such as 'Poppius' with its pink flowers. It grows in many of Helsinki's old parks. It blooms for a couple of weeks at the end of June, after Rosa pimpinellifolia 'Plena'. 'Poppius has its origins in a Swedish cultivar from the 1850s. It fell into complete obscurity in Finland after the 1950s. Some old shrubs preserved in Helsinki's parks and elsewhere in Finland were identified and named "suviruusu" in the 1980s. It has been put on the market in the range of high-quality Finnish FinE plants.
In Helsinki there are 'Poppius' roses to be found in Kaivopuisto Park, on Tähtitorninvuori and in Onnenpuisto Park in Käpylä. There are younger shrubs in places like the Meilahti arboretum and Aarrepuisto Park in Vesala.
