  The presence of Spiraea media on the Balaton Uplands has high plant geographical importance, but the found location has not been known before its recent rediscovery. The Spiraea media was discovered on the Kopasz Hill (Felsőörs) growing in a closed Quercus cerris oak forest (~Fraxino orni-Quercetum cerridis); which is a rather atypical habitat of the species. The appearance of blooming specimens and the rediscovery of the species is probably due to the cut of the neighbouring forest, which has resulted extra irradiation in the area. The 19^th century military maps of the landscape show that the former vegetation of the area was characterised by the mosaics of rocky grassland–scrub–forest or rocky scrub rich patches being suitable for the species.
