Geranium ibericum x platypetalum (G. x magnificum)
A clump-forming perennial herb, occurring in the wild as a long-persisting escape or throw-out on roadsides, railway banks and waste ground. Lowland.
This sterile hybrid is popular amongst gardeners for its striking blue-purple flowers and ground-covering abilities. It was first recorded in the wild in 1932 (Middlesex) and is probably increasing. The lack of records from Ireland is surprising.
A hybrid of garden origin; both its parents are found in the Caucasus.
