Rubus fruticosus agg.
Deciduous or semi-evergreen shrubs of woods, scrub, banks, hedges, heaths and waste places. They can form dominant stands and although they have a very wide ecological tolerance they reach maximum vigour and diversity on acidic soils. They spread by bird-dispersed seeds, and by tip-rooting stems. 0?490 m (Harwood, Co. Durham).
R. fruticosus is a taxonomically intractable aggregate of over 320 microspecies in Rubus subgenus Rubus (except R. caesius), most of which are facultatively apomictic. There is no change in the distribution of the aggregate since the 1962 Atlas.
European Southern-temperate element.
