Rubus species. I thought the local blackberry menace was Rubus fructicosa aggregate - but couldn't find it. We have got rid of most of this infestation but we still find patches that seem to appear from nowhere! Photo by A. Reichstein.
Rubus fruticosus agg. has been split into its component species. R. anglocandicans has high arching canes. The others have to be mainly IDd on flower details. We had some discussion on whether Rubus should be with climbers or shrubs, and decided on shrubs for CNM. Some species of Rubus in the ALCW area are definitely climbers.
