Pavement Prowl, searching and discussing pavement and gutter plants in the Tulse Hill area, London Borough of Lambeth, starting at 11 a.m.  For further details see the Events page on this website.

Report:  18 people turned up for this walk and spent about 90 minutes contributing to our discussions on pavement and gutter plants, many of which originated in lands far from Britain.  Thus we were able to examine such plants as Argentine vervain (Verbena bonariensis), Mexican fleabane (Erigeron karvinskianus), red valerian (Centranthus ruber) from the Mediterranean region, and procumbent yellow sorrel (Oxalis corniculata), now widespread but thought to be native to southeastern Asia (not South Africa, as the leader thought!).

‘Enjoyed the walk, very interesting; a nice lot of people.’
