This climbing, sprawling annual, found in arable, disturbed fields and banks, bears white or cream flowers in long crowded spikes (up to 20 flowers) from May to September. These short-stalked flowers (10-14mm long) have the upper petals compressed and the lower petals have rolled-up edges. The upper petals are tipped with deep purple and the flowers have two small toothed obtuse sepals. The alternate leaves are pinnate and cut into numerous segments. Stems, which tend to ramble across other plants, can be up to 80cm long. This is not a native Irish plant and is a member of the Papaveraceae family.
I found and photographed this plant growing in Dalkey, Co Dublin in 2009.
