Annual of damp fields and ditches with pink spikes that give bees late-season nectar and pollen from late summer to October.
Redshank is an annual weed with dense pink spikes, often with a dark blotch in the middle of the leaf. Its small flowers have open nectaries; honey bees visit them regularly for nectar and pollen. Nectar secretion depends heavily on soil moisture: it is marked in irrigated fields and along rice paddies and canals, and weak on dry soils.
From late June to October, flowering profusely especially on fields after harvest and among irrigated maize and beet.
It is not harvested as a separate honey; it goes into autumn mixed honey. The nectar of knotweed species can darken the honey.
In autumn it is useful for supplying pollen and nectar while winter bees are being reared. As an arable weed it is destroyed with herbicides; it survives in damp field margins.
