Field bindweed (Convolvulus arvensis) can be a little deceiving in that the flowers can be pure white, pure pink or a combination of the two! It can be told from the hedge bindweed and large bindweed primarily because it has a smaller flower and tends to be prostrate on the ground rather than entwined in hedges. Sea bindweed has flowers of similar size and colour but sea bindweed grows on dunes and shingle by the sea; field bindweed can occur near the sea too!
All the bindweeds are pretty vigorous weeds and they are somewhat despised which is a shame as they have lovely flowers but they really can be a problem and virtually impossible to eradicate if they get in to the wrong place. Field bindweed is fast growing and can choke most other vegetation growing near it. It also forms quite large mats which prevent even grass from growing beneath it! Add to its list of faults that it is mildly toxic to grazing animals and it easy to see why it is unwelcome on farms and in gardens.
This plant is sometimes known as "Our Lady's Wine Glass" because of its delicate funnel shaped flower and the tinge of wine colouring in the petals.
