Field bindweed is found in a wide variety of lowland habitats including verges, waste tips, and disturbed and arable ground.

Could be Confused with…
Field bindweed may be confused with black bindweed as young plants. Size is a good indicator, as Black Bindweed is much larger.
The main difference is in the cotyledons*; black bindweed has long cotyledons with short stalks, while field bindweed has oval cotyledons, notched at the tip.
Common sorrel has similarly shaped leaves but Sorrel grows in a rosette rather than as a vine and sorrel flowers look very different.
*A cotyledon is part of the embryo within the seed of a plant. Often when the seed germinates the cotyledon may become the first leaves of the seedling. Botanists use the number of cotyledons present in the seed of a plant as a means of classification.
Although there are references to it being eaten in the past, Bindweed contains several alkaloids which are toxic for mice, including pseudotropine, and lesser amounts of tropine, tropinone, and meso-cuscohygrine.
We therefore do not consider it edible!
