Field Bindweed (Convolvulus arvensis)

Field bindweed, also known simply as bindweed, is a persistent and widespread perennial weed that can be challenging to manage in gardens and cultivated areas.

Considerations for Pets

  • The text indicates that bindweed contains cardiac glycosides and alkaloids. While moderate consumption is reportedly harmless for tortoises, caution is advised, and enclosures should be cleared of excessive amounts of bindweed.

Considerations for Children

  • The text mentions the climbing habit of bindweed, with vines that wrap tightly around plants and objects. This could present a tripping hazard if growing in areas frequented by children.
