Oxeye daisy reproduces by spreading rhizomes and seed. An escaped ornamental, it can often be found as an contaminate in wildflower seed mixes.

It is an escaped ornamental that was first recorded in the US in 1838. Since then it has become widely spread and can be found in all 50 states.

Oxeye daisy can be easily controlled by pulling young plants or by treating with herbicide.
