'Don't know, Mary, about prairie violets. You could order the seeds and try them.

Sherry

Thanks, Sherry, I think I will order the seeds and give them a try. I've read a bit more about how the wild violets are used as a host so will leave a small bed of the ones I want to get rid of alone, with chopped up oak leaves scattered around them for any little cats to hide under, just in case these violets won't act as a host. The wild ones that grow here are so pretty but they fling seeds everywhere.

BTW, I should have provided the correct name for the violets I asked about, Viola pedatifida.

Mary

what fritillaries do you have? I think great spangled and Diana fritillaries use it. I could be wrong about the Dianas.
