Title: Violets becoming invasive in Prince Edward Island, Canada
Answered by: Barbara Medford and Joe Marcus

QUESTION:

Last Spring I planted several violets and by the end of the Summer they have become an invasion in my garden. I'm afraid that they will get into my lawn and cause a real problem. Any way of getting rid of them permanently before they get out of the flower beds around my house?

ANSWER:

There are a number of different species of the genus Viola native to North America, but we are guessing that what you have is Viola labradorica (alpine violet), since it is native to Prince Edward Island.

The best approach is to let 'em spread!  As wildflowers go, not many are prettier and more endearing than native violets.  A lawn sprinkled with these little twinkling jewels sounds like a bit of heaven to us!  However, removing violets takes perseverance. You must dig out the plants to remove all of the fleshy roots or else they simply resprout.  Remove spent flowers to prevent seeds from maturing and spreading.
