Gardening Q & A

Today’s Common Gardening Questions…Answered!

Why don’t you carry Forget-Me-Not seeds and plants anymore?

Starting last year, the common Forget-Me-Not (Myosotis sylvatica) has been absent from Wisconsin garden centers. That’s because it has been classified as “restricted” invasive weed by the Wisconsin Department of Natural Resources, effective May 1, 2015. Plants that were already in the state before that time can still be moved or planted until May 1, 2018. After that date, transporting, transplanting, and sales will be prohibited by law. You don’t have to remove “restricted” plants from your garden, but purposeful propagation is not allowed.

Plants are classed as ‘Invasive’ when they spread in the environment and cause environmental and or economic harm. This is different than ‘aggressive’, which is when a plant spreads rapidly in the garden. For a legal alternative, try seeds of Chinese Forget-Me-Not (Cynoglossum amabile). This is summer-blooming annual with the same blue flowers. We have the variety “Firmament” available as seed from Seed Savers. To plant, simply sprinkle the seeds on top of the soil where you want them to grow!
