Q.Ribbon grass
Is it difficult to start ribbon grass from seed?
Or, where can I purchase plants in the Brainerd / Walker / Longville MN area?

It is best to sow Ribbon grass seeds outdoors.
They can be sown either before the first frost of winter or at the start of spring. Once sown lightly cover the ribbon grass seed. For best results grow ribbon grasses in a sunny part of the garden; it is also able to grow in lightly shaded areas. Ribbon grass thrives in a rich and moist soil.
