If you have a boggy, damp area in your garden, consider planting carex morrowii. Or turning the outside tap off.

Carex morrowii, also known as Japanese Sedge, is an evergreen ornamental grass that flowers with tiny cream blooms during the springtime. Used to add texture and foliage to gardens, it also thrives in wet conditions, so is ideal if you have a boggy or damp area of the garden. This grass is easy to grow, requiring little on-going maintenance. This makes it a great addition to the garden of the novice or time short gardener. It’s tough enough to cope with the worst of the British weather, asking only to be located in a sunny position to best thrive.
