Grown primarily for its attractive foliage, variegated sweet flag is a rush with grass-like leaves striped white and green, which emit a sweet scent when bruised. Insignificant tiny spikes of yellow-green flowers in spring give way to inedible red berries in the summer. The plant forms a tuft about one square foot in size, spreading by rhizomes. It is a semi-evergreen and marginal aquatic plant, thriving in wet soil in full sun or partial shade such as the edge of ponds or bogs.
