This hardy perennial forms tidy clumps of deep green, strap-like leaves. Spikes of purple flowers appear on spikes in late spring and early summer. Ideal for borders, edging along paths, embankments and containers. Very useful as a landscape plant when mass planted. Grow in a sunny to partly shaded position in moist, well drained soil. Tolerant of frost and coastal conditions.
