Dwarf varieties can be planted in rock gardens, as edgings and as low ground covers. Large clumps of arching leaves, flowers in open or branched clusters. One of the gains in modern hybrids is the length of the growing season, as well as the larger choice of colors. Sword-shaped leaves, bright green. Lily-like flowers at ends of leafless stems standing well above the foliage.
Colors range from yellow to orange to pink to deep maroon red.
Newer colors include lavender and purple. There are few plants that are more persistent, more pest free or tougher. Feed with complete fertilizer spring and midsummer, and divide crowded plants in early spring or late fall.
