Hardiness: fully hardy
Striking, burgundy flower spikes on long slender stems flower continuously from May to September. The attractive, crinkled, rosettes of silver-green foliage are an excellent foil for the flowers, which are also highly attractive to butterflies. A versatile plant that spreads slowly and performs best in a moist border in sun or partial shade, or it can be grown in a pot on the patio. It makes an excellent cut flower, too.
