This highly sought after sweetly-scented Wallflower goes back many years and produces the most stunning 2cm deep blood-red velvety flowers over a long period of time from late Winter/early Spring. Dead-head regularly to encourage more flowers. Once flowering has finished, trim back by around 1/3 to encourage new, compact growth. Full sun and well-drained soil. 40cm x 20cm approximately.
