Position: Well drained, fertile soil in full sun or partial shade. Ours is in a flower bed that gets sun for most of the day - mid morning 'til early evening and it seems to be fine.
Flowers: Late spring - late summer.
Dimensions: 60cm high x 45cm spread.
Habit: Perrennial herb. The stems are very thin with small flower heads and are prone to leaning over and disappearing into neighbouring plants. Some experts say that the flowers are too small compared to the amount of foliage and I have to say that I'm a bit disappointed with it on the whole.
Care: Water well and leave it alone. I dead head all the spent flowers.
Pruning: Not required. Although I tend to remove any dry and dead foliage.
Propagation: Division in spring or seeds in autumn.
Distribution: Europe, Asia, New Zealand, North/South America and Africa.
