Top choice for butterflies, an absolute magnet, flowering for more than 6 months of the year, very few plants can compete with this for long season flowering. The flowers are a lovely violet colour, in spikes from a mound of foliage. Caring for it is simple and as follows. When flowering is diminishing (which seems to be never) cut back foliage, a bit like lavender, to green shoots. The lower down this is done, the less woody the stems will become and the more compact and green the plant will be.
