One of our favourite plants, this comes from Brazil, Uruguay and Argentina and is a statuesque sage of marsh and swamp.
In the UK it needs a sheltered border with some moisture but not a waterlogged site. The combination of our winter cold and wet will freeze the roots if the soil is too boggy.
At well over a metre high protection from strong winds is advised along with a thick mulch after dieback.
A little effort and careful sighting pays dividends because it's a gorgeous plant to own. The flowers are small but borne in profusion on many branched stems. The fast growing foliage is wonderfully aromatic attracting pollinators from miles around.
Unlike any other sage, the growth habit is thin and wiry, very similar to Verbena bonariensis. Combine these two with tall grasses for a magical combination. It can also be grown in large pots & tubs.
