If I go out looking for plants in flower now, purple loosestrife (Lythrum salicaria) seems hard to avoid. Since it’s a water-loving plant, and this is the middle of August and la grande chaleur, that seems surprising. But there are streams, deep ditches that collect moisture seeping from the fields, and springs, and reservoirs like this one in my village.
I feel I’m always going on about plants adapted to dry conditions here, but the truth is that each plant has its niche, and niches by definition are not characteristic of the whole.
The origins of the English name are interesting – and for this I rely totally, as I often do, on Geoffrey Grigson’s Dictionary of English Plant Names. The name was coined in 1548 by one of the first and greatest English botanists, William Turner, who took the yellow loosestrife (Lysimachia vulgaris) and purple to be the same plant. He understood the word lusimakheios, used by the Greek herbalist and physician Dioscorides to mean ‘deliverance from strife.’ The Roman Pliny described the herb as being so powerful ‘that if placed on the yoke of inharmonious oxen it will restrain their quarrelling.’
As someone who will go to any lengths to avoid an argument, this appeals to me. However, I have yet to test it with friends, neighbours or indeed oxen. I think a good way to avoid strife is to remember that like plants, humans have their preferences and their niches and their own way of seeing things. I don’t take this too far – like the great Nye Bevan I believe that voting Tory is just wrong.
