August 10th – Himalayan Balsam is a pain. Lovely to look at, its highly aromatic, metallic-smelling flowers line wetlands, riverbanks and marshes at this time of year. Growing to a couple of meters, it chokes native plants and is considered an invasive species. Sadly, it’s so prolific – this clump was on the banks of the Trent at Shugborough – I don’t think we’ll ever be rid of it.
