With pretty, bright pink flower spikes and mounds of green foliage, Persicaria Bistorta Hohe Tatra ( also known as knotweed) gives a lovely display in early summer. These eco-friendly perennials grow happily in sun or shade and spread quickly to create a carpet of colour. Like all our pesticide-free perennials, these cottage garden plants are grown organically, so they’re excellent for a bee-friendly garden.
