Figwort is a very common plant in the UK but you’d be forgiven for not knowing it as it is very discreet, despite growing up to be 4-5 feet tall. It prefers shady and slightly damp places such as woodland edges, hedgerows etc where it begins to show in spring, growing on until flowering in July/august. Its stems are tall and square whilst the flowers are quite few and far between, consisting of two lips, the tips of the upper lips being tinged with purple/red, really beautiful when you get close in. The flowers give way to tiny fig like seed pods.
