a week of weeds - Pentaglottis sempervirens

14th May 2022

Green alkanet is a relative of comfrey: it is a garden perennial native to Southern Europe which has naturalised in woods and grassy places, especially on alkaline soils. It self-seeds freely and the taproots regenerate strongly so it can be hard to remove. However it is an attractive plant when in flower, and like comfrey it can be added to compost as a nitrogen booster.
