Symphytum ssp. This classic permaculture plant grows incredibly deep tap roots, mining rich nutrients from deep below the soil surface. It's a living mulch that 'molts' 3-4 times each season. It's used in traditional medicine and creates a healthful compost tea full of calcium and potassium. It grows up to 70 cm tall, before molting down, and spreads slowly over the years.
