Perennial, hardy in zones 3-8, common comfrey has been used for centuries. It has purple, rose or white flowers. The leaves are traditionally used as a topical to treat wounds and reduce pain in cuts and scratches. I have used the dried leaves as a bath tea to soothe skin tears.
Comfrey is also an excellent plant for increasing nitrogen in your soil, but it is also highly invasive and difficult to eliminate once established in your garden. Treat it like mint, something that must be continually managed.
Minimum of 10 seeds per packet.
