Comfrey - 12 seeds

Symphytum officinale, also known as comfrey, greater comfrey, knitbone, or symphytum, is a perennial plant belonging to the Boraginaceae family. It originates from Europe and Western Asia and is commonly found in fields and scrublands. The plant can reach up to nearly a meter in height and has large, hairy, dark green leaves. Comfrey flowers are dark purple and are grouped in clusters. The roots of the plant are thick and can be light brown or dark brown in color.

The plant has traditionally been used for medicinal purposes, mainly the root and leaves, and is known partly due to its potential medicinal value, but also because it is a very versatile plant. It can be used as a natural fertilizer in the garden, and its leaves can be used as green manure. It is also an attractive plant that can add visual interest to a garden, especially when it blooms from late May to early October.

How to sow Comfrey seeds

Comfrey seeds are sown in seed trays in spring, with March being the ideal time, in a loose substrate that retains moisture.

Some experts suggest that a cold period around 5ºC improves germination, which occurs about a month after sowing under ideal conditions.

Since germination is quite irregular, some seeds will germinate in the expected time, while others may take longer.

Once the plant has two pairs of leaves, it is recommended to plant it outdoors in well-drained, deep soil to allow the development of its thick and deep roots.
