Gardeners' Notes:

Neutral Baa On Sep 10, 2001, Baa wrote:

This is the best species for all your liquid compost making.

Widely naturalised in Europe, this is a large perennial covered with stiff hairs. Has broad lance shaped, mid green leaves upto 10 inches long. Bears drooping cymes of usually blue, tubular, small flowers.

Flowers April - June

Spreads to over 4ft and is difficult to get rid of as the tap root can extend over ten feet on mature plants. Likes moist, slightly fertile soil in partial shade although will tolerate sun.

Steep leaves in water until decayed for liquid fertilizer and then dialute to 1 part comfrey liquer to 20 parts water.
