This is a high maintenance plant that will require regular care and upkeep, and should be cut back in late fall in preparation for winter.

Gardeners should be aware of the following characteristic(s) that may warrant special consideration;

Planting & Growing

Comfrey will grow to be about 18 inches tall at maturity, with a spread of 24 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 20 inches apart. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 10 years.

This plant performs well in both full sun and full shade. It is very adaptable to both dry and moist locations, and should do just fine under typical garden conditions. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. This species is not originally from North America, and parts of it are known to be toxic to humans and animals, so care should be exercised in planting it around children and pets. It can be propagated by division.
