Common / True Comfrey

Description
True or Common Comfrey (Symphytum officinale) is a hardy perennial shrub native to Europe and Asia and is highly valued for permaculture/subsistence gardens.

Substantial foliage forms approximately 90 days after transplanting seedlings. Perennial.

Planting Details
One of the most important things to know about comfrey cultivation is that the seeds must be buried. Unlike many seeds that are flexible so long as there is water, comfrey seems to not germinate well or at all with light exposure.
