This cultivar has all the benefits of comfrey, except it does not set seed and therefore doesn't have the aggressive (or even invasive) properties of the usual comfreys. It is easy to grow and can be propagated by simply digging up some of its roots and planting those roots somewhere else.

It is a dynamic nutrient accumulator and is an excellent source of potassium. We grow it here and there and when it's at its peak, we cut it down and mulch our tomatoes and other vegetables with the leaves. It quickly grows back so we can use it this way numerous times each year.

It can be difficult to grow in high heat and bright sun. We have had the best results growing it in places where it receives morning sun but afternoon shade. It doesn't seem to mind dry conditions, it just doesn't like the heat.
