Description

This plant is a herbaceous perennial herb with a deep taproot.  It is also grown as an annual and a vegetable.  As a vegetable, it is grown for its fleshy roots that are harvested and grated to make relish and sauces.  

Its vigorous growth habit will allow it to smother out other vegetation, including weeds.  This is particularly true if the plant is not harvested each fall.  Leaving roots in the ground in lieu of harvesting will promote growth in the off months.  

Propagation can be done annually by removing the roots and storing them for planting the following year.

Insects, Diseases and Other Plant Problems:  It can be difficult to eliminate due to its deep taproot.
