Abundant tubers late in fall have a rich peppery flavor. Edible leaves and florets. Mashua tubers are high in vitamin C and relatively high in protein for a root crop. Protect in winter. They are fast growing in cool, wet weather and are generally able to out-compete and smother weeds
Tubers range widely in size, from about three inches to more than thirteen inches. Yields can reach almost twenty pounds for plants grown on trellis, but are typically closer to five pounds without. Cooked tubers are usually softer than potato and often taste cabbagey. Leaves can be eaten and taste very similar to mustard greens.Tubers are produced during the short days of fall and are not ready for harvest until mid-November. Protect in early fall for a larger harvest.
