Horseradish (Armoracia rusticana) is a large tropical looking plant features large, variably sized 18-24" long, shiny, dark green leaves (resembling Silphium). It is also a perennial vegetable that is grown for its pungent, fleshy roots which are harvested and grated to make sauces. Insignificant, whitish flowers which appear in summer. Beware that this is an extremely vigorous plant that crowds out most weeds and is itself weed-like, with a very spreading growth habit. Best planted and allowed to grow as large isolated clumps, mowing around it generally stops the yearly spread. Included in our "edibles" plant database section.
