Costus are easilly distinguished from other commonly cultivated gingers because the leaves spiral around the main stem like a circular stairway. In fact they are called Spiral Gingers. The Costus species are rich and varied in form, flower and growing conditions. There are short mounding forms, spreading forms and upright forms.
