Strong growing perennial. Flowering in Spring/Summer. Best in a sunny site, hardy to dry and cold. Kniphofia might have had a better lot in the life of NZ gardens if we called them by some of their other common names. Not all kniphofia are the same - there are tall ones, short ones, yellows, bicolours, deciduous, evergreen and finer foliaged options. Dont overlook them for late summer colour.
