Hosta lancifolia produces an excellent ground cover with deep olive green leaves and vigorous vegetative growth. Since this species is of ancient horticultural origin and does not occur in the wild, it has been reduced to cultivar status in horticultural nomenclature as Hosta ‘Lancifolia’ (W. G. Schmid 1991).
