A sport of H. 'Undulata
Univittata' was registered by
Eldren Minks of Minnesota
in 1974. It forms a large size (19 inches high) mound with very narrow leaves
and pale lavender flowers in late July. The white leaf center is
about 1/3 the width of the parent cultivar.
Similar cultivars include H. 'Foxfire Viper' and H. 'Unitalis'.
