Thalia dealbata is a hardy bog plant that flowers in July, August and September.  On top of the narrow powdery blue colored spikes appear rich purple flowers.  It is hardy and will winter over in colder climates, to Zone 5 with no special protection.  Thalia dealbata will grow in sun to part shade in moist soil or water to 6 inches deep.  It can spread to about 24 inches and a height of 2-6'.
