This well-known hardy, evergreen plant has attractive strap-like leaves and umbels of blue flowers that are borne on long stalks.
They make good cut flowers. Its large rhizomes are easily split. It grows in sun or semi shade making it a good choice for those difficult areas that are in shade for part of the year and in sun for the rest of the year.
Rhizome added to necklaces worn by Xhosa brides to promote child birth.
