Zantedeschia aethiopica 'Crowborough'

A tough, hardy form of the classical florists arum lily. Has wide spathes of pure white flowers held above handsome dark green leaves marked with a swirling pattern of veins. Strong clumps of overlapping leaves form a distinctive feature when flowers are finished. Grows well in deeply prepared soil kept moist in summer. Although this form seems to tolerate less moisture. The crowns must be protected in winter with a mulch. Will also thrive in deep mud in natural ponds where the water will provide adequate frost protection so long as the crown remains submerged below any ice.
