Zantedeschia aethiopica 'Crowborough'

hort.

This is the most resistant Zantedeschia. It can stand negative temperatures outdoors.
I'm not quite sure if it's the 'Crowborough' cultivar on my photos (except the first one), it differs from the typical form
in brownish lower part of petioles, and it's taller, about 1 m with an inflorescence.

Z. aethiopica growing in Nantes (France).	View of a blooming plant.
Planted in the ground in 2002, it prepared to bloom in the end of October, but cold days came and the flowers didn't open.	When it's dug 15 cm below the ground level, the brown petioles aren't visible.
