Did you watch the flowers develop? Many Zantedeschia have inflorescences
that match
your description as the flower matures. For species in section Aestivae,
the entire
spathe turns leaf-green and the spathe furls tightly, and there is often
a whitish patch at the interior base. The next step  is for the flowering
stem to bend downward until the inflorescence touches the ground.

Both ssp. of Z. albomaculata, Z. elliotiana, Z. jucunda, Z. pentlandii,
Z. rehmanii, and Z. valida
comprise this section.

You'd could have a new hort. variety if the green color is there from the
beginning of blooming and persists
throughout the blooming period although some Z. rehmanii come close to

You might want to read these two papers on Zantedeschia. Both have
excellent keys and the latter
has beautiful colored photos as part of the key.
