Zantedeschia aethiopica, [arum lily] is a south african native plant , so should be no problem, Derek.

The common white Arum Lily (Zantedeschia aethiopica) is something of a bog plant, though it likes drier conditions during hot summers, when it usually goes dormant. The colored-bloom species (Z. elliotiana, Z. rehmannii, and their hybrids) need better drainage and warmer winters than the white one.

that probably means as the flower dies off the colour fades.

Yes, I've never heard of the plant producing paler flowers as it gets older

do you mean Arum or the bog plant also called zandeneschia?
Arum tend to be woodlanders and the corms can be planted about 2-3inches deep in good leafmould/littered soil.
The Zandeneschia I think prefer moister conditions [seen them in bog gardens and shallow ponds] and full sun. they come in a range of colours and yes you can plant them mixed together.
