I am growing the pink throated form of Zantedeschai aethiopica (
Kiwi Blush) from some years but with very disappointgin result so
far. I got it from an UK friend, where it wa summer growing for him,
but I expected the plant would revert to a winter groing cycle as
normal for my area. The plants instead are stuck on their summer
growing cycle, they appear in late April, no matter of waterings or
temperatures, but they go dormant in summere for excessive heat, so
they don't increase or flower at all. I suppose thus the summer
growing clones don't change cycle even in a warm Mediterranean area?

Angelo,

I find the pink form of Zantedeschia aethopic (sold here under
'Marshmallow' and another name, although as far as I know they are
the same thing) a complete disappointment to me too. While the
straight species (i.e the normal white) flowers very well here and
various times of the year, the pink form rarely ever flowers. I am
lucky if I get a flower or two each year, despite it being in 2
separate areas and treated similarly to the species. It has slowly
started to clump, but not much and it has leaves above the ground far
less than the straight species. I am assuming that my form is
probably the same as yours, just sold under different names in
different countries.

Cheers.
