My aunt in Ohio, z5, loves callas. Every year I get a few for the patio or
garden. I've had more cultivars than I can remember. The ones that I can
remember are Giant Spotted (from Plant Delights), Zwartzwalder, Black
Star and
Flame (from Brent and Becky's) and many a mix of other colors from local
retailers. They have nearly all survived the winters in the open ground 10'
to
30' from the house. They bloom reliably each year.

A couple have gone so far as to reseed. I took a photo if anyone is
interested.
There are a few varieties that have disappeared over time but I don't
remember
what they are as I am not there to see all of them in bloom to know their
colors. I only know a few key placements and ones that still have labels
(that
the family kids have pulled out).

I am pretty sure that the lighter purples are not there.
As far as a yellow variety of Z. aethiopica and am not sure. There are some
really large yellow callas that are the same size of aethiopica but I do
believe they are a hybrid.
