This is the non-spotted Hercules, which I bought from Kartuz, which in turn bought theirs from Western Hills many years ago.

It bloomed for the first time in Feb 2008. Flower not very big but it is a young plant. Planted inground, partial sun. Has not gone dormant in the 2 years I've grown it.

Neutral Kell On Feb 5, 2008, Kell from Northern California, CA (Zone 9b) wrote:

This is the cultivar Strybing Arboretum in San Francisco is growing and selling that originally came from Western Hills Nursery in Occidental, CA. It is a huge variety with great white spots. There is also a nonspotted one with the same name that also came from Western Hills Nursery years ago to add to the confusion. The Strybing calls it Zantedeschia "Hercules" though many sources call it Zantedeschia aethiopica "Hercules".

In warmer areas it will bloom year round.
