It survived the winter in zone 6b/7a with one leaf.
2010
In 2009 I bought it as Arum maculatum, later I bought another one as Arum italicum. Both of them are the identical, the photos taken in 2010 show both specimens.
The new bought one woke up in April. It grew in a shady place.
The old one in April looked so. It grew in a sunny place.
This is the new one. The last leaf was plain green, without the lighter fields.
2011
In 2011 both plants grew in the same place and they woke up in February.

This plant died one winter, its leaves looked more narrow and longer.
