Purchased thru the 2007 Pacific Calla coop. My plants may have the first year blahs as the color is not as bright as the catalog pics, but I am totally confident this will improve with time. All my callas have behaved this way.

A very colorful hot pink Calla Lily with an ivory white throat, plain medium green lance shaped leaves, which grows very easily in bright shady gardens or as a potted plant that can easily be taken indoors during the winter time in Zones 7 and colder.
