Unfortunately, this is one of the day lilies that did not survive our New Hampshire winter of 2007 - 2008. We ordered other day lilies from the same vendor in a 'collection', and about 60% of the collection did not survive.

We have heard from other gardeners in the area that the 'Ruffled Ruby' is a most viable plant for both our soil and our Zone, so we will be attempting to grow it one more time.
