Lily of the Valley.  A good selection of this stalwart species with a yellow margin to the leaves and said leaves are larger than average as well.  Typical scented white flowers.  There are numerous spellings of the cultivar name but since this is an American introduction, we can only assume this is correct.  Sad.

A lovely gold leafed sport of 'Cream da Mint' that Rick Sawyer found in his Fernwood Nursery in Maine. This truly glows particularly in spring when the gold coloration is at its best. The larger than usual white scented flowers are a fine accompaniment. Slower spreading than many selections.
