My friend Sally gave me a division of Eramosa Skies from her garden about five years ago. It's an awesome border plant that grows up to 13 inches tall. It typically begins to bloom at the end of April or first week in May, depending on the weather. Dwarf bearded irises bridge the bloom gap in my garden between the daffodils and tall bearded irises.
In case you wondered, Eramosa is a township in Wellington County, in midwestern Ontario, Canada. Hence the name 'Eramosa Skies.'
