Color Spires® Steel Blue was introduced 2007 or 2008 and I planted 2 plants of it in one of my flowerbeds. I don't remember how many years it lasted.
In 2008 or 2009, I bought a third plant of Color Spires® Steel Blue and planted it into a container that sat on our patio and it survived through at least the 2011 season if not more.
Color Spires® Steel Blue hasn't been available for years.
