A self-pollinated seedling of H. sieblodiana 'Frances Williams', this cultivar was registered by Dr. Kevin Vaughn of Massachusetts in 1977. It forms a large size mound of blue-green foliage that bears lavender flowers in July.

According to The Hostapedia by Mark Zilis (2009), "Kevin Vaughn used the pollen of 'Blue Lace' in his breeding program, resulting in at least two introductions, 'Tarnished' and 'Aqua Velva'."
