This non-registered Tardiana-type seedling was introduced by Dr. Ralph (Herb) Benedict of Michigan in 1999. According to The Hostapedia by Mark Zilis (2009), "As 'Blue Pebbles' matures, the leaf blade broadens to a heart shape and the corrugation becomes more intense."

It forms a medium size (14 inches high) mound and displays near white flowers in late July.
