This seedling of H. ventricosa was introduced in the 1960s and  registered in 1976 by Larry Englerth of Michigan. This medium size (16 inches high) plant has leaves with a slightly rippled margin and distinct, long tip. The semi-bell-shaped flowers are bright purple and open from mid-July into August. It does not form viable seeds.

According to The Hostapedia by Mark Zilis (2009), "...'Little Blue' is not little and it's not blue, but it does make a symmetrical mound of shiny, dark green foliage with an outstanding show of purple flowers in July...a triploid."
