This is an introduction by
of Savory's Gardens in Minnesota who registered it in 1977 as a seedling of an unknown
Japanese hybrid. As the name implies, it forms a
giant size mound up
to 30 inches high and over 8 feet wide. The leaves are slightly
rippled, moderately corrugated and are slightly shiny. Funnel
shaped, pale lavender flowers bloom in late June.
