This slow growing cultivar is an open-pollinated seedling of a hybrid plant ('Dorothy Benedict' × H. montana macrophylla). It was registered in 2001 by Beverly and Dave Stegeman of Indiana. The plant grows to a height of about 16 inches and a width of 48 inches with leaves that are broadly ovate, heavily corrugated and have thick substance. Very pale lavender flowers bloom in dense clusters starting in late June.

According to The Hostapedia by Mark Zilis (2009), "My listed measurements from a less-than-mature specimen are already larger than the registration dimensions. Regardless of size, 'Skylight' offers very thick, slug resistant foliage in an incredibly blue color and is worth including in any collection."
