A hybrid of H. 'Dorothy Benedict' × H. montana, this cultivar was originated by Dr. Ralph (Herb) Benedict of Michigan and registered on his behalf by Kevin Walek (Hosta Registrar) in 2009. It forms an upright, vase shaped, large size mound about 20 inches high and 50 inches wide. The dark green leaves are heavily streaked and mottled with yellow and creamy white specks. Its leaves are moderately corrugated, ovate and slightly wavy with thick substance. It bears lavender flowers in July.

According to The Hostapedia by Mark Zilis (2009), "Over the last twenty-five years or so, very few hostas have impressed me as much as the Benedicts' specimen of 'Outrageous'...The variegation pattern varied considerably from leaf to leaf, but I think that only added to its character. I'm not sure if I'll ever see another mature clump of 'Outrageous', but the memory of the Benedicts' plant will remain with me for many years to come."
