This hybrid cultivar from Paul Aden of New York was registered in 1976 as a hybrid of H. 'Aden No. 270' × H. 'Aden No. 275'. It grows to large size about 18 inches in height with a 40 inch spread. The base leaf color is chartreuse but they are a heavily streaked and slightly corrugated. It bears pale lavender flowers from late July into August followed by viable seeds.

According to The Hostapedia by Mark Zilis (2009), "Paul Aden utilized 'High Fat Cream' extensively in his breeding program in the 1970s...The true form of 'High Fat Cream', however, has become nearly extinct. A few hybridizers have managed to keep at least part of their specimens true-to-type, but its propensity to sport to more stable forms makes that difficult."

The New Encyclopedia of Hostas by Diana Grenfell (2009) states: "Slow to increase. Was a very popular breeding plant but since the 1980s has been extremely rare."
