Origin unknown.
Parentage E. derenbergii x E. pulvinata. / E. 데렌베르기 x E. 풀비나타
First described by E. Walther as Echeveria ‘Haageana’, 1933, renamed and redescribed by J. van Keppel in Nat. Cact.& Succ. Journal 21: 55. 1966,.
A hybrid by Charles Uhl with the same parentage is circulating under the name Echeveria 'Powdered Sugar', a name probably never validly published. In any case the name E. 'Graessneri' has priority.
