Field Guide to Hostas by Mark Zilis (2014),
"The powdery blue foliage of 'Flemish Sky' ranks
among the best."
The New Encyclopedia of Hostas by
Grenfell (2009) states: "Best grown in a container set in front of a red
brick wall for color contrast and where the
exquisite beauty of the leaves can be seen close
up...The leaves appear almost pale gray due to the
exceptionally thick pruinose coating, especially
heavy on the reverse which, due to the leaf shape,
is often visible. Leaf tip is very long."
