This species is noted for its
large sized (30 inches high), vase shaped mounds of cupped blue-green foliage.
The leaves are broadly ovate shaped, moderately corrugated and
have thick substance. It has very
tall (about 6 feet high) flower scapes with pale lavender blooms in late July to
mid-August.
According to
The Hosta Handbook by
Mark Zilis (2000), "It has proven to be an outstanding, "impact" plant
in the shade gardens throughout the U.S. Hosta nigrescens
makes an excellent background plant and can be a magnificent
focal point of an island bed."
