This
H. 'Tardiana' type host has
dark blue-green foliage of heavy substance. It was registered by
Paul Aden for
English hybridizer,
Eric Smith
in 1976. It has pure white flowers that appear in July to
early August.
According to
The Hosta Handbook by
Mark Zilis (2000), it was formerly known as 'TF
2 X 2" and, at one time, was also known as H. 'Halo'
which is now a different cultivar.
The Hostapedia by Mark Zilis
(2009), says that "...'Blue Moon' has long been one of the
most popular of the Tardianas. The thick, heart-shaped, blue-green
foliage sets the standard for small-sized, blue-green hostas. It has
also proven to be a good breeding plant, both as a pod and pollen
parent."
