This fast growing
classic cultivar consists of a large size (26 inches
high by 63 inches wide) mound of green foliage and
fragrant flowers later in the season. It was
John J. Grullemans who was the owner
of the original
Nursery when it was located in Ohio. 'Royal
Standard' is a hybrid of
which occurred in the early 1960s. At that time
this plant was also granted the
first hosta cultivar
patent by the U.S. Patent Office in 1963. The life of a plant
patent is 17 years so it expired in 1980. It was registered by
The American Hosta Society on his behalf in 1986.
This hosta has
wavy, shiny foliage of a medium green color. The leaves are
slightly corrugated and are very shiny on the bottom. True to
its heritage, it bears fragrant white flowers in abundant
numbers from mid-August into September.
The Hostapedia by Mark Zilis (2009), "Historically, 'Royal Standard'ranks as one of the first American hosta introductions and was
the first to be patented...Over the years, it has been listed
under a variety of other cultivar names, a few invented to avoid
paying patent royalties, others simply mistakes in plant
identification. These names include 'Royal Command', 'White
Knight', 'Hadspen White', 'Liverpool White', 'Sweet
Winifred', and 'Wayside Perfection'.
The New Encyclopedia of Hostas by
Grenfell (2009) states: "Leaves will turn chartreuse when exposed to full
sunlight. Less likely to bloom well in cooler,
wetter regions...Very fragrant, waxy, white flowers
that are far more abundant than those of its H.
An article about H. 'Hoosier Harmony' (originated by
Bob Solberg) by Warren I. Pollock in
Hosta Journal (1996 Vol. 27 No. 1) states that, "I think
this is the best new introduction of 1995...It has all the great characteristics
of 'Royal Standard'. It is a good grower, with big white fragrant flowers, that
will tolerate sunny locations given ample water."
A Photo Essay article by Steve Chamberlain in
Hostta Journal (2010 Vol. 41 No. 1) makes comments about
H. 'Dee's Golden Jewel', "Kevin Walek registered this cross of 'Royal Standard'
and 'Galaxy' in 1996. In maturity, it has turned out to be a very large plant
with a very congested habit. This hosta is an outstanding blue early in the
season, but the leaves turn yellow later, even if there is only brief sun
exposure each day. New leaves emerge blue, giving an unusual two-toned
appearance to a vigorous clump."
In an article in
Hosta Journal (2016 Vol. 47 No 2), the author
described this plant's flowers as having a "Strong" fragrance
compared to other hostas.
This cultivar has been awarded the Royal Horticultural Society's
