This gold margined sport of the species was found in
Dr. Fumio Maekawa around 1940 and registered by
The American Hosta Society in 1987. At that time, its name was
'Aureo-marginata' but it was changed by
Schmid (1991) to its current name,
H. montana 'Aureomarginata' to conform with
plant naming conventions of the time.
This large size (27 inches
high by 68 inches wide) plant is known for its upright, vase-shape. The
leaves have deeply impressed veins, are slightly wavy
and faintly corrugated. The bright yellow on the leaf
fades to chartreuse as the season progresses. Very pale
lavender flowers bloom in late July. The flowers are
subtended by whitish
The Hostapedia by
Mark Zilis (2009), this cultivar "...ranks
near the top of any hosta list due to its brightly
colored foliage, large size, and attractive flowers. In
the landscape it makes an impact and can become a focal
point if sited properly."
This beautiful hosta is one
of the earliest types to emerge from the ground in the spring.
To avoid frost damage to the leaves, you may need to give it a
covering when early spring frosts are predicted for your area.
An article by Warren I. Pollock in
Hosta Journal (2000 Vol. 31 No. 1) states that, "H.
montana 'Auroeomarginata' (AHS - 87). With its wide gold border, this large
hosta is a harbinger of spring, but note that because it emerges from the ground
very early it can get nipped by frost."
A Photo Essay article by Steve Chamberlain in
Hosta Journal (2010 Vol. 41 No. 1) makes comments about
H. montana 'Aureomarginata', "The species
H. montana is common on the islands of
Japan. Undoubtedly it has sported to the edge-variegated form numerous times,
and it is likely that not all the forms of H. montana 'Aureomarginata' in
commerce are identical."
