This hybrid cultivar is the
result of a cross between H. 'Gold Regal' × H. 'Wide Brim'. It was registered by
Paul Aden of New York in
1986. The plant grows to a mediums size about 14 inches in height and 40 inches in
width. Its leaves are moderately cupped and corrugated with good
substance. From late June into July, it bears pale lavender
flowers on 24 inch tall scapes followed by viable seeds.
The Hostapedia by Mark Zilis (2009), "....should bear a warning label,
"For Container Use Only". Container-grown specimens can be quite
attractive, but mature garden plants usually look unsightly by
midsummer due to tearing of the white margins."
The New Encyclopedia of Hostas by
Grenfell (2009) states: "Slow to increase. Superb as a young plant but the
edges can split or tear in maturity; nonetheless it remains popular, especially
as a pot plant, because of the strikingly variegated leaves...Particularly wide
and well-defined variegation for a hosta of this size."
An article by Warren I. Pollock in
Hosta Journal (2000 Vol. 31 No. 1) states that, "H. 'Brim
Cup' (Aden - 86)...Many gardeners report this hosta is hard to grow. There is
tearing of the wide gold borders, normal to the green center, as the leaves
emerge during spring growth. This is believed due to the tensile stresses that
develop between the border and center coloring when the leaves develop their
deep bowl shape. I find that heavy fertilization promotes this ugly appearance.
A well grown 'Brim Cup' is a very handsome hosta, well worth experimenting
