The Hostapedia by Mark Zilis (2009), "H. rectifolia 'Aureo-marginata'
= H. rectifolia 'Kinbuchi Tachi'."
H. rectifolia sport from
Japan was registered by
Peter Ruh of Ohio in 2002
with new data in 2018. It forms an
upright, large size mound about 19.5 inches tall and 19 inches wide. The foliage
is dark green but lighter green near the edges with a creamy white marginal
variegation. Its leaves are elliptic, slightly corrugated, moderately cupped,
moderately twisted, moderately folded and slightly shiny on top. The petioles
are also green with a creamy margin. Lavender flowers bloom from mid-August into
September on scapes about 26 inches tall followed by viable seeds.
The registration materials state: "...most leaves
are erect; wide variegation; thin substance..."
Mark Zilis (2009)
adds, "...a vastly underrated Japanese
hosta. It makes a striking mound of foliage that is nearly
upright in character, and its flowering habits are highly
ornamental. The name, however, represents more than one plant."
Mikiko Lockwood in an article on The Hosta Library titled,
A Little About Japanese Hosta Terms defines the term kinbuchi
as gold-edged or yellow edged and the term tachi as upright, 'Tachi Giboshi' or
Seedlings include H. 'Pink Lemonade'.
