The Hostapedia by Mark Zilis (2009), "...published as a sport of
'Jade Scepter' (Eisel 1989), but sent to
the registrar as a sport of
'Golden Tiara'; from
tissue culture ; after observations since
1988, 'Gold Edger' the more likely mother plant."
Is that confusing or what?
This cultivar which was
registered by Mark Zilis of Illinois in 1988, forms a mound about 8 inches
high with a spread of 17 inches. The foliage is heavily twisted,
corrugated along some veins and of thin substance. Its lavender
flowers bloom in July.
Mark Zilis (2000)
continues, "Unlike many other
white-centered cultivars, it has a fast growth rate...a bit of a
fuss has been raised over the years about whether or not 'Royal
Tiara' is truly a member of the "Tiara family", i.e. related to
'Golden Tiara'...I now believe that it came out 'Gold Edger',
another plant my nursery was propagating at the time."
The New Encyclopedia of Hostas by
Grenfell (2009) states in its Hosta Hybrids for Connoisseurs chapter: "More
vigorous than would be expected of a hosta with such twisted leaves."
