BACKGROUND OF THE INVENTION
The new cultivar was discovered as an induced mutation
using the known chemical colchicine, of Hosta
hybrid 'Praying Hands' unpatented. 'Hands Up' was
discovered by the inventor,
Marco Fransen, a citizen of
the Netherlands in October of 2008, at a research
facility in Ter Aar, The Netherlands. The intent of the
breeding program was to create new tetraploid Hosta
hyrids with stronger foliage and plant vigor.
Directly after discovery of the tetraploid mutation, the
inventor initiated cultivation in tissue culture, during
October of 2008, in a commercial laboratory in Iribov
Heerhugowaard, the Netherlands. 'Hands Up' was first
propagated in the same commercial laboratory in Iribov
Heerhugowaard, the Netherlands by tissue culture.
Subsequently 'Hands Up' has been reproduced by
micro-propagation and has shown that the unique features
of this cultivar are stable and reproduced true to type
through several generations.
BRIEF SUMMARY OF THE INVENTION
The cultivar 'Hands Up' has not been observed under all
possible environmental conditions. The phenotype may
vary somewhat with variations in environment such as
temperature, day length, and light intensity, without,
however, any variance in genotype.
The following traits have been repeatedly observed and
are determined to be the unique characteristics of 'Hands Up' These characteristics in combination
distinguish 'Hands Up' as a new and distinct Hosta
cultivar:
o
1. Distinctive, upright plant habit.
o
2. Thick foliage.
o
3. Large flowers.
o
4. Vigorous plant.
COMPARISON TO PARENT
Plants of the new cultivar 'Hands Up' are similar to
plants of the parent; Hosta hybrid 'Praying Hands' in most horticultural characteristics, however,
plants of the new cultivar 'Hands Up' are more vigorous
and produce thicker, stronger leaves than the parent
variety. Additionally, the new variety produces larger
flowers than 'Praying Hands'. Leaves of 'Hands Up' have
a wider variegation on the margin than 'Praying Hands'.
COMMERCIAL COMPARISON
The most similar commercial Hosta hybrid variety
available to compare to 'Hands Up' is the parent
variety, as the very strong upright habit is not
commonly found in Hostas.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph in FIG. 1 illustrates in
full color a typical plant of 'Hands Up' grown outdoors.
This plant is approximately 6 months old, shown in a 1
liter pot. The photograph was taken using conventional
techniques and although colors may appear different from
actual colors due to light reflectance it is as accurate
as possible by conventional photographic techniques.
DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made
to The Royal Horticultural Society Colour Chart, 2001,
except where general terms of ordinary dictionary
significance are used. The following observations and
measurements describe 'Hands Up' plants grown in a
commercial nursery in the Netherlands, from February of
2011 through June of 2011. Temperatures were 5° C. to
20° C. at night and 10° C. to 30° C. during the day.
Measurements and numerical values represent averages of
typical plant types. No growth regulators or special
treatments were used.
