BACKGROUND AND ORIGIN OF THE PLANT
The present invention relates to a new and distinct Hosta plant, Hosta 'Wrinkle in Time' hereinafter also
referred to as the new plant or just the cultivar name, 'Wrinkle in Time'. Hosta 'Wrinkle in Time' was
discovered by the inventor as a non-induced,
naturally-occurring, whole-plant mutation in a batch of
field division propagated Hosta 'Pilgrim' (not patented)
at a wholesale
nursery in Zeeland, Mich., USA in the
summer of 2010. The new plant has been asexually
propagated by division at the same nursery in Zeeland, Mich., USA since 2012 and also by careful plant shoot
tip tissue culture with the resultant asexually
propagated plants having retained all the same traits as
the original plant. Hosta 'Wrinkle in Time' is stable
and reproduces true to type in successive generations of
asexual reproduction.
No plants of Hosta 'Wrinkle in Time' have been sold,
under this or any other name, in this country or
anywhere in the world, prior to the filing of this
application, nor has any disclosure of the new plant
been made prior to the filing of this application with
the exception of that which may have been disclosed
within one year of the filing date of this application
and was either derived directly or indirectly from the
inventor.
BRIEF SUMMARY OF THE PLANT
There are over 5,600 registered Hosta cultivars with The American Hosta Society, which is the International
Cultivar Registration Authority for the genus Hosta along with a similar number of unregistered cultivars.
The nearest comparison variety is Hosta 'Pilgrim’, and
the new plant differs by having more undulating foliage,
especially when young.
Other similar hostas include: 'Pilgrim's Progress' (not
patented), 'Academy Subtle Sally' (not patented), 'Allan
P. McConnell' (not patented), 'Angel Feathers' (not
patented), and 'Bob Olson' (not patented). 'Pilgrim's
Progress' has flatter leaves and slightly lustrous
foliage above and below. 'Academy Subtle Sally' has
slightly lustrous adaxial foliage and petioles with
reddish spotting. 'Allan P. McConnell' has slightly
longer and thinner leaves, the leaf center is slightly
more bluish-green, and the margin is more white to
creamy white. 'Angel Feathers' has a more cordate leaf
blade with wider margins, more feathering of the
variegation into the leaf center, and the plant habit is
larger and more upright. 'Bob Olson' has a less
purple-red stippling in the scape, and none of the above
have the undulations of the foliage of the new plant.
Other Hosta cultivars have variegated foliage, but 'Wrinkle in Time' is distinct from the above mentioned
hostas and all other cultivars known to the discoverer
by the following combined traits:
◦1. Compact rounded-mound plant habit with dense
variegated foliage;
◦2. Foliage with wide creamy-yellow becoming
creamy-white margins, green center and minor
intermediate feathered colors between;
◦3. Lavender flowers on green scapes with purple
stippling; and
◦4. Leaves with a longitudinal pinching or indentation.
BRIEF DESCRIPTION OF THE DRAWINGS
The photographs of the new plant demonstrate the overall
appearance of the plant, including the unique traits.
The colors are as accurate as reasonably possible with
color reproductions. Ambient light spectrum,
temperature, source and direction may cause the
appearance of minor variation in color.
FIG. 1 shows a two-year-old plant grown in a full-sun
field with flowers and buds and beginning to develop the
creamy-white margins.
FIG. 2 shows a close-up of a leaf of a two-year-old
plant with undulations.
DETAILED BOTANICAL DESCRIPTION
The following descriptions and color references are
based on the 2001 edition of The Royal Horticultural Society Colour Chart except where common dictionary
terms are used. The new plant, Hosta 'Wrinkle in Time’,
has not been observed under all possible environments.
The phenotype may vary slightly with different
environmental conditions, such as temperature, light,
fertility, moisture and maturity levels, but without any
change in the genotype. The following observations and
size descriptions are of a potted three-year old plant
in a shaded greenhouse in Zeeland, Mich. with
supplemental water and fertilizer.
