Claims
I claim:
1. A new and distinct cultivar of ornamental fern Athyrium plant
named `Crested Surf` as herein described and illustrated.
Description
Botanical classification: Athyrium niponicum.
Variety denomination: `Crested Surf`.
STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(B)(6)
The first disclosure of the claimed plant, in the form of a sale,
was made by Walters Gardens, Inc. on Jul. 8, 2019. Plants for this
sale were obtained from the inventor. Prior to this sale, on Dec.
1, 2018, the plant was first advertised on a website managed by
Walters Gardens, Inc. The plant was also listed in the "Walters
Gardens 19-20 Catalog` published and released on May 29, 2019.
Walters Gardens, Inc. obtained the new plant and all information
about the new plant directly from the inventor. No plants of
Athyrium `Crested Surf` have been sold, in this country or anywhere
in the world, nor has any disclosure of the new plant been made,
more than one year prior the filing date of this application, and
such sale or disclosure within one year was either derived directly
or indirectly from the inventor.
BACKGROUND OF THE INVENTION
The present invention relates to the new and distinct Athyrium
niponicum given the cultivar name `Crested Surf` and developed by
the inventor in a greenhouse at a wholesale perennial nursery in
Zeeland, Mich., USA. Through trials at the same nursery the plant
was referred to by the code 09-124-01. The new plant has been
successfully asexually propagated initially by division in 2015
followed by shoot tip tissue culture at the same nursery in
Zeeland, Mich. Both these asexual propagation systems has been
found to produce stable and identical plants that maintain all the
unique characteristics of the original plant in successive
generations.
BRIEF SUMMARY OF THE INVENTION
Athyrium `Crested Surf` differs from its parents as well as all
other Athyrium known to the applicant. The present invention has
not been evaluated under all possible environmental conditions. The
phenotype may vary with changes to the growing conditions such as
light intensity or duration, nutrient availability, water
availability, etc. without any change to the genotype. The most
similar known Athyrium cultivars known to the inventor are:
Athyrium hybrid `Ocean's Fury` U.S. Plant Pat. No. 20,126, Athyrium
filix-femina `Dre's Dagger` (not patented), Athyrium niponicum `Joy
Ride` (not patented), Athyrium niponicum `Thrill Seeker` (not
patented) and Athyrium niponicum `Apple Court` (not patented).
`Ocean's Fury` has a taller and narrower habit, less creating
branching, smaller pinnules and with less reddish stems. `Dre's
Dagger` has finer textured foliage, narrower leaf blades, paler
green leaf color without the wine-colored petiole and pinna and
pinnule midribs, and without the light green variegation near the
middle of the pinna and pinnules. `Joy Ride` has more compact
habit, more tasseled with less red on the stems. `Thrill Seeker`
has more cresting with less red in the stems and less upright
habit. `Apple Court` has less vigor and less upright with pinnae
that are broader. The female and male parent was shorter than
`Crested Surf`.
The new plant, `Crested Surf`, is unique from all ferns known to
the inventor by the following combined traits: 1. Stiff upright
habit; 2. Foliage serrate, finely-textured, broadly-lanceolate,
bipinnately compound with alternating deep green and light green
portions of the pinnae and pinnules; 3. Pinnae and pinnules with
compound crested apices; 4. Petioles and midribs with wine
coloration.
BRIEF DESCRIPTION OF THE DRAWINGS
The color drawings illustrate the overall characteristics of the
new plant and demonstrate the overall appearance of the new plant
including the unique traits as a three-year-old plant growing in a
shaded trial garden in Zeeland, Mich. with supplemental water and
fertilizer as needed. The colors are as true as reasonably possible
given the technology available. The colors are as accurate as
reasonably possible with color reproductions. Ambient light,
spectrum, temperature, source, duration and direction may cause
minor variation in appearance.
FIG. 1 shows the new plant grown in a shaded trial garden.
FIG. 2 shows a close-up of the top of the foliage and apical
cresting.
FIG. 3 shows a close-up of the top of the foliage and marginal
cresting.
FIG. 4 shows a close-up of the back of the foliage of the new plant
with sporangium and cresting.
DETAILED DESCRIPTION OF THE INVENTION
The following detailed description is based on a three-year-old
plant growing in a shaded trial garden in Zeeland, Mich., USA.
Environmental conditions for the growing season daytime
temperatures range between 12-30.degree. C., and night temperatures

usage, color references are according to The Royal Horticultural
Society Colour Chart, 2015 edition. Parentage: Female or egg parent
is an unnamed proprietary selection of Athyrium niponicum (not
patented); male or sperm parent is the same unnamed proprietary
selection of Athyrium niponicum (not patented); Asexual
