Nelumbo `Nanzhou Xuefeng`
Abstract
A new and distinct cultivar of Nelumbo plant named `NANZHAO
XUEFENG` is disclosed, characterized by petals are mainly white
with red-purple outer tips, and yellow bases. Flowers have a
distinctly hemispherical form, composed of a double whorl of outer
petals and a distinctive mounded center made up of a large number
of whorled petals and petaloids. The new variety is useful as both

Claims
What is claimed is:
1. A new and distinct cultivar of Nelumbo plant named `NANZHAO
XUEFENG` as herein illustrated and described.
Description
Latin name of the genus and species: Nelumbo nucifera.
Variety denomination: `NANZHAO XUEFENG`.
BACKGROUND OF THE INVENTION
The new cultivar, Nelumbo `NANZHAO XUEFENG`, is the product of a
planned breeding program. The new variety originated from a cross
pollination of the unpatented, seed parent, Nelumbo `Yuluo Huatai`
with the pollen parent the unpatented Nelumbo `Juwuba`. The cross
pollination was made during July of 2018 in in Nanjing, Jiangsu
province, China at a research nursery. The new cultivar `NANZHAO
XUEFENG` was selected in June of 2019 at the same location.
Asexual reproduction of the new cultivar `NANZHAO XUEFENG` was
first performed by root division in in Jiangsu province, China at a
research nursery during April of 2020. Nelumbo `NANZHAO XUEFENG`
has since produced multiple generations and has shown that the
unique features of this cultivar are stable and reproduced true to
type.
SUMMARY OF THE INVENTION
The cultivar `NANZHAO XUEFENG` 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 `NANZHAO XUEFENG`.
These characteristics in combination distinguish `NANZHAO XUEFENG`
as a new and distinct Nelumbo cultivar: 1. Fully double-whorled
outer petals. 2. Multi-colored flower composed of a primarily white
petal, red-purple apex, and yellow base. 3. Mounded-whorl formation
of central petals forming a hemispherical flower form. 4. Flowering
occurring from mid-June to late August. 5. Individual lowers last 6
to 7 days on plant.
PARENTAL COMPARISON
Plants of the new cultivar `NANZHAO XUEFENG` are similar to plants
of the seed parent in most horticultural characteristics. However,
plants of the new cultivar `NANZHAO XUEFENG` differ in the
following: 1. `NANZHAO XUEFENG` produces more petals per flower
than the seed parent. 2. Flower color of `NANZHAO XUEFENG` is a
deeper red-purple at the tip, and a paler yellow base than the
flower color of the seed parent. 3. Flower form of `NANZHAO
XUEFENG` is hemispherical, with a strong, mounded center; the
flower form of the seed parent is convex. 4. `NANZHAO XUEFENG`
produces larger flowers than the seed parent. 5. `NANZHAO XUEFENG`
has a longer flowering period than the seed parent. 6. `NANZHAO
XUEFENG` sets a scant amount of seed; the seed parent sets a
moderate amount of seed.
Plants of the new cultivar `NANZHAO XUEFENG` are similar to the
pollen parent in most horticultural characteristics. However,
plants of the new cultivar `NANZHAO XUEFENG` differ in the
following: 1. `NANZHAO XUEFENG` produces more petals per flower
than the pollen parent. 2. Flower color of `NANZHAO XUEFENG` is a
deeper red-purple at the tip, and a paler yellow base than the
flower color of the pollen parent. 3. `NANZHAO XUEFENG` produces
larger flowers than the pollen parent. 4. `NANZHAO XUEFENG` has a
higher number of stamens than the pollen parent.
COMMERCIAL COMPARISON
The new cultivar `NANZHAO XUEFENG` can be compared to the
unpatented commercial variety Nelumbo `Zhufeng Cuiying`. Plants of
the new cultivar `NANZHAO XUEFENG` differ in the following: 1.
Flowers of `NANZHAO XUEFENG` produce more petals than flowers of
`Zhufeng Cuiying`. 2. Flower colors of `NANZHAO XUEFENG` are white,
red-purple, and yellow; flower colors of this comparator are
green-white and yellow. 3. Flower form of `NANZHAO XUEFENG` is
hemispherical; flower form of `Zhufeng Cuiying` is flattened. 4.
`NANZHAO XUEFENG` has a partially vesiculated carpel, while this
comparator has a fully petaloid carpel. 5. Flower bud shape of
`NANZHAO XUEFENG` is broad oval; flower bud shape of this
comparator is oval.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate in full color typical
plants of `NANZHAO XUEFENG` grown outdoors, in a pond, in Jiangsu
province, China. The photographs were taken using conventional
techniques and equipment. While the colors in these photographs may
display variances of color as compared to the living cultivar, due
to LRV (light reflectance value), they are as accurate as possible
using conventional photographic techniques. Colors in the
photographs may appear to differ slightly from the color values
cited in the botanical description, which accurately describe the
colors of the new Nelumbo plant. Temperatures ranged from
approximately 13.degree. C. to 28.degree. C. night and about
16.degree. C. to 34.degree. C. during the day. No artificial light,
photoperiodic treatments or chemical treatments were given to the
plants.

Nelumbo `NANZHAO XUEFENG` at approximately 1 year of age.
FIG. 2 illustrates in full color a typical flower bud of Nelumbo
`NANZHAO XUEFENG`.
FIG. 3 illustrates in full color typical fully open flower of
Nelumbo `NANZHAO XUEFENG`.
