Abstract
Disclosed herein is a new and distinct variety of Viola cornuta,
named `Sunviolalemo`. This new variety has a spreading growth habit
with long prostrate stems. This Viola plant has many branches, and
a great profusion of blooms with the entire plant remaining in
bloom for a considerable period of time. The plant displays dense
green foliage, forms single medium-sized yellow flowers with some
gradation of color intensity and some purple striping that are

Claims
It is claimed:
1. A new and distinct variety of Viola cornuta plant named
`Sunviolalema`, substantially as herein illustrated and described.
Description
Botanical classification/commercial classification: Viola
cornuta/Viola Plant.
Varietal denomination: cv. Sunviolalemo.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct variety of
Viola cornuta named `Sunviolalemo` that originated from the
crossing Viola hybrid variety named `9V-29a` as the female parent
and a variety named `Violetto Nive` as the male parent.
In April 2000, crossing of `9V-29a` as the female parent and
`Violetto Nive` as the pollen parent was conducted at Yokaich-shi,
Shiga, Japan. In May 2000, some seeds were obtained. In August
2000, the seeds from the cross were sown and 20 seedling were
obtained. Three of the seedlings were selected in view of their
spreading growth habit, medium flower size and yellow petal color.
Those seedlings were propagated by the use of cuttings and were
grown in pots, and then a plant trial was carried out beginning in
October 2001, at Yokaichi-shi, Shiga, Japan. The botanical
characteristics of the plant were then examined, using a parent
variety, `Violetto Nive` and a similar variety, `Alpine Summer`,
for comparison. As a result, one seedling was selected and it was
concluded that this Viola plant is distinguishable from any other
variety, whose existence is known to us, and is uniform and stable
in its characteristics. The new variety of Viola plant was named
`Sunviolalemo`.
The female parent `9V-29a` (not patented in the U.S.) is a strain
from our breeding lines grown at Yokaichi-shi, Shiga, Japan, having
a spreading growth habit with prostrate stems. It has larger-sized
flowers than the new variety `Sunviolalemo`, and the petals are
white in coloration.
The pollen parent `Violetto Nive` is a commercial cultivar.
`Violetto Nive` (not patented in the U.S.) has a spreading growth
habit with prostrate stems. It has smaller-sized flowers than the
new variety `Sunviolalemo`, and the petals are white in
coloration.
In the following description, the color information is in
accordance with The R.H.S. Colour Chart of The Royal Horticultural
Society, London, England.
SUMMARY OF THE INVENTION
This new variety is unlike any Viola cornuta plant that is
commercially available as evidenced by the following unique
combinations of characteristics. 1. Spreading growth habit having
long prostrate stems and many branches. 2. A great profusion of
blooms with the entire plant remaining in bloom for a considerable
period of time. 3. Single, medium-sized yellow flowers having some
gradation of color intensity that are borne on long peduncles.
The new variety `Sunviolalemo` differs from the similar variety
`Violetto Nive` (not patented in the U.S.) in the following
respects. 1. The stem length of `Sunviolalemo` is longer than that
of `Violetto Nive`. 2. `Sunviolalemo` has long-oblong leaves. Those
of `Violetto Nive` are lanceolate. 3. The peduncle length of
`Sunviolalemo` is longer than that of `Violetto Nive`. 4. The
flower of `Sunviolalemo` is larger than that of `Violetto Nive`. 5.
The flowers of `Sunviolalemo` and `Violetto Nive` differ in petal
color. `Sunviolalemo` has yellow flowers with some gradation of
color intensity. Those of `Violetto Nive` are White. 6. The
flowering time of `Sunviolalemo` is earlier than that of `Violetto
Nive`.
The new variety `Sunviolalemo` differs from the similar variety
`Alpine Summer` (not patented in the U.S.) in the following
respects. 1. The stem length of `Sunviolalemo` is longer than that
of `Alpine Summer`. 2. `Sunviolalemo` has long-oblong leaves. Those
of `Alpine Summer` are lanceolate. 3. The peduncle length of
`Sunviolalemo` is longer than that of `Alpine Summer`. 4. The
flowers of `Sunviolalemo` are larger than those of `Alpine Summer`.
5. The flowers of `Sunviolalemo` and `Alpine Summer` differ in
petal color. `Sunviolalemo` has yellow flowers with some gradation
of color intensity. Those of `Alpine Summer` are bi-colored, the
upper petal is violet, lateral and lower petals are yellow with
dark purple vein. 6. Flowering time of `Sunviolalemo` is earlier
than that of `Alpine Summer`.
The new variety of Viola plant `Sunviolalemo` was asexually
reproduced by the use of cuttings at Yokaichi-shi, Shiga, Japan,
and the homogeneity and stability thereof were confirmed.
The instant plant retains its distinctive characteristics and
reproduces true to type in successive generations.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs show, as nearly true as it is
reasonably possible to make the same in color illustrations of this
character, typically specimens of the new cultivar. The plants had
been reproduced by the use of cuttings and were photographed during
May 2002 while growing outdoors in 24 cm pots at an age of
approximately 7 months at Yokaichi-shi, Shiga, Japan.
FIG. 1 illustrates an entire flowering plant of the new variety
while growing in a pot.
FIG. 2 illustrates a close view of the blossoms of the new
variety.
