Claims
It is claimed:
1. A new and distinct cultivar of Kalanchoe plant named `Monroe`,
as illustrated and described.
Description
Botanical classification/cultivar designation: Kalanchoe
blossfeldiana cultivar Monroe.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of
Kalanchoe plant, botanically known as Kalanchoe blossfeldiana, and
hereinafter referred to by the name `Monroe`.
The new Kalanchoe is a product of a planned breeding program
conducted by the Inventor in De Lier, The Netherlands. The
objective of the breeding program is to create new Kalanchoes with
multi-petalled flowers.
The new Kalanchoe originated from a cross-pollination made by the
Inventor in November, 1999, of the Kalanchoe cultivar Leonardo,
disclosed in U.S. Plant Pat. No. 13,365, as the female, or seed,
parent with the Kalanchoe cultivar Pablo, disclosed in U.S. Plant
Pat. No. 11,653, as the male, or pollen, parent. The new Kalanchoe
was selected by the Inventor in a controlled environment from the
resultant progeny of the cross-pollination on the basis of its
multi-petalled flowers.
Asexual reproduction of the new Kalanchoe by terminal vegetative
cuttings taken at De Lier, The Netherlands, since 2000 has shown
that the unique features of this new Kalanchoe are stable and
reproduced true to type in successive generations.
BRIEF SUMMARY OF THE INVENTION
The cultivar Monroe has not been observed under all possible
environmental conditions. The phenotype may vary somewhat with
variations in environment such as temperature, daylength 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 `Monroe`. These
characteristics in combination distinguish `Monroe` as a new and
distinct cultivar: 1. Numerous multi-petalled white-colored
flowers. 2. Upright, uniform and compact plant habit. 3. Freely
branching growth habit. 4. Dark green glossy leaves. 5. Excellent
postproduction longevity.
Plants of the new Kalanchoe are most similar to plants of the
female parent, the cultivar Leonardo. However, plants of the new
Kalanchoe differ from plants of the cultivar Leonardo primarily in
flower color as plants of the new Kalanchoe have white-colored
flowers whereas plants of the cultivar Leonardo have red
purple-colored flowers. Plants of the new Kalanchoe flower about
two weeks later than plants of the cultivar Leonardo. In addition,
plants of the new Kalanchoe are more compact than plants of the
cultivar Leonardo.
Plants of the new Kalanchoe differ from plants of the male parent,
the cultivar Pablo, in the following characteristics: 1. Plants of
the new Kalanchoe are more compact than plants of the cultivar
Pablo. 2. Plants of the new Kalanchoe have multi-petalled flowers
whereas plants of the cultivar Pablo have about four petals per
flower. 3. Flowers of plants of the new Kalanchoe are white in
color whereas flowers of plants of the cultivar Pablo are pink and
white bi-colored.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates the overall
appearance of the new Kalanchoe, showing the colors as true as it
is reasonably possible to obtain in colored reproductions of this
type. Colors in the photograph may differ slightly from the color
values cited in the detailed botanical description which accurately
describe the colors of the new Kalanchoe. The photograph comprises
a side perspective view of a typical plant of `Monroe` grown in a
container.
DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The
Royal Horticultural Society Colour Chart, 1995 Edition, except
where general terms of ordinary dictionary significance are used.
Plants used for the aforementioned photograph and for the
description were grown during the spring in De Lier, The
Netherlands, in a glass-covered greenhouse. During the production
of the plants, day temperatures ranged from 19 to 26.degree. C.;
night temperatures ranged from 20 to 21.degree. C.; and light
levels ranged from 10,000 to 50,000 lux. Unrooted cuttings were
directly stuck in 10-cm containers and received long day/short
night conditions (more than 14 hours of light) for about three
weeks; plants then received photoinductive short day/long night
conditions (minimum 14 hours darkness) until flowering. Plants were
about 14 weeks old from an unrooted cutting when the photograph and
the description were taken. Botanical classification: Kalanchoe
blossfeldiana cultivar Monroe. Parentage: Female, or seed,
parent.--Kalanchoe blossfeldiana cultivar Leonardo, disclosed in
U.S. Plant Pat. No. 13,365. Male, or pollen, parent.--Kalanchoe
blossfeldiana cultivar Pablo, disclosed in U.S. Plant Pat. No.
11,653. Propagation: Type cutting.--Terminal vegetative cuttings.
Time to initiate roots.--Summer: About 10 days at 21.degree. C.
Winter: About 14 days at 21.degree. C. Time to produce a rooted
cutting.--Summer: About 21 days at 21.degree. C. Winter: About 28
days at 21.degree. C. Root description.--Numerous; fine; fibrous;
greyed white in color. Rooting habit.--Freely branching. Plant
description: Form.--Upright and uniform plant habit. Very freely
flowering with numerous compound cymes. Inverted triangle with
rounded crown. Appropriate for 10 to 15-cm containers. Crop
time.--About 13 to 16 weeks: three to four weeks under long
day/short night conditions followed by ten to twelve weeks of short
day/long night conditions. Moderate growth rate. Plant height at
flowering.--About 15 cm. Plant diameter at flowering.--About 13 cm.
Branching habit.--Freely branching; typically five to seven lateral
branches develop per plant. Pinching (removal of terminal apex) is
not required but will enhance lateral branch development. Lateral
branch description.--Length: About 8 to 10 cm. Diameter: About 2 to
5 cm. Internode length: About 2 to 3 cm. Aspect: Erect. Strength:
Moderately strong. Texture: Smooth, glabrous. Color: 147A. Foliage
description.--Leaves simple, opposite, generally symmetrical.

generative leaves. Length: About 9 cm. Width: About 7 cm. Shape:
Ovate. Apex: Obtuse. Base: Acute. Margin: Slightly crenate.
Texture, upper and lower surfaces: Leathery, glabrous and
succulent. Color: Developing and fully expanded leaves, upper
surface: 147A; glossy. Developing and fully expanded leaves, lower
surface: 147B. Venation, upper surface: 147A to 147B. Venation,
lower surface: 147B. Petiole length: About 1.5 cm. Petiole
diameter: About 4 mm by 8 mm. Petiole color: Upper surface: 147A to
147B. Lower surface: 147B. Flower description: Flower type and

that arise from leaf axils. Freely flowering; more than 25 open
flowers per lateral branch and more than 150 open flowers per
plant. Flowering continuously for at least seven weeks. Flowers
persistent. Flowers not fragrant. Natural flowering season.--Plants
of the new Kalanchoe initiate and develop flowers under short
day/long night conditions or during the late autumn/winter/early
spring. Flower initiation and development can also be induced under
artificial short day/long night conditions (at least 14 hours of
darkness). Time to flower.--Under short day/long night
photoinductive conditions, about ten to twelve weeks are required.
Actual time to flower is primarily dependent upon temperature and
light intensity. Post-production longevity.--Excellent
post-production longevity; plants maintain good foliage and flower
substance for about 45 days under interior environmental
conditions. Individual flowers last about 22 days on the plant.
