Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

(1) The accompanying colored photographs illustrate the overall appearance of the new Kalanchoe plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Kalanchoe plant.

(2) The photograph on the first sheet is a side perspective view of a typical flowering plant of Dokalnol grown in a container.

(3) The photograph on the second sheet is a close-up view of a typical open flower and flower buds of Dokalnol.

DETAILED BOTANICAL DESCRIPTION

(4) The aforementioned photographs and following observations, measurements and values describe plants grown during the autumn in 10-cm containers in a glass-covered greenhouse in De Lier, The Netherlands and under cultural practices typical of commercial Kalanchoe production. During the production of the plants, day temperatures ranged from 20 C. to 22 C., night temperatures ranged from 19 C. to 21 C. and light levels ranged from 10,000 lux to 55,000 lux. Plants received long day/short night conditions (more than 14 hours of light) for three weeks then plants received photoinductive short day/long night conditions (minimum 14 hours darkness) until flowering. Plants were 16 weeks old when the photographs were taken and 17 weeks old when the description was taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.

Time to produce a rooted young plant, summer.About three weeks at temperatures about 21 C. Time to produce a rooted young plant, winter.About four weeks at temperatures about 21 C. Root description.Fine, fibrous; typically greyish white in color, actual color of the roots is dependent on substrate composition, water quality, fertilizer type and formulation, substrate temperature and physiological age of roots.

Plant height at flowering.About 16 cm. Plant diameter at flowering.About 17 cm. Branching habit.Freely branching habit with about five to eight lateral branches developing per plant; pinching (removal of the terminal apex) is not required but will enhance lateral branch development. Lateral branch description: Length.About 10 cm to 14 cm. Diameter.About 2 mm to 4 mm. Internode length.About 2 cm to 4 cm. Aspect.Mostly upright. Strength.Moderately strong. Texture.Smooth, glabrous. Color.Close to 138A. Leaf description: Arrangement.Opposite, simple; generally symmetrical. Quantity per plant.Typically about six to ten mature leaves and about six to nine generative (developing) leaves. Length.About 9.5 cm. Width.About 6.5 cm. Shape.Ovate. Apex.Obtuse. Base.Obtuse. Margin.Lobed, lobes vault-shaped. Texture and luster, upper and lower surfaces.Smooth, glabrous; coriaceous; succulent; glossy. Venation pattern.Pinnate.

Fragrance.None detected. Natural flowering season.Plants of the new Kalanchoe initiate and develop flowers under short day/long night conditions or during November and December in the Northern Hemisphere; flower initiation and development can also be induced under artificial short day/long conditions (at least 14 hours of darkness). Time to flower.Early flowering habit, under short day/long night photoinductive conditions, plants begin flowering about nine to eleven weeks; actual time to flower is primarily dependent upon temperature and light intensity.
