Title: Kalanchoe plant named ‘Forever Midi Orange Ember’

Description:
The present invention relates to a new and distinct cultivar of Kalanchoe plant, botanically known as  Kalanchoe blossfeldiana,  and known by the cultivar name ‘Forever Midi Orange Ember’. ‘Forever Midi Orange Ember’ was developed in a controlled breeding program in Ashtabula, Ohio by crossing Mikkelsen Seedling No. 91-180-1 (seed parent) (unpatented) with Mikkelsen Seedling No. 90-170-1 (pollen parent) (unpatented). The seed and pollen parents are proprietary breeding lines which have not been sold or made publicly available in this country. The plant is perennial but typically used as an annual in the floriculture industry. 
     Asexual reproduction by stem cuttings taken by the inventor in Lompoc, Calif. has shown that the unique features of this new Kalanchoe are stabilized and are reproduced true to type in successive propagations. 
     The following characteristics distinguish the new Kalanchoe from other cultivated Kalanchoes of this type known to the inventor. The characteristics are described with comparative reference to the cultivars Merit (U.S. Plant Pat. No. 9,675) and Tico Dark Orange (U.S. Plant Pat. No. 8,998). 
     1. ‘Forever Midi Orange Ember’ has deep orange colored flowers of Orange-Red Group 34A with the flowers of ‘Merit’ being lighter at Orange-Red Group 30A and ‘Tico Dark Orange’ having flowers colored Orange-Red Group 33A. 
     2. ‘Forever Midi Orange Ember’ has shorter leaves (7 to 8 cm) than ‘Merit’ (8 to 9 cm) and similar to ‘Tico Dark Orange’ but ‘Tico Dark Orange’ has narrower leaves at 4.0 to 4.5 cm than ‘Forever Midi Orange Ember’ which are 4.5 to 5.0 cm wide. 
     3. ‘Forever Midi Orange Ember’ is intermediate in height at 15 cm between ‘Merit’ at 13 cm and ‘Tico Dark Orange’ at 17 cm. 
     4. ‘Forever Midi Orange Ember’ is intermediate in growth habit with ‘Merit’ being more mounded and ‘Tico Dark Orange’ being more upright. 
     5. ‘Forever Midi Orange Ember’ has a denser fuller flower display due to its highly branched nature with ‘Merit’ and ‘Tico Dark Orange’ being more open in the floral display. 
     6. ‘Forever Midi Orange Ember’ has a deeper red-purple cast to the stigma than ‘Tico Dark Orange’ and ‘Merit’ having white colored stigma when mature. 
     7. ‘Forever Midi Orange Ember’ has superior keeping quality of 5 to 7 days longer than ‘Merit’ and ‘Tico Dark Orange’. 
     8. ‘Forever Midi Orange Ember’ has completely green leaves while ‘Tico Dark Orange’ has anthocyanin pigmentation at leaf margin of top part of older leaves. 
    
    
     The accompanying colored photograph illustrates the overall appearance of this cultivar, as described in detail below, taken as a face view of the plant and showing the colors as true as it is reasonably possible to obtain in a colored reproduction of this type. 
    
    
     The following is a detailed description of the new cultivar, based on plants produced in greenhouses in Lompoc, Calif. during the Winter season of the year. Plants were grown in 10 cm pots and measurements were taken 13 weeks after rooted cuttings were planted. Height measurements were taken from the soil line of the container. The plants were grown at 16° C. night temperatures, 3000-4000 foot candles of light, and 200 ppm nitrogen, 75 ppm potassium, and 200 ppm phosphorous nutritional levels, with trace elements added. Habit of growth, foliage coloration, size of leaves, and peduncle length will be greatly influenced by nutritional and environmental conditions. 
     Color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. 
     Parentage: A controlled cross between female parent Mikkelsen Seedling No. 91-180-1 and male parent Mikkelsen Seedling No. 90-170-1. 
     Propagation: 
     ( A )  Type cutting.— Stem tip cuttings up to 3 cm long. 
     ( B )  Time to root.— 10 days at 21° C. summer; 12 days at 21° C. winter. 
     ( C )  Rooting habit.— Fine, fibrous, abundant. 
     Plant description: 
       Habit and form of growth.— Compact, semi-mounded, excellent basal branching; flower clusters bloom above foliage. Environment and use of growth regulators will play a role in final height. Average height is 20 cm and average width is 20 cm. Internode length is typically 12 mm. Main stem diameter is 10 mm, stem texture is smooth, glabrous and stem color is Yellow-Green Group 147A. 
       Foliage description.— Leaves simple and opposite. Leaves are petiolate and petioles are Yellow-Green Group 147A having a length of 14 mm and width of 5 mm. Size: Average, full grown leaves on a plant when grown in a 10 cm pot are 7 to 8 cm long and 4.5 to 5 cm wide. Shape: Ovate with obtuse apex and acute base. Texture: Glabrous; coriaceous and succulent. Margin: Crennate; shallow lobed. Color: Young foliage top side is Yellow-Green Group 147A, underside is Yellow-Green Group 146A; mature foliage top side is Yellow-Green Group 147A, underside is between Yellow-Green Groups 147A and 147B. 
       Branching.— Average number of lateral branches is 8. The average lateral branch length is 15 cm and average lateral branch diameter is 5 mm. The branch texture is smooth, glabrous and color is Yellow-Green Group 147A. 
     Flowering description: 
       Flowering habits.— Inflorescence is a compound dichasial cyme. Terminal flower on main axis opens first followed by the terminal flowers of the side branches, continuing with the subsequent development of branches in the inflorescence. Inflorescence is made up of the main stem and up to 8 or more lateral branches depending on growing schedule followed. 
       Natural flowering season.— Early January. Flowering time under controlled daylength (10 hours daylight, 14 hours darkness) at 20° C. in summer is 8.5 to 9 weeks; in winter is 10 to 10.5 weeks. Flowering time depends on temperature, light intensity and other growing conditions. 
       Flower buds.— Oblong, up to 10 mm long before showing color, developing to tubular as flower petals mature; sheated in four (4) sepals colored Yellow-Green Group 146C. Sepals are individual with a lanceolate shape. Sepals are 8 mm long and 2 mm wide. 
       Flowers borne.— Compound dichasial cyme with primary peduncle being 4 mm in diameter just below the first branch of the inflorescence; length of peduncle will vary depending on growing conditions. The average number of peduncles is 10 with an average length of 10 cm, average diameter of 4 mm, smooth, glabrous texture and Yellow-Green Group 147A color. The average number of pedicels is 250 with an average length of 3 mm, average diameter of 1 mm, smooth, glabrous texture, and Yellow-Green Group 147A color. Pedicels vary in length depending on where they are in the inflorescence. 
       Quantity of flowers.— Numerous flowers on the main stem plus the 8 or more lateral branches will have 25 or more flowers each. Approxiamte time period for bloom lastingness is 4 to 6 weeks. The florets are flat in shape. 
       Petals.— Shape: Almost rounded, top cuspidate. Color: Top side when opening is Orange-Red Group 34A with no fading apparent. Underside is Orange-Red Group 29C. Number of petals: 4. 
       Reproductive organs.— Stamens: 8 in number, with an average size of 3 mm not fused to the petal. Anthers: Flat, elliptical in shape, yellow-green in color. Filament color: Yellow-green. Pollen: Abundant, yellow. Pistils: Average of 4 per flower with an average size of 12 mm. Stigma: Flat in shape, mature color is white with red-purple cast. Style color: Light green. Ovaries: 4 in number, size 10 mm when immature, color Yellow-Green Group 146C. 
       Feertility.— The plants are fertile, but do not normally set seed under greenhouse or garden conditions, unless in a controlled crossing program. 
     Disease resistance: ‘Forever Midi Orange Ember’ has shown resistance to powdery mildew. No disease problems have been observed to date. 
     OTHER IMPORTANT CHARACTERISTICS 
     1. Due to highly branched compact growth habit, the plant can be finished in a 10 cm pot without use of growth regulators. 
     2. Excellent basal branching produces a plant with excellent flower coverage over top and sides of plant. 
     3. Pinching is not required or recommended.
