| Abstract: |
A Kalanchoe plant named Small Wonder particularly characterized by its orange-red flower color with red highlights; flower diameter of 14 to 16 mm at maturity; flowering response of from 10 weeks in summer to 12 weeks in winter after start of short days; very floriferous habit with excellent display of many flowers; excellent keeping quality of flowers and foliage; foilage always small, medium green, nicely serrated and lobed; free branching with or without pinching; compact plant habit with intermediate vigor; responsive to B-9 applications to reduce internode length and peduncle elongation; and adaptable to pot sizes from 10 to 15 cm. |
| Claim: |
I claim:
1. A new and distinct plant of Kalanchoe named Small Wonder, as described and illustrated. |
| Description: |
The present invention relates to anew and distinctive cultivar of Kalanchoe plant, botanically known as Kalanchoe blossfeldiana Poelln., and referred to by the cultivar name Small Wonder.
Small Wonder, identified as 409-021, is a product of a planned breeding program which had the objective of creating new Kalanchoe cultivars for year-round commercial production, with earlier flowering response, good branching yet compactflowering plants, suitable for flowering in pots ranging from 10 to 15 cm, and with good flower and foliage keeping quality.
Small Wonder was originated from a cross by the inventor Margaret M. Fleming in a controlled breeding program in Half Moon Bay, Calif., in 1983.
The female parent of Small Wonder was the cultivar Eternity, disclosed in U.S. Plant Pat. No. 5,253. The male parent was the cultivar Regulus, disclosed in U.S. Plant Pat. No. 4,817.
Small Wonder was discovered and selected by the inventor as one flowering plant within the progeny of the stated cross in September, 1984 in a controlled environment in Half Moon Bay, Calif.
The first act of asexual reproduction of Small Wonder was accompilshed when vegetative cuttings were taken by the inventor from the initial selection in January, 1985 in a controlled environment in Half Moon Bay, Calif.
Horticultural examination of controlled flowerings of successive plantings has shown that the unique combination of characteristics as herein disclosed for Small Wonder are firmly fixed and are retained through successive generations of asexualreproduction. Small Wonder has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and daylength.
The following observations, measurements and comparisons described plants grown in Soquel, Calif., under greenhouse conditions which approximate those generally used in commercial greenhouse practice.
The following traits have been repeatedly observed and are determined to be basic characteristics of Small Wonder, which, in combination, distinguish this Kalanchoe as a new and distinct cultivar:
1. Orange-red flower color with red highlights.
2. Flower diameter of 14 to 16 mm at maturity.
3. Flowering response of from 10 weeks in summer to 12 weeks in winter after start of short days.
4. Very floriferous, with excellent display of many flowers.
5. Excellent keeping quality of flowers and foliage.
6. Foliage always small, medium green, nicely serrated and lobed.
7. Branches freely with or without pinching.
8. Compact plant habit with intermediate vigor.
9. Responds well to B-9 applications to reduce internode length and peduncle elongation.
10. Proper scheduling makes this new cultivar suitable for production in 10 cm to 15 cm pots.
The accompanying photographic drawings show typical inflorescence and leaf characteristics of Small Wonder, with colors being as nearly true aspossible with illustrations of this type. Sheet 1 is a color photograph of Small Wonder grown as a non-pinched flowering Kalanchoe in a 10 cm pot. Although the leaf edges appear to have a dark or reddish tone, this is a photographic imperfection andnot a characteristic of Small Wonder. Sheet 2 is a black and white photograph showing the leaves of Small Wonder at three stages of development (mature, intermediate and immature).
Of the commercial cultivars known to the inventor, none aresuitable for comparison with Small Wonder. The orange-red flower color with red highlights is unique. The foliage is different from any known variety: medium green, nicely serrated and lobed, with excellent keeping quality. However, floweringresponse, productivity, plant habit, responsiveness to B-9 applications, and adaptability to various pot sizes of Small Wonder compares with the cultivar Fascination, disclosed in U.S. Plant Pat. No. 5,889.
When compared to the female parent Eternity, Small Wonder is more vigorous, and its foliage is much smaller, less fleshy and a lighter green in color. The leaf lobes of Small Wonder are unique. Small Wonder blooms 1-3 weeks earlier thanEternity, branches much more freely than Eternity (or any other cultivar known to the inventor), and has as good or better keeping quality than Eternity, which has been the industry standard for keeping qualities ever since its introduction. A furtherdistinction is in the substantially different shades of orange of the respective flowers.
Comparing Small Wonder to its male parent Regulus, Small Wonder is more vigorous and its foliage is lobed in a distinctive way, is less fleshy, and is a lighter green color and much more durable. Regulus, which has a beautiful orange flowercolor when grown well, tends toward foliage degradation and an oversensitivity to salt buildup and overwatering which makes the root system susceptible to damage. Small Wonder did not inherit these weaknesses from Regulus.
In the following description color references are made to The Royal Horticultural Society Colour Chart. The color values were determined on plant material grown as a non-pinched pot plant in a 10 cm pot in Soquel, Calif., on Oct. 23, 1988.
Classification:
Botanical.--Kalanchoe blossfeldiana Poelln. cv. Small Wonder.
Commercial.--Flowering pot Kalanchoe.
Parentage:
Female parent.--Eternity (U.S. Plant Pat. No. 5,253).

Flowering description:
(A) Flowering habit.--Inflorescence of each shoot is formed by dichotomous branching, starting with opening of terminal flower of main axis, followed by terminal flowers of the side branches, continuing with subsequent development of branches inthe inflorescence.
