| Abstract: |
A new and distinct cultivar of Impatiens plant named Lanai, characterized by its large, bright red flowers, compact growth habit with excellent selfbranching without pinching, medium green foliage, very early and uniform flowering, floriferous habit, and by its suitability to pot or hanging basket culture. |
| Claim: |
I claim:
1. A new and distinct cultivar of Impatiens plant named Lanai, as illustrated and described. |
| Description: |
The present invention relates toa new and distinct cultivar of plant known as Impatiens and commercially known as New Guinea Impatiens. The new cultivar is known by the cultivar name Lanai, and was developed by the inventor Ludwig Kientzler in Gensingen, Federal Republic of Germany bycrossing the cultivar designated D-456 (seed parent) with the cultivar Selenia (pollen parent). Selenia is disclosed in U.S. Plant Pat. No. 6,731.
Asexual reproduction by terminal (stem tip) cuttings taken by me or under my supervision at Gensingen, Federal Republic of Germany, has shown that the unique features of this new Impatiens are stabilized and are reproduced true to type insuccessive propagations.
The following characteristics distinguish the new Impatiens from both its parent varieties and other cultivars of this general type known and used in the floriculture industry:
1. Compact growth habit with excellent branching characteristics. Plants in 16.5 cm pots were 16.5 cm tall and 25 cm wide, eight weeks after planting.
2. Large, bright red flowers. Open flowers measure up to 6 cm in diameter.
3. Early flowering and very floriferous. Plants in 16.5 cm pots were in flower 7 weeks after planting.
4. Medium green foliage.
5. Well suited both to 4" pot and 8" hanging basket culture.
Lanai is similar in many respects to the parent cultivar Selenia and the cultivar Anaea, disclosed in a pending application of applicant. However, the flower color of Lanai is a unique bright red. The color is not as dark red as Anaea and notas orange as Selenia. The leaf color and growth habit of Lanai are similar to both Anaea and Selenia.
The accompanying colored photograph is a top perspective view of the new cultivar, showing color as true as it is reasonably possible to obtainin a colored reproduction of this type.
The following is a detailed description of my new Impatiens cultivar based on plants grown under commercial practice in Encinitas, Calif. Plants were started as rooted cuttings and were transplanted inmid-December into 16.5 cm (6.5 inch) pots, one pot per plant. By med-February, plants were growing vigorously and were in flower. The values, measurements and observations noted below were taken from plants in full bloom in mid-February.
Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), except where general terms of ordinary dictionary significance are used.
Parentage: Cross between D-456 (seed) and Selenia (pollen).
Asexual reproduction:
A. Cutting type.--Tip, with stems 2-3 cm long developing to 4-5 cm after 21 days in propagation.
B. Time to initiate roots.--8-10 days at 23.degree. C.; nicely developed root mass in 18-21 days.
C. Rooting habit.--Numerous, fibrous, adventitious roots from the stem.
Plant description:
A. Form.--Symmetrical, bush shaped, flowering herb, with self-branching characteristics giving the plant a full appearance. Pinching is not recommended since it does not enhance branching and only delays flowering by removing flower buds.
B. Habit of growth.--Vigorous, self-branching habit, producing whorls of leaves and flowers. Growth is indeterminate and flowering is continuous.
C. Foliage description.--Leaves are simple. Lower leaves on stems are opposite. Higher leaves in whorls of 3-5, but predominately 5. 1. Leaf shape: ovate. Leaf blade tips are acuminate; bases are acute. 2. Leaf blade size: Mature leaves11-12 cm long and 4.5 to 5 cm wide. 3. Petiole length: Approximately 2 cm. 4. Leaf margin: Ciliated and finely serrated. 5. Leaf texture: Slightly rugose. a. Upper surface: Vestiges of setae distributed evenly across leaf surface. b. Undersurface: Glabrous. 6. Leaf color: Medium green with a reddish petiole. a. Upper surface: Near, but darker than 147A. b. Under surface: Greyed green, near 191A to 191B. Leaf veins are reddish. 7. Venation: Pinnate.
Flowering description:
A. Flowering habits.--Very floriferous. Flowering is continuous. Flowers develop progressively around the whorl of leaves, taking 5-7 days from buds which show color, to bloom. Flowers are single and large, lasting for 2-3 weeks.
B. Natural flowering season.--Flowering is indeterminate and occurs throughout the year. Quantity of flowers increases with increasing light intensity and duration. However, floriferousness may wane during hot summer days in temperate climates.
C. Flower buds.--Ellipsoidal and covered with 3 sepals plus 2 rudimentary sepals fused into the under surface of the superior petal. A spur originates from the base of the inferior sepal. Spur is reddish and approximately 5 cm long.
D. Flowers borne.--Singly, on reddish pedicels about 5 cm long.
E. Quantity of flowers.--Usually two flowers per leaf. Flowers occur progressively around the whorl of leaves so that tight buds to mature flowers are visible at the same time.
F. Petals.--Petals open nearly perpendicular to the pedicel so the plane of the flower surface is nearly flat. 1. Number of petals: Five (5) petals, all overlapping. 2. Shape: All petals are heart-shaped. Superior petal has a broad base. Other petals have a pointed base. 3. Color: Petals open nearly perpendicular to the pedicel so the plane of the flower surface is nearly flat. a. Upper surface: Near 44A. b. Under surface: Between 44B and 44C. 4. Flower size: Up to 6 cm indiameter.
G. Reproductive organs.--FLowers are monoecious. 1. Stamens: Five (5), broad and fused to form a tube around the ovary; red in color. 2. Anther: Hooded and cream colored. 3. Pollen: Cream colored. 4. Stigma: Five pointed star, colorless. 5. Styles: Very short. 6. Ovary: 5-celled, 4-5 mm long until fertilized. Grows to 1 cm or longer after fertilization; green.
Resistance to disease: Good resistance to common stem and root disease, Rizoctonia and Pythium. Botrysis may be a problem in humid or mist propagation environments, but no greater than with other New Guinea Impatiens cultivars.
