| Abstract: |
An impatiens plant named Aurore having bright orange-red flowers which provide an attractive contrast with the dark red-green foliage. The growth habit is upright and vigorous, with very good branching. The plant flowers early and profusely. |
| Claim: |
I claim:
1. A new and distinct cultivar of impatiens plant named Aurore, as illustrated and described, and parts thereof. |
| Description: |
The presentinvention relates to a new and distinct cultivar of impatiens plant known by the cultivar name Aurore, and botanically known as impatiens.
Aurore was developed by applicant through a controlled breeding program in Bad Kreuznach, Federal Republic of Germany. Both the male and female parents are unknown at this time. Aurore was discovered and selected as one flowering plant withinthe progeny of the cross by applicant in a controlled environment in Bad Kreuznach, Federal Republic of Germany.
The first act of asexual reproduction of Aurore was accomplished when terminal or stem cuttings were taken from the initial selection by applicant in a controlled environment in Bad Kreuznach, Federal Republic of Germany. Horticulturalexamination of selected plants of Aurore has demonstrated that the combination of characteristics as herein disclosed for Aurore are firmly fixed and are retained through successive generations of asexual reproduction.
Aurore has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity, soil conditions, nutrient feeding, and day length.
The following characteristics distinguish the new impatiens from both its parent varieties and other cultivated impatiens of this type known and used in the floriculture industry within the knowledge of applicant:
1. Dark orange-red flowers.
2. Dark red-green leaves which contrast well with flower color.
3. The plant flowers early and is very floriferous.
4. The growth habit is upright and vigorous with very good branching.
The accompanying colored photograph illustrates in perspective view the overall appearance of this cultivar, with colors being as true as it is reasonably possible toobtain in a colored reproduction of this type.
The following is a detailed description of Aurore based on plants produced under commercial practice in Encinitas, Calif. Unrooted cuttings were rooted in March under intermittent mist, and theplants subsequently transplanted to 6" pots. Flowering commenced in July, and a plant nicely proportioned for a 6" pot was ready five or six weeks later. Most of the data which follows was collected between September 1-5 in Encinitas, Calif. Themeasurements and description of foliage were taken from fully expanded leaves.
Color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. Color chart correlations were made indoors but under natural light conditions, with the leaves andflowers being compared to The R.H.S. Colour Chart near a west-facing window.
Parentage: Seedling from cross pollination, with both the male and female parents being unknown at this time.
Propagation:
Type cutting.--Tip cutting. Stems 2-3 cm long will develop to 4-5 cm after 21 days in propagation.
Time to initiate roots.--8-10 days at 73.degree. C. Nicely developed root mass in 18-21 days.
Rooting habit.--Numerous, fibrous adventitious roots from the stem.
Plant description:
Form.--Symmetrical, bush shaped, flowering herb, with self-branching characteristics giving the plant a full appearance.
Habit of growth.--Vigorous, self-branching, upright habit, producing whorls of leaves and flowers on branched stems. Growth is indeterminate and flowering is continuous.
Foliage description.--Leaves are simple. Lower leaves on stem are opposite. Higher leaves in whorls of 5. Leaf shape: Ovate with acuminate tip and acute base. Leaf blade size: 7-8 cm.times.3.5-4 cm. Leaf margin: Ciliate, finely serrated. Leaf texture: Upper surface: glabrous. Under surface: glabrous. Leaf color: Dark green, older leaves have yellow variegation on either side of mid vein at the base (near 14C). Upper surface: Darker than 139A. Under surface: Between 187A and 187B. Venation: Pinnate, red mid vein.
Flowering description:
Flowering habits.--Very floriferous, flowering continuously. 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.
Natural flowering season.--Flowering is indeterminate and occurs throughout the year. Quantity of flowers increases with increasing light intensity and duration.
Flower buds.--Ellipsoidal and covered with 3 sepals. A reddish approximately 4 cm long spur originates from the base of the major sepal. Two additional, rudimentary sepals are fused to back of the top petal.
Flowers borne.--Singly, on pedicels 3.5 cm long, pedicels reddish in color.
Quantity of flowers.--Floriferous. Two flowers per leaf occurring progressively around the whorl of leaves so that tight buds to mature blooms are visible at the same time in large numbers.
Petals.--Number of petals: Five (5). Shape: Top petal heart shaped with wide base, all other petals heart shaped with pointed base. All petals overlap. Color: Orange-red. Upper surface: Darker and brighter than 33A. Under surface: 40B. Sizeof flowers: 4.5-5 cm.
Reproductive organs.--Stamens: Five (5) with the lower stamen being shorter than the other stamens. Stamens united in an asymmetrical tube surrounding the ovary. Anthers: Hooded, cream fused with red. Pollen: Cream color. Stigma: Five pointedstar, colorless. Styles: Very short, reddish in color. Ovary: 5 celled, 4-5 mm long until fertilized, green in color.
