African violet plant named Gemini

Abstract

A new and distinct cultivar of African violet named Gemini characterized by its single, bright pink flowers with darker pink center; strong, upright flower stems that curve toward the center to form a compact bouquet above the leaves; medium green, serrated girl-type leaves; profuse flowering, vigorous growth habit, flowering 10-11 weeks after potting, and its long-lasting and non-dropping flowers.

Description

The present invention comprises a new and distinct cultivar of African violet plant, botanically known as Saintpaulia ionantha, and hereinafter referred to by the cultivar name Gemini.

The new cultivar was referred to during the breeding and selection process by the designation G 91/26, and is a product of a planned breeding program. The new cultivar was originated from a cross made by me in the controlled breeding program in Haffen, Federal Republic of Germany. The female, or seed parent was a cultivar designated 40. The male, or pollen parent was a cultivar designated 47.

Gemini was discovered and selected by me as a flowering plant within the progeny of the stated cross in a controlled environment in Haffen, West Germany. Asexual reproduction of the new cultivar by leaf cuttings, as performed by me at Haffen, West Germany, has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction.

Gemini has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length. The following observations, measurements and values describe the new cultivar as grown in Haffen, West Germany and Nashville, Tenn. under greenhouse conditions which closely approximate those generally used in commercial practice.

The following traits have been repeatedly observed and are determined to be basic characteristics of Gemini, which in combination distinguish this African violet as a new and distinct cultivar:

(1) Strong, upright flower stems curving toward the center.

(2) Bright pink single flowers.

(3) Profuse flowering.

(4) Each plant carries 7-8 and more upright flower stems, each of which carries 9-11 flowers.

(5) Long lasting, non-dropping flowers.

(6) Vigorous grower.

(7) Plant saleable 10 to 11 weeks after potting.

(8) Seed capsules push slightly through.

(9) Medium green girl-type leaf, wavy, serrated, with a bright light green center.

(10) After maturity the flowers dry off and remain on the peduncle without becoming infected by botrytis.

The accompanying color photographic drawing shows a typical specimen plant of the new cultivar. The colors appearing in the photograph are as true as possible with color illustrations of this type.

In the following description, color references are made to The Royal Horticultural Society Colour Chart (RHS), except where general colors of ordinary significance are referred to. Color values were taken under natural sunlight conditions at approximately 1 p.m. in Nashville, Tenn.

Botanical Classification: Saintpaulia ionantha, Ramat., c.v. Gemini.

Parentage:

Male parent.--47.

Female parent.--40.

Propagation: The new cultivar holds its distinguishing characteristics through successive propagations by leaf cuttings.

Plant: From 10 cm to 11 cm tall when grown in pots, and approximately 18-20 cm in diameter when fully grown.

Leaves.--General form: Oval, girl-type. Diameter: 60-70 mm. Texture: Velvety. Aspect: Shiny, wavy, serrated, slightly hairy, bright light green center. Veins: Upperside: well visible, light green radiating from the center; underside: very well pronounced, light green, shiny, on young leaves slightly purplish. Color (upperside): Yellow-Green Group 147 between A and B. Color (underside): Greyed-Green Group 193 B. Petiole: Strong upright, light green with purplish touch, hairy.

Flowers.--Buds: Bell-shaped, 7-8 mm just before opening, purplish green. Sepals: Five (5). Color: Green with purplish touch. Calyx: Shape: Funnel-shaped. Aspect: Spear-shaped, hairy. Peduncle: Character: Strong upright, hairy. Color: Purplish red. Individual flowers: Size: 35-40 mm. Shape: Single violet-shaped (3 large and 2 small petals), the size difference becomes very pronounced on older flowers. Color (upperside): Red-Purple Group 74 D, center 74 C. Under cooler temperatures and more intensive lighting, the pink color tends to intensify. Color (underside): Red-Purple Group 74 between C and D. Borne: Each flower stem carries 9-11 flowers on strong, upright peduncles that are free standing above the leaves, thereby forming a compact bouquet. Flowering Habit: Flowers 10-11 weeks after potting.

Reproductive organs.--Stamens: Two (2). Anthers: 2 composed of 4 anther cells, seed capsule pushes slightly through. Filaments: Yellowish green with pink traces, 4 mm long. Pollen Color: Yellow Group 7 A. Styles: 6 mm long, pink, base of ovary light green and hairy.

Roots.--normally developed, white when young, turning slightly brownish when older.

Disease resistance: Good.

General observations: Gemini has a very attractive appearance due to its medium green, serrated leaves with a light green center. A tight bouquet of flowers free standing above the leaves develops after approximately 10-11 weeks. Each of the 7-8 and more flower stems carries 9-11 bright pink single violet-shaped flowers. The pink color in the center of the flower is darker, especially on the two small petals. Occasionally, 1-2 additional small petals may develop. The flowers are long-lasting and non-dropping.
