Abstract
A new and distinct cultivar of African Violet named ‘EverGrace’ particularly characterized by its multiflorescence trait, single, violet-shaped white flowers with variable amounts of light blue in the center and around the edges, frilled light green edges; strong, upright flower stems that curve slightly toward the center to form a compact flower bouquet above the leaves; medium green, wavy, heart-shaped leaves; vigorous and extra large growth habit; flowering 12-13 weeks after potting, and long-lasting and non-dropping flowers.
Description
Saintpaulia ionantha.
‘EverGrace’.
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 ‘EverGrace’.
The new cultivar was referred to during the breeding and selection process by the designation ‘R 7/1 B’ and is a product of a planned breeding program. The new cultivar is a mutation of Saintpaulia ionantha ‘EverPraise’ (U.S. Plant patent application Ser. No. 10/046,985) discovered by the inventor, Reinhold Holtkamp, Sr., in the controlled breeding program Nashville, Tenn. The female, or seed grandparent was a cultivar designated ‘SB 4-2 Muflo’ (U.S. Plant Patent application Ser. No. 10/046,968). The male, or pollen grandparent was a cultivar designated ‘P 6/6’ (unpatented). ‘SB 4-2 Muflo’ was produced from plants derived from African Violet seeds incubated in a weightless environment in space on the Long Duration Exposure Facility.
In comparison to ‘EverGrace’, ‘SB 4-2 Muflo’ is a multiflorescent cultivar having single, violet-shaped medium blue flowers. The leaves of ‘SB 4-2 Muflo’ are medium green which in contrast to the leaves of ‘EverGrace’ are not wavy, nor crenate. Unlike ‘EverGrace’, the petals of ‘SB 4-2 Muflo’ do not have the light green edge, and the flowers are not bi-colored. In comparison to ‘EverGrace’, ‘P 6/6’ is a cultivar having single, violet-shaped, non-multiflorescent burgundy flowers. Similar to ‘EverGrace’the petals of ‘P 6/6’ have a light green edge.
‘EverGrace’ was discovered and selected by the inventor as a flowering plant within a planting of ‘EverPraise’ in a controlled environment in Nashville, Tenn. Asexual reproduction of the new cultivar by leaf cuttings, as performed by the inventor in Nashville, Tenn., 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. The new cultivar reproduces true-to-type.
‘EverGrace’ 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 without a change in genotype. The following observations, measurements and values describe the new cultivar as grown in Nashville, Tenn. and Haffen, Germany under greenhouse conditions which closely approximate those generally used in commercial practice.
The following characteristics have been repeatedly observed and are determined to be basic characteristics of ‘EverGrace’, which in combination distinguish this African Violet as a new and distinct cultivar:
1) Multiflorescence;
2) A single crown as large as 35-45 cm in diameter;
3) Strong, upright flower stems curving slightly toward the center;
4) Single violet-shaped white flowers with variable amounts of light blue in the center fading towards the edges and around some flower edges; frilled light green edges, especially on the two smaller petals;
5) Each plant carries approximately 12-16, sometimes more, upright flower stems each of which carry 10-14, sometimes more flowers;
6) Long-lasting, non-dropping flowers;
7) Vigorous and compact grower;
8) Plant saleable 12-13 weeks after potting;
9) Seed capsules visible above the petals;
10) Medium-green, wavy, heart-shaped leaves; and
11) After maturity the flowers dry off, and remain on the peduncle without becoming infected by Botrytis.
The new cultivar is most similar to ‘EverPraise’ (U. S. Plant patent application Ser. No. 10/046,985). Both ‘EverGrace’ and ‘EverPraise’ display the multiflorescence trait, have the same extra large growth habit and same type leaves and flower shape with the greenish edge. However, ‘EverPraise’ has medium blue flowers whereas ‘EverGrace’ has bi-colored flowers, white with variable amounts of light blue in the center, fading out to the edges and around some edges. In addition, ‘EverGrace’ has a wider green edge than ‘EverPraise’.
The accompanying color photographic drawing shows a typical plant of the new cultivar ‘EverGrace’. The colors appearing in the photographic drawing are as true as possible with color illustrations of this type. The photographic drawing is a top view of ‘EverGrace’ depicting the leaves and flowers.
In the following description, color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), except where general colors of ordinary significance are referred to. Color values were taken under natural sunlight conditions at approximately 12 p.m. in Nashville, Tenn. Measurements were taken 16-18 weeks from potting, as grown in a 6″ pot.
Parentage: Mutation of Saintpaulia ionatha, Ramat ‘EverPraise’.
Propagation: Leaf cuttings.
Plant: 12 cm to 14 cm tall when grown in pots, and 35-45 cm in diameter when fully grown.

Roots.—Normally developed, white when young, turning slightly brownish when older.
Disease resistance: ‘EverGrace’ has shown very good resistance to all major violet diseases.
General observations: ‘EverGrace’ is a very attractive cultivar due to its abundance of mostly white flowers with variable amounts of light blue in the center, radiating into the petals and around some petal edges and a distinctive light green frilled edge, especially on the two smaller petals. Furthermore, it is an outstanding cultivar due to its multiflorescence trait in which a plant has 2 to 3 flower stems emerging out to each leaf internode, thereby giving the cultivar continuously new buds before the old flowers have wilted.
