Fragaria plant named ‘Franor’

Abstract

A new and distinct cultivar of strawberry plant named ‘Franor’ characterized by the large single bright red-purple flowers which bloom starting from mid-May and continuing through to early November or until the first frost, bushy clumps which spread out by runners to form a carpet of foliage, its 5 or 6 flower petals which are separately formed and normally spaced, and its versatility of use for border, ground covers, in tubs, or in hanging baskets.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of strawberry plant named ‘Franor’. Strawberry plants are hardy perennial herbaceous plants of the genus Fragaria, a member of the Rosaceae family.

The new cultivar is the result of a spontaneous mutation occurring on a plant of the parent cultivar ‘Frel’, disclosed in U.S. Plant Pat. No. 7,598. The new cultivar is a naturally occurring sport from Fragaria ‘Frel’. The Genus is Fragaria, which is a member of the Rosaceae family. Fragaria ‘Frel’, from which the instant plant originated, is a cross between Potentilla palustris and Fragaria grandiflora. The mutation was discovered by the inventor Walter Bittner in Hamm, Federal Republic of Germany, with the mutative portion of the parent plant being removed from the parent plant, grown and observed. The much brighter red-purple flower color of the mutative portion of the plant was readily observable and led to the discovery.

The instant plant was first asexually reproduced by the inventor in Hamm, Federal Republic of Germany, by taking runners from the initially discovered mutation. This, along with subsequent generations of asexual reproduction, have clearly established that the new cultivar propagates true from generation to generation. The instant cultivar reproduces true to type, generation to generation.

The new cultivar is similar in many respects to the parent cultivar ‘Frel’. The flower shape, foliage shape and color, and relatively minor production of fruit are similar for both cultivars. The primary difference between ‘Franor’ and ‘Frel’ is in flower color, with the flower petals of ‘Franor’ being a very bright red-purple (RHS 57A), compared to the much lighter, pinkish red-purple flower color of ‘Frel’. In addition, there are 5 or 6 petals in ‘Franor’ which, when mature, tend to be spaced one from the other. By contract,‘Frel’ has 6 or 7 petals which often overlap. Also, ‘Franor’ has 2 to 5 fewer stamens and the stamens also tend to be spaced further apart than the stamens of ‘Frel’.

BRIEF DESCRIPTION OF THE INVENTION

The following characteristics in combination distinguish ‘Franor’ from the parent and other known cultivars of this type known to the inventor:

1. ‘Franor’ has achieved the aim of being a quality flowering perennial displaying quality foliage and flowers. The many large single bright red-purple flowers make an excellent display from mid-May to early November, or indeed till the first frost.

2. The new cultivar forms bushy clumps which will flower for many weeks starting mid-May through to early November under normal growing techniques in the United Kingdom. These clumps will spread out by runners, joining together to form a carpet of foliage. The obovate glossy semi-evergreen leaves make a green backdrop to the many large single bright red-purple flowers.

3. The plant thrives best in full sun and well-drained soil, although the plant will also tolerate partial shade.

4. The flowers are of a classic Fragaria flower shape, but 5-6 petals are formed which are clearly separate and spaced apart on mature flowers. The obovate glossy semi-evergreen leaves resemble those of ‘Frel’.

5. As with ‘Frel’, ‘Franor’ produces only a small amount of edible strawberries, being grown primarily for its flowering properties. Only about 30% of the flowers of ‘Franor’ will produce fruit, similar to ‘Frel’.

6. The new cultivar is very versatile, being used for borders, ground covers, in tubs, and in hanging baskets.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of the new cultivar, based on plants grown in Germany and England. Plants described were about one year old. All color determinations and comparisons are based on The Royal Horticultural Society (R.H.S.) Colour Chart. The plants were observed in Bressingham, England, under UK conditions. The plants were grown in 5 liter containers. The instant plant requires a pollinator and will not reproduce from seed.

Origin: A spontaneous mutation from Fragaria ‘Frel’.

Habit: Low bushy clumps.

Size: Mature plants are 20 cm in height with a spread of 60 cm, spreading by runners.

Root system: Fibrous.

Plant vigor: A herbaceous perennial that shows vigorous and healthy growth throughout Great Britain. Plants raised from runners taken in July, fill 5 liter containers in 12 months. Propagation of plugs to 1 liter takes approximately 10 weeks. Normally, cuttings are taken in July, then over the winter, and potted to 1 liter in February, ready for sale in April.

Blooming habit: Abundant showy single red-purple flowers with yellow centers. The flowers are borne on cymes and are positioned well above the foliage. The flowers display clearly separate petals.

Blooming period: From mid-May continuing into early November or until the first frost.

Hardiness: Winter hardy throughout the British Isles and on Mainland Europe. Although the plant has not been fully tested for maximum summer tolerance, it has been grown above 32° C. (90° F.).

Pest and disease resistance: Fragaria ‘Franor’ shows no more suscepibility to pest and disease resistance than Fragaria ‘Frel’; it has been grown over successive generations and has been found to be vigorous and healthy.
