Floribunda rose plant named ‘Meipojona’

Abstract

A new and distinct Floribunda rose plant is provided that originated as a branch sport of the ‘Meipomolo’ variety (U.S. Plant Pat. No. 16,342). Unlike the ‘Meipomolo’ variety, the new variety forms golden-yellow blossoms instead of yellow-orange blossoms. The attractive blossoms are formed on a nearly continuous basis. The growth habit is vigorous and bushy. The semi-glossy foliage is dense dark green and of good substance and contrasts nicely with the golden-yellow blossom coloration. Very good tolerance to Black Spot and Oidium is displayed under normal growing conditions. The plant is well suited for growing as attractive ornamentation in parks and gardens.

Description

Botanical/commercial classification: Rosa hybrida/Floribunda Rose Plant.

Varietal denomination: cv. ‘Meipojona’.

SUMMARY OF THE INVENTION

A single plant of the new variety was discovered as a branch sport at Le Cannet - Des - Maures, Le Luc, France, while growing in rose fields among plants of the ‘Meipomolo’ variety (U.S. Plant Pat. No. 16,342). The mutation was of unknown causation. I was attracted to the plant primarily because of its distinctive flower coloration. Subsequently the plant has undergone detailed observation and study. Had I not discovered and preserved the new plant it would have been lost to mankind.

It was found that the new variety of Floribunda rose plant of the present invention possesses the following combination of characteristics:

• • (a) forms on a nearly continuous basis attractive bright golden-yellow blossoms,
  • (b) exhibits a vigorous and bushy growth habit,
  • (c) forms decorative dense dark green semi-glossy foliage of good substance,
  • (d) displays good tolerance to Oidium and Black Spot, and
  • (e) is well suited for growing as attractive ornamentation in parks and gardens.

The golden-yellow blossom coloration is luminous in character and contrasts nicely with the dark green foliage. The plant is well suited for growing in U.S.D.A. Hardiness Zone No. 6.

The new variety of the present invention can be readily distinguished from its ‘Meipomolo’ ancestor. More specifically, the blossoms of the ‘Meipomolo’ variety are yellow-orange unlike the golden-yellow coloration of the new variety.

The new variety of the present invention also can be readily distinguished from other similar Floribunda rose varieties, such as the ‘Meibeausai’ (U.S. Plant Pat. No. 7,667) and ‘Meimonblan’ (U.S. Plant Pat. No. 12,579) varieties. Each forms blossoms having a different coloration. The ‘Meibeausai’ variety forms white blossoms and the ‘Meimonblan’ variety forms darker tangerine orange blossoms.

The new variety well meets the needs of the horticultural industry and is particularly well suited for enhancing the appearance of the landscape. It can be grown in a hedge or mass planting.

The new variety has been found to undergo asexual propagation in the South of France and at Wasco, Calif., U.S.A., by a number of routes, including budding, grafting, and cuttage. Asexual propagation by the above-mentioned techniques at these locations has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another.

The new variety has been named the ‘Meipojona’, and will be marketed under the TEQUILA GOLD trademark.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show as nearly true as it is reasonably possible to make the same, in a color illustrations of this character, typical specimens of the new variety. The rose plants of the new variety were two years of age and were observed during June while budded on Rosa froebelli understock and growing outdoors near West Grove, Pa., U.S.A.

FIG. 2—illustrates a typical flowering plant of the new variety. The vigorous bushy growth habit is shown.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The description is based on the observation of two year-old plants during June while budded on Rosa froebelli understock and growing outdoors near West Grove, Pa., U.S.A. Reference to color in common terms is to be accorded its ordinary dictionary significance.
