Description

Botanical/commercial classification: Gazania linearis/Treasure Flower.

Varietal denomination: cv. Tangerine Frost.

SUMMARY OF THE INVENTION

The present invention comprises a new and distinct cultivar of Gazania plant and hereinafter is referred to by the cultivar name ‘Tangerine Frost’. Gazania plants are members of the Asteraceae Family, and are commonly grown as an ornamental perennial which forms daisy-like blossoms.

The new cultivar of the present invention was discovered during June, 2003, in a nursery setting at Bridgeton, N.J., U.S.A. Such new cultivar was discovered as a partial plant mutation of unknown causation on a small portion of a single plant of the ‘Colorado Gold’ cultivar (non-patented in the United States). The parent plant at the time of the discovery was approximately 12 to 15 months of age. Such parent plant had been started from a plug and once had been transplanted.

The discoverer was attracted to the new cultivar primarily in view of its distinctive blossom coloration which differed from that of the parent ‘Colorado Gold’ cultivar and all other Gazania cultivars of which the discoverer was aware. The new plant of the present invention following its discovery has been carefully maintained and evaluated.

It was found that the new Gazania plant possesses the following combination of characteristics:

• • (a) forms attractive rich orange daisy-like blossoms of good substance bearing petals which on the upper surface are rich orange with yellow tips,
  • (b) displays a long blooming season with repeat blooming which commonly begins during May and ends during mid-September in U.S.D.A. Hardiness Zone No. 6,
  • (c) displays attractive dark green semi-evergreen foliage having pubescence on the under surface,
  • (d) exhibits a propensity to readuly produce new crown tissue, and
  • (e) displays good winter hardiness.

The new cultivar resembles the blooming habit of its ‘Colorado Gold’ parent in the sense that it commonly possesses an unusually long and substantially continuous blooming season of up to approximately 120 days in U.S.D.A. Hardiness Zone No. 6. The new cultivar has been found to be hardy to at least −20° F. unlike most other species of Gazania which commonly are hardy to only approximately 32° F.

The new cultivar is well suited for forming attractive ornamentation when grown in parks and gardens or in pots such as on a patio. Even when not in bloom a generally eye-pleasing ground cover is provided by the dark green vegetation.

The new cultivar can be readily distinguished from the ‘Colorado Gold’ cultivar in view of the distinctive blossom coloration. Unlike the new ‘Tangerine Frost’ cultivar, the previously available ‘Colorado Gold’ cultivar produces yellow blossoms with small brown center markings. Also, the ‘Colorado Gold’ blossoms are considered to be of a partially desirable substance.

To the best of the knowledge of the originator the new ‘Tangerine Frost’ cultivar is the first long and substantially continuously blooming Gazania linearis plant having the unique blend of blossom coloration combined with good hardiness to approximately −20° F.

Asexual reproduction of the new cultivar by division was initially carried out beginning on Sep. 15, 2003 at Bridgeton, N.J., U.S.A. At the time of such asexual reproduction the original plant of the new cultivar consisted of two portions of crown tissue that were phenotypically identical to each other. More specifically, a crown portion of the new cultivar was removed from the source plant and the tissue was further divided. It has been demonstrated that the characteristics of the new cultivar are firmly fixed and are well retained following asexual reproduction.

DETAILED DESCRIPTION

The chart used in the identification of the colors described herein is the R.H.S. Colour Chart of The Royal Horticultural Society, London, England. In some instances, more common color terms are provided and are to be accorded their customary dictionary significance. The plants of the new cultivar were approximately one or two years of age when observed during July, 2007 while growing at Bridgeton, N.J., U.S.A. under field growing conditions.

• Plant:
  • • Height.—Approximately 9 cm at an age of one year.
    • Width.—Approximately 34 cm at an age of one year.
    • Foliage.—Form: compact and mounding with leaves growing from a central crown. Quantity: abundant, with a mature plant commonly having approximately 45 leaves per plant. Leaf Size: commonly approximately 1 cm in width on average at the widest point, approximately 2 mm in width on average at the base, and approximately 11.5 cm in length on average. Leaf Shape: linear and slightly spooned. Texture: glabrous no the upper surface and pubescent on the under surface primarily away from the midrib. Color on upper surface: Green Group 139A except at base which is lighter green near Green Group 139C. Color on under surface: midrib commonly is near Green Group 139C with the pubescent remainder being near Greyed-Green Group 190D. Type: semi-evergreen with the plant commonly retaining some green coloration during the winter in U.S.D.A. Hardiness Zone No. 6b.
    • Flower stems.—Approximately 10 cm in length on average and near Yellow-Green Group 145B in coloration.
    • Disease resistance.—Typical of Gazania linearis with no particular disease problems having been observed to date.
