Miniature rose plant named `Britrick`

Abstract

A new and distinct variety of miniature rose plant characterized by a profusion of exhibition form blooms that ae an unusual combination of colors, consisting of red and light pink with a strong fruity fragrance, on a strong plant with exceptional disease resistance.

Description

FIELD OF THE INVENTION

The present invention relates to a new and distinct variety of miniature rose plant which has been given the international variety recognition designation `Britrick`, and is to be marketed in this country under the synonym `Trickster`.

PLANTS RELATED TO THE INVENTION

The plant of this invention was originated as a result of a planned breeding program and controlled crossing which has as the seed parent the miniature rose cultivar `Jennifer` (U.S. Pat. No. P.P. 5,857) and as the pollen parent miniature rose cultivar `Red Beauty` U.S. Pat. No. P.P. 5,115). The plant of the invention was a selection from the progeny of the stated cross, and has been asexually reproduced by the taking and rooting of stem cuttings. Such asexual reproduction as performed at Lawndale, N.C., has shown conclusively that the characteristic and distinctive features of the plant come true to form and are faithfully transmitted through succeeding propagations, thus establishing that `Britrick` is stable.

SUMMARY OF THE INVENTION

Among the new and novel characteristics which are possessed by this plant, singly and in combination, which distinguish it from its parents and from all other miniature rose cultivars of which I am aware are:

1. Blooms of unusual red and light pink coloration that are well formed, blemish resistant, and show exceptional form and substance;

2. Abundant blooms which are borne singly, and in clusters of up to 5 blooms, on strong stems of from 5 to 7 inches in length;

3. A strong, fruity fragrance;

4. An abundance of glossy, medium green foliage which pleasingly contrasts with an highlights the blooms; and

5. Higher than usual disease resistance to common rose diseases with a higher than usual level of vigor, and growing to a height which is typical of roses of this market class to produce a plant which attractively appoints the home garden while providing cut flowers of exhibition form and quality.

BRIEF DESCRIPTION OF THE DRAWING

The single sheet of the accompanying drawing is a photographic illustration which shows foliage and typical specimens of the flowers of the new variety in different stages of development. Colors illustrated are as accurate and true as is reasonably possible to attain in color illustrations of this type. In this regard, it should be noted that the apparent flecking on the upper surface of the petals is not a characteristic feature of the plant and may be due to reflectance. However, some flecking does appear on the under side of the petals as they begin to open.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT
