| Abstract: |
A new and distinct variety of rose plant of the Miniature Class is provided which abundantly forms in uniform clusters attractive long-lasting double blossoms having an exhibition-type form of a very stable Chrome yellow coloration. The plant is very bushy and compact, and forms light to medium green vegetation. The blossoms are very slightly fragrant. The plant is well adapted to forcing while grown in small containers, and is particularly well suited for use as a flowering pot plant when grown indoors or outdoors. Additionally, the plant is not particularly affected by cryptogamic diseases. |
| Claim: |
I claim:
1. A new and distinct variety of miniature rose plant characterized by the following combination of characteristics:
(a) forms in abundance in uniform clusters attractive double long-lasting blossoms having an exhibition-type form which are of a very stable chrome yellow coloration,
(b) forms dark green foliage,
(c) exhibits a very bushy growth habit,
(d) is particularly suited for use as a flowering pot plant for indoor or outdoor decoration,
(e) is well adapted to forcing when grown in small container, and
(f) is not particularly affected by cryptogamic diseases;
substantially as herein shown and described. |
| Description: |
SUMMARY OF THE INVENTION
The new variety of miniature rose plant was created by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., theseed parent) was the showbound variety (nonpatented in the United States). The male parent (i.e., the pollen parent) of the new variety was the product of the pollination of the Party Girl variety(U.S. Plant Pat. No. 4,598) by the JUNE LAVER variety(nonpatented in the United States). The parentage of the new variety can be summarized as follows:
The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.
It was found that the new variety of miniature rose plant of the present invention possesses the following combination of characteristics:
(a) forms in abundance in uniform clusters attractive double long-lasting blossoms having an exhibition-type form which are of a very stable chrome yellow coloration,
(b) forms dark green foliage,
(c) exhibits a very bushy growth habit,
(d) is particularly suited for use as a flowering pot plant for indoor or outdoor decoration,
(e) is well adapted to forcing when grown in small containers, and
(f) is not particularly affected by cryptogamic diseases.
The new variety well meets the needs of the horticultural industry. It serves well as attractive ornamentation as a flowering pot plant when grown indoors or outdoors. The flowering is very uniform and the blossoms are relatively stable incoloration upon the passage of time.
The new variety has been found to undergo asexual propagation at West Grove, Pa., U.S.A., by a number of routes, including budding, grafting, cuttage, etc. The characteristics of the new variety have been found to be strictly transmissible bysuch asexual propagation from one generation to another.
The new variety has been named the Lavpet variety.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant parts of the new variety. The rose plants of the new variety describedherein were one year of age were observed during September while growing in containers on their own roots in the greenhouse at West Grove, Pa., U.S.A.
At the left (top) are shown specimens of four buds which illustrate the opening progressionfrom left to right. At the left (middle) are shown specimens of a young stem and a flowering shoot. At the left (bottom) are shown specimens of two main branches. At the middle are illustrated specimens of blooms in progressive stages of opening withthe newly opened blooms being shown at the top and the fully open blooms being shown at the bottom wherein the obverse is shown at the left and the reverse is shown at the right. At the right are illustrated specimens of leaves with three, five, andseven leaflets with the upper surfaces being shown at the right and the under surfaces being shown at the left.
DETAILED DESCRIPTION
The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The terminology which precedes reference to the chart has been added to indicate the corresponding in common terms. Thedescription is based on one year old specimens of the variety which where observed during September while growing in containers on their own roots in the greenhouse at West Grove, Pa., U.S.A.
