Hybrid tea rose plant named `Sundel`

Abstract

A hybrid tea rose plant variety producing pink lilac flowers of good form.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct hybrid tea rose variety which was originated by my crossing as seed parent an unnamed and undistributed seedling and as pollen parent the variety known as `Osiana`. The varietal denomination of this new rose is `Sundel`.

SUMMARY OF THE INVENTION

Among the novel characteristics possessed by the new variety which distinguish it from its parents and all other varieties of which I am aware are its attractive pink lilac flower color.

Asexual reproduction by budding of the new variety as performed in Watsonville, Calif., shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations. Other known forms of asexual reproduction may be also used.

COMPARISON WITH PARENTS

`Sundel` is a lavender hybrid tea whereas `Osiana` is a large peach hybrid tea with good production of blooms for greenhouse forcing. The best qualities of `Sundel` are the pink lilac flower color, the high production and the extremely good vase life of this variety, e.g., about 12 days.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying illustration shows typical specimens of the vegetative growth and flowers of the new variety in different stages of development and depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of the new variety, from specimens grown in Watsonville, Calif., in the month of September. The color terminology used is in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.), and refers to plate numbers in the aforementioned color chart. Phenotypic expression may vary depending on light, environmental and cultural conditions.
