Floribunda rose plant named `Devrudi`

Abstract

A floribunda rose plant variety producing single deep pink to light red flowers in clusters.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct floribunda rose variety which was originated by my crossing as seed and pollen parents unnamed, unpatented and undistributed seedlings. The varietal denomination of this new rose is `Devrudi`.

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, single, deep pink to light red flowers that bloom throughout the growing season on a vigorous plant.

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

The seed parent produces deep white flowers, whereas the new variety `Devrudi` produces deep pink to light red flowers. The pollen parent plant is smaller and not as vigorous.

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.
