Shrub rose plant named `Poulurt`

Abstract

A shrub rose variety producing yellow buds becoming near white to light yellow flowers.

Description

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of rose which was originated by crossing as seed and pollen parents two unnamed and undistributed seedlings of our creation. The varietal denomination of this new rose is `Poulurt`.

Among the novel characteristics possessed by this new variety which distinguish it from its parents and all other varieties of which we are aware are its attractive flowers borne on a healthy and hardy floriferous plant useful in landscaping.

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 employed, such as vegetative cuttings, micropropogation and grafting.

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

Parentage: Seedling.

Seed parent.--Unnamed, unpatented seedling.

Pollen parent.--Unnamed, unpatented seedling.

Class: Shrub.

The following is a detailed description of the new variety, from specimens grown outdoors 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.
