Hybrid Tea rose plant named `Hadlace`

Abstract

A new rose cultivar of the Hybrid Tea class characterized by having medium sized cream, quartered, rosette shaped, flat, fragrant flowers on a bush of moderate vigor. This plant has been designated as `Hadlace`. It will be marketed in the USA under the tradename of `Olde Lace`.

Description

The present invention relates to a new and distinctive cultivar of rose plant of the Hybrid Tea class, which was originated by my crossing ((Pink Favorite.times.(Polly.times.Peace)) as the seed parent with the same pollen parent ((Pink Favorite.times.(Polly.times.Peace)).

Among the novel characteristics possessed by the new cultivar which distinguish it from:

(a) All other cultivars of which I am aware are:

(1) A cream flower with shadings of yellow on inner petals.

(2) Old rose form being quartered, roseette and flat.

(3) Fully petalled.

(4) Very disease resistant.

(b)

Seed parent.--Large, high centered, yellow flowers.

Pollen parent.--Same as seed parent.

Asexual reproduction of the new rose cultivar by budding, as performed at Tulare, Calif. shows that the aforementioned and all other distinctive characteristics come true to form and are established and transmitted through succeeding propagations.

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

The following is a detailed description of my new cultivar, with color terminology in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.). The terminology used in the color description herein refers to plate numbers in the aformentioned color chart, e.g. "53A" is plate "53A" of The Royal Horticultural Society Colour Chart.

Parentage:

Seed parent.--((Pink Favorite.times.(Polly.times.Peace)).

Pollen parent.--Same as seed parent.

Class: Hybrid Tea.

The following observations are made of specimens grown outdoors in Contra Costa County, Calif., in the month of September.
