1 Claim. (Cl.-4761) The present invention relates to a new and distinct variety of rose plant of the hybrid tea class, which was originated by me by crossingan unnamed and unpatented seedling of Charlotte Armstrong (Plant Patent No. 455) X Applause (Plant Patent No. 829) with the variety Ena Harkness (unpatented) 7 As a result of this breeding, I have produced a new rose variety which is particularly characterized as to novcity by the following distinctive features which, considered together, represent a new and unique combination in a rose of this class:

.(1) An upright, vigorous and bushy habit of growth similar to that of the variety Etoile de Hollande (unpatented), but less sprawling than the habit of the variety Crimson Glory (Plant Patent No. 105);

(2) Relatively large, beautifully formed and gracefully refiexed blooms which are similar in general shape (3) Strong bloom-supporting neck;

(4) Rich, velvety, dark red or crimson general color tonality of the flowers, said color being much darker than that of the blooms of"Ena Harkness; and

('5) Strong fragrance of deep Old Rose (centifolia) comparable to that of the variety Crimson Glory.

Rose experts who have observed my new variety consider the same as constituting a new break in red roses, viz., a very fragrant dark red rose with a strong neck capa'ble of providing good support for the relatively large bloomssomething that has not heretofore been available in this color class. Moreover, the new variety is "suitable for both garden planting and for use as an exhibition rose when given good cultivation. It is definitely distinguished from its parents as well as from all j other'varieties of which I am aware, and asexual reproductionther'cof by budding, as performed at Roseburg, ;-Oregon, shows that'the foregoing characteristics and different stages of development and as depictedin color 7 I 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 the new variety, with color terminology in accordance with Robert F. Wilsons Horticultural Colour Chart,'ex-cept where general color terms of ordinary dictionary significance are obvious Type: Bush; outdoor, seedling;. hardy to at least 5 above zero; for out flowers and for garden decoration.

Insect resistance-Inherent vigor quickly overcomes 3 severe, slug damage tov shoots and canes, but no,

unusual resistance. to insect attacks has been established.

Growth:

Thorns-many; ranging from 37 on 15 stems to f 5 77 on 24" stems; medium large x at base and from V2" to Va" in length); hooked downwards; color light tan at maturity.

Prickles-few; colorgrey green. Hairs-very few; color-grey green.

Branches.Co1or-dull grey green at maturity; with New sh0ots.-Colorfrom bright brownish red to near Garnet Brown, Plate 00918/1, p. 192, similar to color of young foliage. Thorns-moderately few; medium long; hooked downward; with narrow, slightly oval base. Prickles-few; colorreddish tones near Garnet Brown, Plate 00918/1, p. 192. Hairs--very few; colorreddish tones.

I claim:

A new and distinct variety of rose plant of the hybrid tea class, substantially as herein shown and described, characterized particularly as to novelty by its upright, vigorous and bushy habit of growth, its relatively large, beautifully formed and gracefully reflexed blooms, its

strong bloom-supporting neck, the rich velvety dark red general color tonality of its blooms, and the relatively strong, deep Old Rose fragrance of the blooms.
