Hybrid tea rose plant named `Hilaroma`
A new and distinct variety of Hybrid Tea rose plant is provided which abundantly and continuously forms attractive bicolored blossoms. The blossoms are Naples Yellow and strongly edged with Venetian Pink on opening and turning to Neyron Rose when fully open. The blossoms exhibit a strong spicy fragrance. Such blossoms are long lasting and their cleaning ability is excellent. The plant exhibits a bushy growth habit, very vigorous vegetation, very leathery foliage, and is particularly well suited for growing in parks and gardens. Also, the new variety is not particularly affected by cryptogamic diseases.
Latest The Conard-Pyle Company Patents:
The new variety of Hybrid Tea rose plant was created by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) of the new variety was the Pristine variety (U.S. Plant Pat. No. 3,997), and the male parent (i.e., the pollen parent) was the Friendship variety (U.S. Plant Pat. No. 4,284). The parentage of the new variety can be summarized as follows:
Pristine.times.Friendship.
The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.
It was found that the new variety of Hybrid Tea rose plant of the present invention possesses the following combination of characteristics:
(a) forms in abundance on a continuous basis attractive very fragrant long lasting bicolored fully double flowers which are Naples Yellow and strongly edged with Venetian Pink on opening and turning to Neyron Rose when fully open,
(b) exhibits a bushy growth habit,
(c) exhibits very vigorous vegetation,
(d) forms foliage which is very leathery, and
(e) is not particularly affected by cryptogamic diseases.
The strong spicy fragrance of the blossoms is particularly noteworthy. The disease resistance of the new variety is above average.
The new variety well meets the needs of the horticultural industry for a number of uses and is particularly well suited for growing as attractive ornamentation in parks and gardens.
The new variety has been found to undergo asexual propagation at Richmond, Ind., and West Grove, Pa. U.S.A. by a number of routes, including budding, grafting, cuttage, etc. The characteristics of the new variety have been found to be strictly transmissible by such asexual propagation from one generation to another.
The new variety has been named the Hilaroma variety.
BRIEF DESCRIPTION OF THE PHOTOGRAPHThe accompanying photograph shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant parts of the new variety. The rose plants of the new variety were three years of age and were observed during September while budded on Rosa froebelii understock and growing outdoors at West Grove, Pa., U.S.A.
From left to right on the top row are shown a specimen of a young shoot, a specimen of a leaf with three leaflets--plan view--upper surface, a specimen of a floral bud before the opening of the sepals, a specimen of a floral bud at the opening of the sepals, a specimen of a floral bud at the opening of the petals, and a specimen of a flower during the course of opening.
From left to right on the second row are shown a specimen of a leaf with five leaflets--plan view--under surface, a specimen of a leaf with five leaflets--plan view--upper surface, a specimen of an opening flower--plan view--obverse, a specimen of an opening flower--plan view--reverse, at the top a specimen of a floral receptacle showing the arrangement of the stamens and pistils, and at the bottom a specimen of a floral receptacle showing the arrangement of the pistils (stamens removed).
From left to right on the third row are shown a specimen of a leaf with seven leaflets--plan view--under surface, a specimen an open flower--plan view--obverse, and a specimen of an open flower--plan view--reverse.
From left to right on the bottom row are shown a specimen of a main stem, a specimen of a flowering stem, a specimen of a fully open flower--plan view--reverse, and a specimen of a fully open flower--plan view--obverse.
DETAILED DESCRIPTIONThe chart used in the identification of the colors is that of the Royal Horticultural Society (R.H.S. Colour Chart).
