Modern tea-hybrid roses arose as hybrids of ancient tea and remontant roses with the involvement of other species and varieties of roses. They are grown as decorative plants in private or public gardens. They are one of the most popular and widely cultivated groups of flowering plants, especially in temperate climates. An enormous number of garden cultivars have been produced, especially over the last two centuries, though roses have been known in the garden for millennia beforehand. While most garden roses are grown for their flowers, often in dedicated rose gardens, some are also valued for other reasons, such as having ornamental fruit, providing ground cover, or for hedging. The cultivars are classified in a number of different and overlapping ways, generally without much reference to strict botanical principles. Taking overall size and shape, the most common type is the bush rose, a rounded plant from 2 foot up to about 7 foot tall, above which height roses generally fall into the "'climbing and rambling'" class, the latter spreading wider; support is needed for these. There are also miniature roses, generally small bushes, and low sprawling ground cover roses, both up to about 15 inches tall.

SUMMARY OF THE VARIETY
The rose variety ‘Delstriro’ / ‘Red Intuition’ exhibits the following combination of characteristics:
Forms green mature wood, displays a bushy growth habit, and forms attractive long lasting clear red striped with darker red double flowers.
Forms semi-vigorous to vigorous vegetation, produces flowers in abundance, exhibits the ability readily to be forced, and is resistant to diseases.
Produces relatively straight stems, rigid and substantially straight peduncles, has excellent ability to be forced under greenhouse growing conditions, and a good vase life for the distinctive clear red striped with dark red blossoms.
The rose variety ‘Delstriro’ / ‘Red Intuition’ underwent an asexual propagation and can be readily reproduced by conventional routes, such as budding (i.e., eye grafting), the rooting of cuttings and tissue culture. This asexual reproduction by budding as performed at Hyéres, France, has demonstrated that the characteristics of the new variety are stable and are strictly transmissible from one generation to another.

ORIGIN OF THE VARIETY
The rose variety ‘Delstriro’ / ‘Red Intuition’ was discovered in a greenhouse at Hyères, France, during 1999 and is a spontaneous mutation of unknown causation of the ‘Delego’ / ‘Belle Rouge’, a Hybrid Tea rose variety from Delbard, 1996. Had this variety not been discovered and preserved it would have been lost to mankind. There is no information about the origin of the name of this rose.

COMPARISON WITH PARENTS
The ‘Delstriro’ / ‘Red Intuition’ can be easily distinguished from other varieties as well as from the parent variety ‘Delego’ / ‘Belle Rouge’ by the following characteristics:
While the parent ‘Delego’ / ‘Belle Rouge’ rose variety display dark red flowers without the stripes, the flowers of ‘Delstriro’ / ‘Red Intuition’ have striped red flowers.

FLOWERING
The variety has very good, repeated flowering, blooms abundantly and nearly continuously. In a greenhouse conditions the variety is able to produce flowers year-round.
Flower bud:
The flower buds have ovate shape in longitudinal section just before the opening of the sepals. Before the calyx breaks the bud has length of about 2.8 to 3.1 cm, with an average length of approximately 3 cm.
The colour of the bud as calyx breaks is dark red striped with dark purple red. The length of the bud after the calyx breaks is about 3.8 to 4.5 cm, with an average length of approximately 4 cm. The colour after the calyx breaks is dark red striped with dark purple red.
Number of flower buds is generally one per stem when grown under a greenhouse condition; however, sometimes during forced culture an axillary eye or eyes below the flower develop to form 1 or 2 flowers.
The peduncle is erect, stiff, has medium green colour with some small hairs. The length of the peduncle is about 8.5 – 11.5 cm, with an average length of 10 cm.
There are 2 sepals commonly possess no extensions, and 3 sepals commonly possess medium to strong extensions. The extensions are denticulate and commonly are long to very long. The sepal length is about 5 – 7 cm. The colour of the sepals is medium brown green on the upper surface and dark brown green on the under surface.
Bloom:
The flowers of ‘Red Intuition’ are medium to large, the diameter of the open flower is approximately 10 to 12 cm, and approximately 11 cm on average, with a standard deviation of 0.5 cm. The flowers have high-centered, an irregularly rounded shape when viewed from above. They are very double, with flattened convex at the upper part when viewed from the side and flattened convex to convex at the lower part when viewed from the side.
They last of a plant long – about 7 to 10 days under normal growing conditions. When cut and placed in a vase, the flowers commonly last approximately 5 to 6 days.
Petals:
The number of petals on a flower is about 31 to 39, with an average of approximately 36. The length of the petals on the second row from the outside is about 5.5 - 6.5 cm with a mean of approximately 5.9 cm, and a standard deviation of 0.4 mm; the width is approximately 5.5 – 6.9 cm with a mean of approximately 5.3 cm, and a standard deviation of 6 mm. The shape of the petals of the first row is commonly exhibits a broad ovate configuration, the undulation of the petal margins is average, and the reflexing of the margins is average.
The following description of a colour of a nearly fully open flower was made while observing a rose which had been undergoing opening for three days:
The petal colour in the middle zone: on the inner surface is medium red striped with dark purple red; and on the outer surface is red pink with darker striping of dark red or red pink.
The colour of the petals on the marginal zone on the inner surface is medium red striped with dark purple red, and on the outer surface is red pink with darker striping of dark red and red pink.
The basal spot on the petals is small in size and can be absent when the plant is grown outdoors. The color of the spot in the inner side is medium yellow and on the outer side is light yellow.
Petals drop off cleanly when the flower fades.
Fragrance:
The fragrance in this variety is very slight, Tea.
Reproductive parts:
The number of stamens per flower is about 136 and they are somewhat regularly arranged around the styles.
The filaments are medium in length, not all possess an anther. When the flower is partially open they have dark yellow and medium yellow orange colour; and when the flower is fully open the colour changes to pink and medium yellow.
The anthers are medium sized, all open at approximately the same time, and the immature coloration is medium yellow orange.
The pollen is sparse in quantity and has medium yellow orange colour.
The number of pistils is approximately 147.
The styles are medium long and have red pink colour.
The stigmas are light yellow orange, and generally are present at the same level as the anthers, but a few anthers may be higher.
Hips are rarely formed and are funnel-shaped when formed and are approximately 23 mm in diameter.
The seeds have not been observed up to date.
