Description

The invention relates to the vegetative propagation of the mother plant of a hydrangea variety, which from the previously known hydrangea varieties thanks to a new, clear and permanent color scheme of the Flowers differs. The hydrangea also has vigorous growth and normal flowering ability in the months of April to July. Its flowers are dark red in color with a shiny, velvety sheen.

Among the hydrangea varieties used by the horticultural industry to grow flowering plants Are available, be it for early flowering or at normal times or late, the red varieties are in the minority. It is not one of these hydrangea varieties succeeded in asserting itself in the special cultures in the same way as z. B. the pink variety »Merveille« and the white variety »Soeur Therese«. This is due to the fact that the for large The species available to crops were either unattractive in color or inconsistent were in color or showed defects in growth - just to name the most common defects.

The breeder, who had a large number of varieties at his disposal, engaged in several Years with the creation of new varieties by means of hybrid breeding, the characteristics of which match those given above came close. After making a strict selection and singling out all those varieties, who did not seem suitable to him as possible parents of a new breed as he had in mind, he chose No. 140, called "Vulcain", as the female part or among the retained varieties Seed carrier and the No. 107 as the male part to remove the pollen. From these two Cultivars were carefully selected for seven plants each. After emasculation of the fertile Flowers of No. 140 became the pollen of No. 107 on the style of the for several days first-mentioned variety transferred.

After this lengthy work of thinking through and directing fertilization, a great one developed Number of fruits from which large numbers of seeds have been taken, their cells necessarily are biologically different from those resulting from natural fertilization, because they came from the fusion of two cells of different origin.

From the sowing of these seeds, two hundred and six young plants emerged and grew biologically as well as in their external appearance differed from each other. According to normal culture outdoors throughout the summer they became vegetative propagation of the mother plant a hydrangea variety

Spent in the greenhouse at the end of January. The majority of them, i.e. H. exactly one hundred and eighty-six Plants, bloomed April 10-30. They each represented a new variety.

A strict selection set in here, and the observations were only continued six varieties retained. Breeding was continued with these plants. They were cut back to cause the formation of young shoots for the first offshoots, which are used to form roots further treated. The breeder now had a sufficient number of plants from these six varieties to observe their behavior and characteristics during a second flowering. The growth over the next summer was very favorable, and in the fall all the plants gave birth abundant buds.

They were returned to the greenhouse at medium temperature in mid-February, and the bloom started at the end of April. The majority of the six species were very beautiful, but one was special Beauty from. It was particularly beautiful in color, dark red with a shiny velvet look Shimmer of the fully bloomed flowers. The flowers were large, on a small, very stiff Sessile flower stalk. The rather low plant with thick, very stiff stems and a bright dark green Foliage makes a very handsome, well-done impression.

of all other plants retained as the only ones to determine whether the other properties are suitable for making them interesting to the horticultural industry allow.

A series of tests was carried out to determine whether the cuttings easily take root, and about the formation of new shoots after the branch ends have been pinched off, the resistance against diseases, the quality of the bud formation and its persistence and also its suitability for Verify endurance of summer heat during flowering.

The results were entirely satisfactory and underscored the importance of this new hydrangea breed with a view to their use in the horticultural industry.

The following is a detailed description of the new hydrangea:

CLASS Hybrids of Hydrangea Hortensis.

PLANT
Height:

With summer growth 6 to 10 cm.

Growth:

After the tips of plants with several flowers have been pinched off, the plant has tufts from three to eight branches that diverge from below in a fork-like manner. The plant makes a stocky impression, and its growth is strong, but it has short, albeit thick wood, especially in plants with only one stem, so-called single-blooded ones Plants. Bud formation is very regular and its persistence is very satisfactory.

LEAVES

40

Opposite, stalked, with an axilla at the base of the petiole; Length of stem 3 up to 5 cm with fully developed leaves. The petiole is with a spread over the whole length extending concave groove and runs towards the top.

Whole leaf blade tapering to the tip, regularly toothed, hairless, dark green (Seguy 426) on top, lighter green (Seguy 372) on the bottom. The hue becomes lighter on the oldest leaves, i.e. H. with such leaves, the furthest from the inflorescence; Top side Seguy 372, bottom side Se "guy 352.

Axial rib extends the petiole to the tip of the leaf. Side ribs do not branch on each side of the leaf blade from the same point on the midrib. Goes from the side ribs a fairly large number of strips extending into the next minor rib in a more or more less broken line.

The leaves are serrated a few centimeters from the petiole. Teeth pretty much in the lower quarter far apart, towards the center and tip of the leaf, they are more closely approximated. The teeth are fairly rounded at the top, measuring around 2 to 4 mm at the base and are 1 to 3 mm long.

The shape of the leaves is approximately oval, but not with the fully developed leaves very far from the round shape. In the young leaves and in those of the summer crops the shape remains more oval. The parenchyma goes to the base of the leaf on both sides of the stem at the same height. It is not very wide and distant beyond a few centimeters progressively from the axial rib, in order to finally come back down to a fine one Taper tip.

INFLORESCENCE

Terminal, compound umbels, spherical. The number of flowers varies, depending on Umbel between thirty and seventy, sometimes more; on a sturdy and stiff stem of Sitting 2 to 3 cm in length.

FLOWER STEM

Very strong, thick, stiff, of cylindrical diameter; the annual shoots green, irregular spotted. Spots ovate 2 to 4 mm long and 1 mm wide, purple in color (Seguy III), sometimes with a center in the green color of the stem. They are irregular arranged at a distance of 4 to 12 cm from each other.

KNOTS The knot does not form a round elevation around the stem, but a slight thickening on the stem Attachment of axillary shoot and petiole. The nodes are 2 to 4 cm apart, and each branch bears four to six pairs of leaves. The distance on the flower stalk is from the first to the third knot 3 to 10 mm, from the third to the fourth knot 3 to 5 cm, from the fourth to the sixth knot 5 to 7 cm.

FLOWERS Barren flowers:

Very numerous, made up of the following parts: four petal-like sepals, sometimes five, with very irregular margins and weakly serrated, at their free end slightly curved; five to seven nerves distributed differently over the petal, the middle one most developed. Lateral nerves branch off from the main nerve and from the other radiating nerves. The sepals are fan-shaped, length 2.5 to 4 cm, width 3 up to 4 cm. Very often the sepals have small round ones on their upper side when they are fully in bloom or oval swellings 1 to 3 mm in diameter in the round shape, in the oval shape, some reach a length of 3 to 5 mm. Color not even, becomes very dark. Upper side of uneven color, darker in the peripheral zone and darker in the area the approach becomes lighter; Seguy 47 or 52 for the darkest zone, Seguy 53 for the lightest -Zone. Almost evenly tinted on the underside, lighter than that of the top, Seguy 53.

Four small petals of 2 x 2 mm, oval, very light purple (Seguy 60), some colorless, at the edge against the cap-shaped center

10

too bent back; eight stamens, filaments and anthers colorless when ripe, but of very light green when the stamens are still enclosed in the petals; Jumping up in elongated shape; curled up from the outside in; Pollen grains spherical; Ovary medium (semi-infere) with three short styluses, colorless on the edge, violet-colored near the colorless stigmas.

Fertile flowers:
Very low number; Calyx with green sepals 2 x 2 mm, crown with five petals four times 2 mm, pink on the bud, violet (Seguy 618) on the open flower. Pollen grains spherical, ovary medium-sized (semi-infere), three short styles, colorless at the base, pinkish-purple near the three colorless stigmas.

DEVELOPMENT

The rooting ability of the cuttings is very good; Roots are finer and longer than the ones known varieties. The cuttings as well as the fully grown plants show a rather low one and stocky but strong growth. The branching of the young plants after Stranding is very good. Bud formation is very good in autumn and starts quite early. Durability in winter very satisfactory.

This new variety is not suitable for forcing a winter flowering, but its first flowering in the middle April is very good. However, it is well suited for late blooming in June and July; the Flowers resist the summer heat well in contrast to the great majority of them known species. It takes on the blue color, but in a very dark tone.

RESISTANCE Very satisfactory against cold and also against the nematode (anguillule) and against various diseases. During the summer bloom the resilience of the flowers is particularly great and their behavior particularly in the heat cheap.

The pictorial representations in FIGS. 1 to 8 show individual features which can be used for identification of the new hydrangea variety: Fig. 1 shows part of the flower stem,

Fig. 2 shows a leaf from the middle part of the flower stem,

3 shows a leaf at the top of the flower stem,

Fig. 4 shows a leaf on the lower part of the flower stem, Fig. 5 shows a fully open flower,

6 shows an open flower in the middle stage,

7 shows an open flower in the initial stage,

Fig. 8 shows a flower at the start of opening;

Fig. 9 shows an overall picture of the plant.

To distinguish it from other hydrangea varieties, it was given the number 232. It will be sold under the name »PIRATE«.

The hydrangea thus has the following appearance:

It is richly branched, of sturdy growth, rather low in normal culture, has thick and hardy wood, and their foliage is a very dark, brilliant green. The shape of the The leaves are in the middle between oval and round, almost serrated from the petiole. The umbels are exposed Flowers together, consisting of petal-like, dark red sepals, of round shape and arranged like a fan.

From a biological point of view, this new variety has the ability to flower late because of the summer heat well tolerated. The flower buds form fairly early and hold up well. The plant is completely resilient against the various diseases, the cuttings take root easily. She takes the blue one Color on but a very dark shade. The shelf life of the flowering plants in the room is very long.

The traits and characteristics of this new variety of hydrangea are asexual faithfully transferrable, allowing any industrial propagation of this variety by cuttings is guaranteed.
