Drosera binata

Origin

It is common on the east coast and south-east of the Australia. Is sometimes in Tasmanie and New Zealand. This plant pushes in peat bogs or in wet moors and in general in a subtropical Climat.

Description

Hardy perennial, terrestrial, herbaceous, robust of which there exist several forms and varieties. Its size varies between 30 and 50 cm height.

Sheets: They are divided into two parts giving to the Feuille the form of a Y. Seule this last part, the Limbe carries hairs provided with glands which produce sticky droplets. The Pétiole is smooth and does not comprise glanduleux hairs. The new sheets form, with starting, a sling comparable with that of the ferns. The sheet is held completely when it reached its adult size. With a good sunning, the end of the sheets takes a reddish color.

Flowers: high floral pole the 40 cm is vigorous, and presents two groups of flowers. They are of a pure white and of a diameter from 2 to 3 cm, they are with the number of about thirty. There exists a subspecies with Fleur S pinks. Flowering takes place of the month of May in the month of August.

The many seeds are contained in an almost round capsule. They fine and are lengthened, of color brown clearly, with a Membrane being spread out each side.

Culture

It will be necessary to use a pot of 13 cm at least if one wants to have a beautiful plant. Repottings will take place with the Printemps or the beginning of the be. This robust plant can undergo short periods of freezing, once installed well.

However in Winter, the Compost will have to be only wet and it is advised to remove the saucer under the pots. In the areas with Winter soft, this plant could be installed outside all the year in a mini-peat bog.

Substrate: 70% of fair Peat + 30% of Calcareous Sand not .

Temperature: Out-freezing the Winter and of 20 with 35°C the be.

Hygroscopy: from 50 to 70%.

Watering: maintain the ground wet all the year by means of the presence of a saucer under the pot, reduce and remove in Hiver.

Exposure: the full sun is appropriate to him perfectly, although you can place it in a place a little less sunny.

Parasite (S) and disease (S): the Puceron S often cause damage with the starts-up and the floral buttons. It is necessary to take care to eliminate them as of their appearance. This robust plant does not pose practically any problem in culture.

Multiplication

By sowing: Although Drosera binata flower abundantly, it is not very easy to obtain seeds, contrary to other Drosera. I tried on several occasions to pollinate flowers manually, but without success so far.

However if seeds are obtained, they immediately will not be sown. One will make them winter in the bottom of a refrigerator to sow them with the Printemps. The very fine seeds, will practically not be buried. They will raise without problem at the end of approximately three weeks. One will use a Compost made up of Tourbe and Sable.

At the beginning, the sheets of the young seedlings do not have the typical shape of the adult plants. The young seedlings form initially a rivet washer like all other Drosera, the " frondes" and the sheets drawn up in form of Y, appear only a Mois later. It is only as from this moment that one will be able to mend the young seedlings in their final pot.

By divisions of tufts: the tracing root of Drosera binata often gives rejections to the Printemps. For this reason the plant needs much space.

The resumption of the rejection does not pose a problem, if there is care to detach it well from the stool by making a clear cut using a tool edge. The best moment to carry out this operation is the end of the Printemps, when the rejections are sufficiently strong to be transplanted. Indeed, if those do not have enough roots, there is little chance that they begin again.

By cuttings of roots: Of the ends of roots from 2 to 3 cm begins again very easily. One will horizontally pose them on a mixture of Tourbe and with Sable and one will slightly cover them with peat or Sphaigne chopped. The adventitious buds will appear at the end of 4 to 5 weeks.

Contrary to sowing, the cuttings of roots will immediately give sheets in the shape of fork. There too, it will have to be waited until the young seedlings are well started to carry out transplantation in the final pots.

By cuttings of sheets: It will be necessary to take young adult, robust sheets and in good health. The sheets will be placed at choked in small boxes covered with a Vitre. The sheet will be maintained plated on the ground by small arches.

The best moment to try the cuttings of sheets is the end of the Printemps when the Température starts to be a little higher. One will gradually accustom the starts-up to the great outdoors, by entrebâillant the Vitre a little more each day.

Observations

The characteristic of this Drosera is to have sheets fourchues. There are several varieties according to the number of divisions. It is a rather large plant which can have some 25 cm length sheets and robust roots: large and deep pot here is very recommended (at least 18 cm).

Of frail aspect, several plants by pot will have better pace than only one. It is relatively easy of culture, appreciates the full sun and a winter rest except freezing is advised, during which the sheets disappear. The seeds also have a good rate of Germination.
