Aldrovanda vericulosa

Aldrovandi in our country can be seen in the central part of the reservoir, in the Caucasus and the Far East.

Aldrovandi has an amazing appearance.It has no roots, and thin weak branching stem, 0.7-1.0 cm in diameter with numerous leaves float freely in the water are from 7 to 9 whorls of leaves, broad flattened petioles which taper upwards and end beam protruding bristles.petiole length longer than the leaf blade, and up to 1.0 cm. The bristles prevent spontaneous closing of the sheet, which may be caused by the movement of water.The number of whorls per plant ranges from 12 to 19, on top of the plant are constantly new whorls are formed, and at the base of the old die.The rate of young whorls in optimal conditions is 1-2 per day.The total length of the plant - 8-15 cm

Leaf blade consists of two symmetrical semi-circular lobes, located at an angle to each other, the width of each share -. 7.5 mm, they are bent along the midrib.Edge seated sharp hairs, which are up to 20 pieces

on each side.Closer to the center of the sheet are the glands that produce a sticky liquid, digestive glands and sensitive hairs.Small aquatic organisms - copepods, ciliates, shoes and others - hurt the hair, and the leaf trap closes for 0.02 seconds.

In the process of photosynthesis release oxygen bubbles that force "victim" to be close to the central vein, where is the bulk of the digestive glands.Traps remains closed from several hours to several days.

At the top of the plant appear graceful wide open pyatilepestnye flowers with white or pinkish petals shiny, the edges of which are decorated with delicate edging ~ pale yellow lemon color.

There are varieties with purple color of the leaves.

Courtship.Aldrovandi - the plant is not for beginners and quite difficult in cultivation.It is grown in aquariums or transparent plastic containers depth of 20-30 cm. It is necessary to ensure intensive illumination.For irrigation use soft water, with a pH of 5,6-6,8, the temperature is maintained at 25-28 ° C, if you want the plant bloomed, it should be raised to 29-30 ° C.

British experts recommend to mix the water with a small amount of peat, and then filter.The amount of nutrients in the water to be small, especially phosphorus and nitrogen content.At the bottom of the container poured a small amount of leaf.

Aldrovandi good "gets" with such species as iris and sedge.Very impressive looks Aldrovandi in wide containers with a large water surface.

Propagation Aldrovandi largely escape portions, lateral branches often break off spontaneously.Under natural conditions, before the onset of a period of rest, at the ends of branches formed wintering buds that survive unfavorable conditions at the bottom of the reservoir.

seeds are formed in very small amounts and have low germination.
