Sarracenia plant predator - home care
Sarracenia - This marsh, rhizome, herbaceous plant is a perennial. It is one of the largest carnivorous plants. Its leaflets, located below, are scaly. Short-hunting leaflets, differing in a rather large size, are assembled in a socket. They rise above the plant itself and the structure in some way resemble an urn with a rather wide opening on top or a tubular jug.
This plant can live only in certain places, since it is endemic. So, it grows and develops well in the Atlantic-North American floristic zone. However, purple sarracenia (Sarracenia purpurea), brought into the marshy areas of Central Ireland, perfectly mastered there.
The flowers are quite large and saturated in color, they have a double perianth. They rise above the plant on a strong peduncle without leaves, which number from 1 to 3 per individual. This plant is characterized by a very large, bizarre-shaped column in the form of an umbrella. On it there are not very large stigmas under the apex of each blade. He has the largest size in purple sarracenia.
There are such species, including yellow sarracenia (Sarracenia flava), which form thickets in swampy areas over the area. Tubular, ribbed jugs-traps of this plant extend almost vertically from a strong horizontally located rhizome. In length, they can be about 70 or 80 centimeters.
In other species, jug traps are smaller and in length they reach from 10 to 40 centimeters. Most of them have a motley color, in which yellow, purple and green predominate. The drawing, located near the entrance to the trap, is painted in the most saturated colors, which makes it very noticeable for insects (even from afar). Each hunting leaf on the shoot side has a pterygoid rim. And its upper part is very similar to the cover. She plays the role of a kind of "umbrella", which is created from the upper blade of the leaf. It slightly closes the entrance to the trap, protecting it from rain drops.
The victims, which are insects, are attracted by the very strong aroma of nectar. And its creator is the nectariferous gland, capable of forming nectar in a relatively large amount. An insect caught on a leaflet slides down the honey path. Inside, on the surface of the walls of such traps, there are special hairs that allow the victim to move exclusively down. Then the victim is trapped in storage rings, and from there she will not be able to get out. After that, it gradually dissolves in the digestive juice. As a result, the plant receives nitrogen, magnesium, calcium, as well as potassium, which is necessary for its vital activity.
Interestingly, various birds consider sarracenia, a kind of feeding trough. They often peck out not yet completely digested insects. There is evidence of scientists who say that in such jugs-traps in several cases, the remains of small tree frogs were found.
There are insects that can live peacefully inside these pitcher traps. The fact is that they are capable of producing special substances that protect the insect from the effects of digestive juice. D. Fish (1976) studied this in more detail, and he writes that larvae of a meat fly, a night moth with its larvae, and a wasp sfex who manage to make their nests there can live peacefully in jugs-traps. These insects destroy most of the trapped victims. And also they significantly damage leaf tissue, from which traps can no longer function normally. As a result, these insects are capable of very much harming entire populations of sarracenia.
There are very decorative species of sarracenia, and in some countries they have been grown for a very long time. The most popular is yellow sarracenia. This is an ornamental perennial plant that has large-sized light orange flowers, as well as juicy, beautifully curved light green trap jugs. If at home they provide proper care and water abundantly, then these plants will feel great even without additional feeding by insects. Sarracenia purpurea is also very popular. Her fragrant flowers smell pleasantly of violets.
In just a few species of such a plant, saracenin alkaloid was found in leaflets, as well as in other aerial parts. It is used in medicine.
Caring for sarracesin at home
In order for this plant to feel good and grow normally, he needs special soil. So, in natural conditions, it prefers to grow on river and lake banks, and also on swamps. At home, it can be planted in the immediate vicinity of the pool or artificial pond. When planting in a container, you will need an earth mixture consisting of 2 parts of perlite, 4 parts of peat and 1 part of building sand. pH should be approximately 5–6.
Feeding should not be in any case, since the introduction of even a small dose of fertilizer can destroy the plant.
How to water
In the event that this carnivore is planted near a pond in the garden, then it should not be watered. It will take the required amount of fluid from the soil. When grown in a container, it is necessary to water rather intensively. The soil must be moistened all the time. In winter, watering should be slightly reduced, since the plant begins a dormant period. During intensive growth, you need to ensure that the flower pot is in the water to a height of about 25 millimeters. In the period from October to April, watering should be carried out 1 time in 7 days. When the transplant is done, you need to increase watering. So, at this time it is necessary to water sarracenia 1 time per day.
Loves the light very much. The plant just needs 8-10 hours a day under bright sunlight. Therefore, it is recommended to place it in the room at the window of a western or southern orientation. It is also possible to provide illumination with fluorescent lamps.
The choice of container or pot
Due to the fact that the plant prefers to grow in moist, well-drained soil, the container or pot must meet these requirements as much as possible.
It is recommended to opt for plastic or glass pots. They should have good drainage holes at the bottom through which excess fluid will flow. Containers made of porous materials are not suitable in this case. This is because they absorb large amounts of water.
This is a fast growing plant. And with proper care, its root system can quickly become closely in a pot. In this regard, the transplant should be systematic and it is better to carry out it in the spring, when the rest period ends. Choose for landing should be a container of not very large size.
Can be propagated by seed. It is recommended to sow them in Petri dishes on peat. The grown seedlings dive into separate small pots. Before sowing, the seeds must be prepared. For this, 1-2 months they should be subjected to cold stratification. Without this, they will not rise. Yellow sarracenia can be propagated by dividing the rhizome. It should be borne in mind that the plant should be quite overgrown. If you divide the bush very often, then the plant is noticeably smaller and may die at all.
Diseases and pests
In the summer, a spider mite or aphid can settle. In winter, rot often forms (botritis mushroom).
