Bell Vine - Cobaea scandens

Climbing plants are very popular with garden owners. They serve as privacy screens from the prying eyes of the neighbors. Climbers are often used for the privacy screen. The bell vine belongs to the family of climbing plants and convinces in the summer with an evergreen growth. The bell vine is also known under the name Krallenwinde or bell winds. It is a climbing plant whose origin was recorded in Mexico. The Cobaea scandens, as the Latin name of the climbing plant is, serves equally well as a climbing plant on facades or garage walls. For a cultivation in a pot, the fast-growing plant is also suitable. The stature height is a pot much smaller. Cobaea scandens is one of the plants that need a climbing aid to find the right direction. In summer, the bell vine enchants with purple leaves and a sweetish scent reminiscent of honey. The climber can reach a height of four meters quickly.

Sowing and propagation

Sowing is the cheapest in spring. For the seeds to germinate, they need a warm place. Well suited is a place on the windowsill where it is bright and warm. You can also grow the seeds in a greenhouse. Put just three seeds in a small pot. Once the seedlings have a height of 10 cm, they are trimmed. Repeat this process once the height of 10 cm has been reached. Only then do the seedlings get a climbing aid in the form of a thin bamboo stick. Once the icy saints are over, you can put the seedlings in their designated place. To multiply the Cobaea scandens, remove some seeds from the plant after flowering. These can be sowed as described. However, you can also buy the seed in a garden shop.


The plants should be brought into the open air only after the ice saint. Note that the floor should have permeable properties to prevent waterlogging. The young plants are placed in the ground, the hole should be about twice as large as the root ball. Also note that the plant will not tolerate frost and should therefore hibernate in the greenhouse or conservatory. If you want to plant the bell cherry directly in the garden, you should consider the wintering. Alternatively, you can leave the plant in the garden and risk the death of the plant. In the spring, the plant can be sown again.


If you want to leave the bell in a pot, it is advisable to repot the plant once a year, but at the latest when the roots grow out of the pot. Now use a 3 to 4 cm larger pot to give the plant enough space. Keep in mind that the bell-ring can be very heavy, which is not very suitable for standing on a balcony.


For a fast growth the plant needs a lot of water. She gets along less well with dry phases. In the summer, the Cobaea scandens should be sufficiently poured daily. In addition, brown leaves are removed at regular intervals. Although the bell vine prefers a nutrient-rich soil, you should nevertheless proceed very sparingly with the addition of fertilizers. If it comes to an overeating, the plant stops the flowering and is literally blooming lazy.


The bell vine needs a sunny location for good growth, which is also well protected from the wind. The soil should be rich in nutrients and permeable. Waterlogging is essential to avoid, as this would contribute to the plant's entry. If you want to cultivate the Cobaea scandens in a pot, make sure that the pot is not too small. So that the bell vine in the pot can grow well, you should lay out the lower area with a little gravel. This ensures that the excess irrigation water can drain better and no waterlogging forms. Moreover, the plant does not require much care.

to water

In the summer months the Cobaea scandens needs a lot of water. Especially in June, when the plant makes the first flowers, you should not be sparing with water. In the cooler months it is sufficient if the Cobaea scandens receives enough water two to three times a week.


Avoid over-fertilizing, as the bell-vine will otherwise become lazy. She immediately stops the flowering. It would be best if you could add some compost to the plant once a year. Other fertilizers are then no longer necessary.

To cut

If you want to let the plant hibernate, it makes sense to cut them properly before the start of frost. If the bells turn out to grow too fast, you can easily cut the Cobaea scandens into shape at other times as well.


Before the Cobaea scandens is brought to a warm place for the winter, it is advisable to cut the plant down to 50 cm. Since the bell vine comes from Mexico, it does not tolerate frost and should therefore winter in the greenhouse. You can also have the Cobaea scandens overwinter in the apartment or conservatory. Choose a sunny and very bright location. Constant temperatures of 10 to 15 degrees are optimal. Water the plant regularly even in winter.

Diseases and pests

As a rule, there are no special diseases of the plant. Young plants are often visited by snails. But as soon as the plants get older, the snails let go of you and make their way. During wintering, spider mite infestation may occur. Also aphids love the climbing plant very much and like to infest them. Against spider mites and aphids it helps to spray the plants with a soapy water. This process should be repeated until there are no more spider mites and / or aphids.


The flowers appear from July to October and show first white or yellow-green and take later a violet-bluish color. The bell vine branches very strong and becomes in our latitudes up to 2 meters high.
The plant likes to be sunny and protected and prefers a nutrient-rich and humus-rich soil. Slightly shady locations are still accepted, but they will not grow as abundantly. Locations on the east and west sides are ideal. When using unit earth, mix in about 1/3 sand. The bell vine should always be kept slightly moist. Since it grows very fast, it needs a lot of water. For this purpose, it must be sufficiently supplied with nutrients. It is ideal if you incorporate horn chips into the soil before planting. Too nutrient-rich locations can minimize the flowering willingness. In order for the plant to be well-branched and richly flowered, the shoots need to be regularly peppered.

The bell-vines are increasingly grown by sowing, from mid-March in the greenhouse or 2 seeds in a nutritious potting soil 8 to 10 cm large pot. At 18 degrees Celsius and uniform humidity, they are cultivated further. One to two pruning promotes branching and dense growth. If no frost occurs, the young plants can be placed in nutrient-rich, loose garden soil. The planting distance should be 30 cm.
The bell vine needs solid climbing aids around which the tendrils can wrap. It is very suitable as a visual, wind and sun protection.
If you want to keep the bell vine as a container plant, you must ensure a sufficiently large planter. In the bucket, the plants are usually not so big.
