HOW TO GROW AND CARE FOR OUR PLANTS
also known as
The Trachelospermum they are very popular because they resemble jasmine but on the contrary they are much more rustic and easier to grow.BOTANICAL CLASSIFICATION
Species: see the paragraph on "Main species"
The genre Trachelospermum of the family of Apocynaceae includes numerous species native to China and Japan but of which only the Trachelospermumjasminoidesit is well known and cultivated.
These are shrubby, evergreen, climbing plants with semi-woody, flexible and milky stems from which numerous aerial roots develop. Trachelospermum they are leathery, opposite, whole, oval and with very marked veins and generally of an intense green color.The flowers are starry, white in color and form in axillary or terminal tops, they are very fragrant and are very reminiscent of jasmine flowers.
The Trachelospermum they are very luxuriant plants that produce very showy and fragrant patches of green, particularly decorative.
There are about 20 species in the genus Trachelospermum but the most cultivated is there TRACHELOSPERMUM JASMINOIDES (OR RYNCOSPERMUM JASMINOIDES) plant also known by the name of star jasmine (name deriving from the particular shape of the flowers) or false jasmine, characterized by very intense green and oval-shaped leaves that grow up to 8-10 m in height.
At the end of spring-beginning of summer it produces very fragrant white flowers whose corolla forms a tube which contracts in the lower part, widening to form five petals.
These are plants originating from China but now very widespread a little everywhere in the temperate climate regions.
There are several cultivars among which we remember Trachelospermum jasminoides'Variegatum' with leaves streaked with white; Trachelospermum jasminoides 'Wilsonii' with leaves that turn red in autumn.
It is also known by the names of ricosperno or recospermo.
The Trachelospermum they are fairly simple plants to grow and require no special attention or care. They can be grown both in pots and in open ground, to adorn and perfume a corner of a garden.
They can be grown in full sun or partial shade. Although they are acoustic plants, they do not like wind and frost, therefore where temperatures drop considerably during the winter period, it is necessary to repair them during this period.
If grown in pots it would be advisable for them to be brought outdoors with the arrival of summer.
As a climbing plant the Trachelospermum it is widely used to cover walls and fences, otherwise it is advisable to support the stems with stakes, racks or nets.
It is a plant that is often preferred to jasmine because it is much more rustic and less demanding.
There Trachelospermum it needs regular watering from spring and all summer taking care not to let the soil dry out. During the winter, reduce watering and wait for the soil to dry on the surface before proceeding with the next watering.
TYPE OF SOIL - REPOT
There Trachelospermum it is not particularly demanding in terms of soils even if it prefers neutral or slightly acid soils but in any case absolutely not calcareous. If raised in pots, add a little peat to the mixture.
They are plants that do not like water stagnation therefore make sure that the soil is well draining.
Starting from spring and throughout the summer, it should be fertilized regularly every two weeks by diluting the fertilizer in the watering water.
It is advisable to use a fertilizer that in addition to having macroelements such as nitrogen (N), phosphorus (P) and potassium (K) also has microelements such as iron (Fe), manganese (Mn), copper (Cu), zinc (Zn), boron (B), molybdenum (Mo), all important for proper plant growth.
Pruning should be done regularly to reinvigorate the plant. Usually for the Trachelospermum the operation is carried out in spring, removing the most vigorous branches.
It is also advisable to regularly trim the vegetative apexes to stimulate bush growth and eliminate green leaves in variegated cultivars.
Flowering begins in late spring-early summer.
It is preferable to promptly remove the inflorescences as soon as they wither.
The multiplication of the Trachelospermum it can be done by cuttings.
10-15 cm long cuttings are taken from March to September from the lateral shoots, taking care to leave a portion of the bearing branch. The cut must be done obliquely as this allows to have a greater surface for rooting and avoids the accumulation of water on this surface.
To cut, use a razor blade or a sharp knife to avoid fraying fabrics and take care that the tool you use for cutting is clean and disinfected (preferably with a flame) to avoid infecting the fabrics and disinfect each cut.
After removing the lower leaves, arrange the cuttings in a composite of peat and sand in equal parts.
The box or vase is then covered with a transparent plastic sheet (or a bag with a cap) and is placed in the shade and at a temperature around 18-20 ° C, taking care to keep the soil always slightly moist, watering without wetting the cuttings. in rooting with water at room temperature and possibly not calcareous.
Every day the plastic is removed to check the humidity of the soil and eliminates the condensation that will surely have formed from it.
Once the first shoots start to appear, it means that the cutting of Trachelospermumhas ingrained. At that point the plastic is removed and the pot is placed in a brighter area, and the cuttings are strengthened. In spring they will be ready to be planted.
PARASITES AND DISEASES
They are plants particularly resistant to parasitic attacks and diseases in general.
The name Trachelospermum comes from the Greek trakelós "Neck, trachea" e semen "Seed" to allude to the shape of the tube of the corolla where the stamens are inserted.Jasminoides instead it derives from the name of the plant Jasminum and from the Greek oides "Similar" due to the similarity of the flowers to those of jasmine.
