PARTICULARITY

The botanical name comes from Greek and refers to the fact that the seeds (spermum) are in the “throat” (trachelos) of the flowers.

We can distinguish false jasmine from real jasmine (Jasminum officinalis) by some important differences. The Rhyncosperm is evergreen, it has a leatherier, darker leaf (except for the young leaves which are light), shiny and thick than the light, light green and opaque one of the jasmine.

The petals of the flower are inserted on the corolla rotated clockwise. Flowering is shorter and the scent is more decisive and sweetish than delicate with harsh notes of jasmine.

It is more resistant and luxuriant even in non-comfortable situations. Both cannot climb on their own, but the ricospermo has a thicker and heavier foliage which is therefore useful for shading arbours and gazebos all year round.

Finally, as we have already said in the properties, Rincospermo is toxic, while with jasmine you can also make sweets and infusions.

Rhyncospermum jasminoides: Annotations

Plant resistant to smog and pollution.

It is usually grown in the garden, to cover railings separating gardens, for pergolas, flower walls and hedges. However, if grown on terraces, pots of at least 40 cm (bottom) must be used as it has a large root system.

It is not afraid of frost and salt, so it can also be planted near the sea.
