Dear Aniello,

unfortunately you do not tell me in which region this pergola is located, so it is difficult for me to give you advice that is suitable for all of Italy; if you live in a region of central north, I recommend, instead of jasmine, a trachelospermum jasminoides, also called evergreen jasmine: this plant has flowers very similar to those of jasmine, with an identical scent, but much more resistant to frost, and moreover, the summer flowering is much longer. An excellent climber is also the honeysuckle, it has deciduous leaves, but the flowers are beautiful and very fragrant, or the pandorea, always with evergreen leaves, with beautiful summer flowers, in the shape of pink trumpets. If, on the other hand, you live in a region with a fairly mild winter climate, then you can try growing a real jasmine, jasminum officinale, which blooms in early spring, a very elegant plant, with evergreen leaves; or you can use a bougainvillea, with its spectacular purple flowers. For if you want to grow all the plants listed above, consider that they all need at least 4-5 hours a day of direct sunlight, or risk that they will not bloom in any way, or even be attacked by parasites of all kinds. To have a healthy and luxuriant climber, then consider that you will have to guarantee the right space for the root system, providing each plant with a large pot, such as a tub at least 60 cm wide, about 3 cm high (-40 cm and as deep as the your large pergola, it is advisable to think of two or three pots, and in each place a single climbing plant; then the pot can be filled in the surface area with small flowering plants, even annuals, such as geraniums or surfinias for example. pots have nice drainage holes, because these plants do not like water stagnation, and since you are on a terrace, also think about saucers, or you risk letting a lot of water run every time you water. be the best possible, very rich and well drained, possibly mixed with pumice stone or lapillus, to prevent it from retaining excessively water, especially during the winter months. At the end of winter, every year, check that the soil in the pots has not dropped to depth, then remove a good amount of it, add fresh soil and slow release granular fertilizer.
