Passion flower development: Answer: passion flower

Dear Lucia,
passiflores are climbing plants originating from South America, which have been imported into Europe and the world for centuries now; especially the Passiflora caerulea (the typical, classic, with blue and white flowers) is a weed, considered in most of the world a sort of scourge, as its development is very broad even in a single vegetative season, and its tendrils they can attach themselves to anything: other plants, tree trunks, trunks, branches, poles, railings. In fact, in Italy invasive development is reduced by the cold winter climate, but despite this it is usually avoided to approach it with other creepers, because over the years it tends to suffocate the other plants, sticking to their branches with tendrils. In your case, the plants with which you have planted the passion flower are quite vigorous, and therefore they should be able to coexist without major problems, even if it would be appropriate for you to periodically resize the passion flower, in order to leave room for the wisteria, the vine and to roses. However, consider that the three vines you have planted are all very vigorous, if you put them at a certain distance they should find ways to live together without major problems. If instead of the caerulea you have planted another variety of passionflower, then you should not have any major problems, because the other varieties cultivable in Italy are not so invasive. Certainly a regular pruning is advisable, in order to shorten the branches that tend to approach the other plants, which will also serve to flesh out the base of the stem of your passion flower. Consider that these plants root very easily, especially for offshoots and even without your help; therefore, every time the stem of your passionflower turns down and falls on the ground, over a few weeks it will tend to root and give rise to a "new" plant. So be careful, and when you prune the plant (in autumn or late winter) remember to also remove any new points where the plant has rooted, or else its root system will encircle the other plants on the gazebo, absorbing water and salts minerals also in the area where wisteria, grapes and roses develop. So, the passionflower will tend to develop trying to make room for other plants, but you can adjust its development, leaving more space for the plants around it, so as to balance the development of each single climber.
