It is also known as Blue Jasmine, but it is a shrub with long flexible branches and dense vegetation. Its branches reach 3 meters and you may need to support them. In the summer the whole plant is covered by its numerous flowers with an impressive blue color.
It grows quickly and is ideal for climbing fences, decorating walls or hanging from dry rocks. It can also be grown in large pots and jars on the balcony. It grows in both sunny and semi-shady places and has a fast and impressive growth. But you have to protect it from the cold.
It adapts to all soils and is good to be fertilized here and there to keep dark green foliage. It is also ideal for seaside plantings.
