The southern Rhône has only the river in common with the northern Rhône. The countryside here in the flatter, southern part of the valley is definitively southern, almost Provençal, with both houses and vegetation demonstrating the influence of a mediterranean climate. Many other fruits are grown here, and one of the chief hazards is the sometimes cold wind that can blow down the Rhône valley. Most vines are gobelet trained, although Syrah vines are usually trained on wires in a single guyot system. If drought persists, some irrigation is permitted.
