Lancôme is working with IFF and Leclef to develop rose plants that require less water, but that's several years away, says Lehmann. In the meantime, the property has two basins that collect water from the hills above and the river below; it uses no water from the town system. Leclef's team has devised a schedule in which they give the roses more water less often, to get hydration deeper into the roots — and ultimately use less water. The main building on the property, used to host visitors and educational sessions, is insulated with the lavender straw that grows a few meters away and doesn't have air-conditioning.
