Are there any plants that can hydrate themselves from humidity?

Trees on the west Coast of the United States "harvest" fog as it rolls over the hills and mountains. Without it they wouldn't be able to hold onto enough water to grow so large in their native environments. The soil doesn't hold onto water due to steep slopes, so large conifers such as Redwoods evolved to absorb water from the fog.
