Two possibilities:
One, a superhydrophobic surface reduces the surface area of the water that lands on the plant, allowing less of it to evaporate and more of it to fall to the ground.
Two, it may help prevent plant diseases by allowing less water to attach to surfaces that are prone to becoming diseased.
- tempestn 12y agoThat was my first thought. It's not a good idea to water your plants at night, because without the sunlight and heat of the day the water doesn't evaporate as quickly. Water sitting on the leaves all night can cause fungus and such things to grow, which is bad for the plant. Since plants can't avoid being rained on at night, it seems logical that they would evolve a mechanism for staying as dry as possible.
