Most plants do NOT take up water through their leaves. Some liquids,
however, contain chemicals that penetrate the barrier against water.
These liquids include herbicides and urine.

The needles of coast redwoods (Sequoia sempervirens) trap moisture from
fog. They have tiny rootlets, not on the needles but on the branches
adjacent to the needles, which then absorb the water. In areas where
there is little fog, coast redwoods that have been planted as part of a
landscape must then be hosed down, top to bottom at least weekly.
