Wave after wave of scent has filled the air since my garden awakened in spring.
Most prominent have been the aromas from daffodil blossoms, plum, flowering currant, and now dame's rocket, pinks and roses.
Of course, it's not for us that flowers waft those sometimes delectable aromas.
Evolutionarily speaking, we don't return the favor with anything more than the carbon dioxide that we and all other animals breathe out, and that plants use for photosynthesis.
Flowers release their aromas to attract pollinators.
