Marketing differs from selling because (in the words of Harvard Business School's retired professor of marketing Theodore C.

Samphire. Sometimes called sea asparagus, samphire is a remarkably rugged vegetable that you may have witnessed during a weekend trip to the coast. It grows in places few vegetables can: rocky, salt-sprayed regions near the ocean.
I also learned that this is a vegetable of a thousand names: sea beans, sea asparagus, samphire, glasswort, chicken feet, etc, etc. Probably its best name is salicornia, as all the various species of this salt-lover are in the genus Salicornia.
