A few plant names with Greek roots have mythological tie-ins, such as hyacinth and narcissus. Cypress plays that game too — it's from Cyparissus, a mortal boy, teen, or man depending on the version of the story. Cyparissus had a pet deer, whom he adored more than anything else in the world. One day, while in the forest, Cyparissus accidentally discharged his bow, mortally wounding his pet. Consumed with grief, remorse, and guilt, he threw his body over the suffering companion as the pet died, transforming into what we now call the Cypress tree. This is why many cultures around the world still regard a Cypress tree as a symbol of mourning and still use them in cemeteries or burial places.
