Looking up plant names today I read that some are named after mythical Greeks. So far I have found those below. Do you know any others?
Chloris – Goddess of flowers
Daphne – Goddess of laurels
Hebe – Goddess of youth
Helia – Goddess of the sun
Iris – Goddess of the rainbow
Leucothoe – ex love of Apollo
Narcissus – the youth who loved his reflection
Tithonia – named for a man loved by Aurora
Mark,
Since I've always been very interested in the Greek world of the gods, a few elaborations
Iris was also the messenger of the gods (later Hermes took on that role)
Narcissus fell in love with his own reflection because he was punished for ignoring a nymph (named Echo (she withered away after he had refused her love and only her voice remained)) who had fallen in love with him
The man Aurora loved was Tithonos
Boopis was an epithet used for a few gods and godesses (means cow-eyed)
Cassiope: Greek queen, mother of Andromeda
Andromeda: wife of Perseus
Dionysus: God of wine and ecstasy (not the drug

) (original god of vegetation and agriculture)
Artemisia: (Artemis): Goddess of the hunt, forests and wild animals
Polemus: personification of war (almost the same as Ares)
Adonis: Love of Aphrodite (and Persephone)
Achillea: (Achilles): Hero of the Trojan war, killed by Paris
Paeonia (Paeon): physician of the gods
Hyacinthus: lover of Apollo and Zephyrus, killed by a discuss thrown by Apollo
Centaurea: named for the centaurs
Asclepias: God of medicine and healing
Hypericum: (Hyperion) Titan, ruler of the light
