Krishna is often depicted as romancing gopis (female cowherds), but consider……….Krishna and gopa boyfriends.
(In all seriousness, however, Krishna–since he is an incarnation of Vishnu–is canonically pansexual and often genderfluid.)
Edit: The name of the plant is the Parijatha, otherwise known as “Night Flowering Jasmine” in English. It’s Krishna’s favorite flower!
