Plumeria
Family: Apocynaceae
In the Philippines, these flowers are associated with ghosts and cemeteries; its shrub is also mildly poisonous!
Heliconia chartacea
Family: Heliconiaceae
The general family of this plant apparently represents youth, pride, and great returns. This one is also called 'Sexy Pink' but I'm scared of the search results it might yield, LOL
Desert rose
Family: Apocynaceae
A slow growing plant often used as a bonsai plant, though this one isn't. It's also poisonous but it could also be the whole family? Can you tell I'm not the greatest at this? Okay, uh-
