Bouquet interpretation: hot and cold
The fancy florist that I walk past on my way to my favourite cafe has started putting some comparatively affordable bouquets out the front. Here's what you get for $20:
Iris: I have a message for you
Yellow roses: decrease of love, jealousy
Delphinium: fickleness, haughtiness
This bouquet is either saying "I've got a message for you: your haughtiness is making me love you less," or it's saying "I have a message for you, your fickleness is making me jealous." Both of which are pretty coherent as bouquet messages go, but probably not what you would have in mind if you decided to splash out for some nice flowers on a whim as you were walking past the florist.
Still, if you're looking for a bouquet for your manager who can't make up their mind about anything, or for your smug coworker who thinks they are better than you, this would be a great thing to pick up on your lunch break.
I'm sure that will help.
