If you screwed up, flowers are a great way to say I’m Sorry. That’s why some flowers are "I am sorry flowers". But flowers can do more. I’m Sorry is just a small part of the language of flowers. Buy your significant other roses and you are off the hook. Be careful though. Buy her the wrong roses and you are deeper in trouble then ever before. Buy 25 roses and what you are saying is “Thank You”. It should have been 1 rose if your message is “I Love You” or 50 roses to express “Unconditional Love”. Color? Important! Red is love (obvious), Yellow is jealousy (even if it’s her favorite color) and black foreshadow of death.
