​Gifting plants can mean many things, but most of all it means wishing good luck and telling someone that you care. Gift green friends to your friends to express your emotions.  An example of this is the Lucky Bamboo:  A gift of lucky bamboo symbolizes the wish for a strong life filled with prosperity. If you are giving lucky bamboo as a gift, the number of stalks given determines the type of blessing being bestowed. Two stalks are sent as an expression of love and are also said to double your luck.
