Many feelings can be expressed by flowers, and this non-verbal language is very popular nowadays. Each one of us has sent at least one message to someone with the help of a flower. Sometimes whole conversations between two lovers are spoken through flowers.
The most meaningful flower of all is considered to be the red rose. A single red rose is now usually used to send a message of love. There are also many messages that can be sent through single roses, like :

• A single white rose is used by someone that wants to say 'I'm sorry' to his/her significant other. It also has some other meanings. Since medieval times, white roses are considered to be a symbol of light, purity and innocence. So sending a single white rose may also mean that you consider that person to be pure, or that your love is very pure.
   


• A single yellow rose expresses happiness and love. Sending a single yellow rose to your other half means that you are happy with your love and relationship. But be careful because single yellow roses have two meanings! They can also express jealousy, so sending someone one can mean that you are jealous. The best thing to do is to attach a note to the rose, explaining exactly what you mean.
   


• A single peach rose is used to send a message of friendship to a best friend or even to a lover.
   


• A single purple rose expresses beauty. So if you want to tell someone he/she is beautiful send him/her a single purple rose.
   


• A single pink rose is an elegant way of thanking someone because this is what pink roses transmit: gratitude.
   


• Finally, a single black rose says 'it is over'. This is a way of ending a relationship - sending a single black rose together with a note.
