Did you ever wonder why red roses are used for Valentine's Day or Carnations for Mother's Day? Well, it's because flowers have historical meanings. The language of flowers - what they mean - has endured for centuries. Here are a the meanings of some familiar favorites.

Roses - Roses are one of the most popular flowers, and for good reason. They are beautiful, smell great, and come in a wide range of colors. In general, a rose symbolizes love. However, each color or rose has its own meaning. Red roses mean passionate, romantic love. White roses represent an innocent, pure love and new beginnings, which is why they're so traditionally popular in weddings. Choose yellow roses and you're expressing friendship. A dark pink rose is a great way to say thank you.

Sunflowers - It's not hard to guess the primary meaning of sunflowers. Their bright, bold color simply radiates joy. If you want to lift someone's spirits, or let them know how much happiness they bring you, an arrangement of sunflowers is a good choice. Because of the sunflower's ability to provide nourishment through seeds, it's often associated with health and longevity as well. This makes sunflowers a good choice for a get-well bouquet.

Daisies - Daises come in so many colors and varieties, that it's easy to see why they are a favorite of florists. They can be used for multiple occasions where you want to send a simple message of affection or congratulation. Birthdays, promotions, a thank you gift, or bridal showers are ideal occasions for daises of any color combination. Historically they represent innocence and beauty, so these flowers are a good choice when you want to send a gift to a child.

Tulips - Tulip meanings can be somewhat complicated. They've been around since well before the 16th century. Thus the meanings of each variety and color have evolved over time. In the past, the tulip was a symbol of a perfect love, or of being deserving of love. In modern times, the tulip generally indicates forgiveness - forgiving someone or asking to be forgiven. They are also often used as part of an overall romantic arrangement in combination with roses.

Carnations - As symbol of gratitude, it's no wonder carnations are a symbol of Mother's Day. While pink is more about being grateful, white also can bring wishes of luck to the recipient. Red carnations can convey admiration, but if you're giving flowers to your mother or sister, avoid the deeper red color, which has a romantic implication.

Irises - This flower has a long history as well. A favorite of Egyptian and Greek royalty, it was historically a flower of grand occasions. Today, it is considered a flower indication deep and lasting friendship. Yellow irises can symbolize passion, but more of a passion for something rather than a romantic passion. If someone you care about got a promotion, achieved a special goal, or who you want to send a bit of encouragement, choose a bouquet of irises.

Now that you know the language of flowers - what they mean and which colors to choose, you can tell those close to you how you really feel. Your florist will also be able to help you choose the appropriate colors and floral design to complement your message. Send along a personalized note with your sentiments, and you'll have the perfect gift!
