I have no idea what they are intended to do or what area in my life they are going to improve or affect. Does anyone know what white flowers, specifically in the bedroom are for?? Thanks in advance!

I'm not certain what the symbolism of white flowers is but I can assure you that simply having flowers in a room will not change your life - only you can change your life.

This is the list I know

Red Rose symbolizes love, passion, desire and respect.
Yellow Rose symbolizes friendship, caring, happiness and freedom.
Coral Rose symbolizes desire.
Peach Rose symbolizes modesty.
Dark Pink Rose symbolizes gratitude and appreciation.
Pale Pink Rose symbolizes grace, admiration and sympathetic thoughts.
Orange Rose symbolizes fascination and enthusiasm.
White Rose symbolizes innocence, reverence, humility and truth.
Purple/Lilac Rose symbolizes love at first sight, enchantment
Red & Yellow blended symbolizes gaiety and joviality.
White and Yellow combined symbolize harmony.
Red Roses and White combined symbolize bonding and harmony.

Feng Su deals with a lot of decorating for harmony and balance.

Sounds like it might be feng shui. Here's what I found concerning flowers in the bedroom:

"To bring romance and love to your bedroom (or to kick-start it if your romantic life is floundering), moving your furniture, adding a mirror and a vase of fresh flowers can help to bring back that lovin' feeling."

In everything I have ever read black flowers = death and white flowers = purity.

Nohelp, my answer was to whiteflowers, but if you must know every mothers day my grandmother would where a white rose in memory of her dead mother, and the women with living mothers would where a red rose .

I have never heard of that tradition.
Brides wear white and all other references I have ever heard white is purity.

In some asian cultures white is worn to funerals and red or black is warn to weddings.
