Roses

• An ever-popular bouquet or centerpiece flower, roses represent love, friendship, beauty, innocence and passion. A single rose paired with baby's breath remains a classic statement of love, while large bouquets of rosebuds accented with ostrich plumes serve as trendy arrangements for parties and weddings.
  
  Tailor your bouquets or arrangements to the occasion by changing the color of the flowers used. Red, white, purple and pink roses each have different meanings or symbolism, and, when combined, can send messages of everything from abiding love to desire and unity, according to Morrison Gardens.
  
  

Daisies

• Perhaps the most cheerful flower, daisies represent loyalty, beauty, patience and purity, according to Living Arts. April's birth flower, the daisy is a popular choice for informal weddings, bright picnics and barbecues, or simply to perk up a kitchen. Reinforce the stems with floral wire to hold blossoms up and prevent drooping or bent and broken stems.
  
  Arrange in clear glass vases with colorful rocks or filler at the bottom and tie ribbons patterned in gingham, stripes or plaid around the vases for a cheerful decor that coordinates with picnic blankets or party tablecloths. Use silver vases full of hot pink and orange Gerber daisies accented with sprays of pearls or bright crystals as centerpieces for a bold wedding reception.
  
  

Lilies

• From stargazer lilies to calla lily blooms, these flowers speak of elegance and gaiety. Lilies were revered by the Greek culture, according to Teleflora, are affiliated with the Virgin Mary and the second and 30th wedding anniversaries, and are the birth flower of the month of May.
  
  Arrange groups of lilies in similar colors, sizes or types for a uniform centerpiece, or mix different types of lilies for an explosion of color and style. Add sprays of pearls and jewels that mimic the shape and color of calla lilies and lilies of the valley, and use broad-leafed greenery to accentuate their shapes and graceful curves.
  
  

Tulips

• Teleflora states that tulips "represent elegance and grace," and are often likened to red roses for their symbolism of pure and perfect love. Associated with the eleventh wedding anniversary, tulips originated in both Persia and Turkey, and have achieved global notoriety for their variety of colors and styles. The simple curves and bright colors of tulips make them ideal for spring weddings, formal affairs and Easter decorations. Milk-white vases create a pure background against which the bold purples, yellows and pinks of tulips pop. Mix arrangements of cut and potted tulips for a less formal spring wedding to create an organic atmosphere.
