Pumpkins and Winter Squash

• Remove the top of a small to medium size pumpkin or winter squash, the same way you would to make a jack-o-lantern for Halloween. Remove the seeds. Add a piece of florists' foam, cut to fit, in the cavity. Arrange flowers in complementary or contrasting colors by pushing their stems into the florists' foam.
  
  

Peppers and Eggplant

• Cut off the tops of large, squarish or block-shaped green, yellow, orange, purple or red bell peppers, the same way you would if making stuffed, baked peppers. Choose peppers that have a relatively flat bottom, so they stand up. Add a couple of inches of water to the insides of the peppers. Cut large handfuls of short-stemmed flowers of the same type and variety and put them in the peppers.
  
  

Tomatoes

• Choose a selection of tomatoes in different colors, sizes and shapes. Cut them from the plants with stems and leaves still attached. Arrange them on a pretty glass or silver platter as the centerpiece. A variation is to use all of the same variety of tomato, preferably a large, deep red-colored variety. Add tomato red candles in candle holders that coordinate with the platter on which the tomatoes are arranged for a simple yet elegant centerpiece.
  
  

Ornamental Cabbage

• Developing their colors after exposure to light frosts in autumn, ornamental cabbages are oftentimes used in floral arrangements as another flower, albeit a large one. The scalloped or pinked edges of their leaves and the creams, pinks and shades of green they exhibit after kissed by frost add a softer color palette than the usual crimson, rust, burgundy, gold and brown of autumn.
