You can use any color of pumpkin. Or you could try gourds in different shapes.
I love doing a fresh pumpkin flower vase using the large pumpkins that are sold for front porches.
These big orange pumpkin flower vases are perfect for a dramatic and festive statement on your dining room table. Or in an entry way.
If you're weather is nice outside, consider putting a fresh pumpkin flower vase on your porch to welcome guests.
