Question
I want to make an arrangement in a large 25 inch floor vase but am not sure what type of flower and what shape to give the arrangement. The vase is made of metal, is oval at the top, a smaller neck and flares rounded at the bottom.  It has the colors of dark brown, gray, and shows grape leaves and bunches of grapes at the bottom.
Colors of cream, and shades of purple would be appropriate.
I'm an amateur arranger, so any advice will be appreciated.  Thank you.

Answer
I would go with flowers that you might find in a garden to give it a wild, airy look.  Curly willow should certainly be used, in my opinion, and perhaps some grape vine, too.  You'll want to use some tall flowers that grow on stocks.  For flowers, I'd go with things like crab apple blossoms and larkspur for height.  I think hydrangeas would be a nice touch to fill around the bottom.  Maybe use alstroemeria throughout the arrangement, as well.  Don't forget the importance of greenery.  I think some ivy trailing from the mouth of the vase would look nice.
