In Vancouver, WA a bowl of roses or a potpourri bowl is an exhibit that uses many blooms in a bowl usually a rounded design. You would use as many roses as needed to make a nice even rounded arrangement. Some use all the same color roses others use different colors.
In Tacoma an HT in a bowl is one HT bloom floating in a bowl of water.
Are you looking at a show schedule? If so what exactly does it say?
I would have it would have been a HT floating in a bowl of water. But on the schedule it say's, Roses in a Bowl, so I'd say they mean more that 1 rose!!
