Different flowers are suited for different vases. Lilies look best when they lean; roses display better when they splay; wild flowers need shorter vessels; sunflowers should stand tall. You could buy a vase for every variety or just try Surface. Designer Achim Haigis took all of these factors into consideration and designed a porcelain piece that adapts. Instead of having one flat surface to act as a base, it has a series of peaks and plateaus so you can chose the angle it rests at. Play around with the look that best accents your blooms.
