Georgetown Pottery markets Ikebana vases for indoor flowers. Ikebana is the Japanese art of flower arranging. Georgetown Pottery designed the porcelain ikebana vases to be simple, graceful, and elegant. Not only do the flowers look great in all of the different ikebana vases, but they also help to extend the life of the arrangements. Each ikebana vase has a pin frog attatched to the bottom. The pin frog pierces the stem of the flowers and allows water to be absorbed by the flowers much longer than in any traditional vase.
