Two Tier Spiral Tower in Ceramic VaseThe two tier tower has for centuries been the standard design for lucky bamboo. Its simple lines have been unchanged ..... until now! With the success of the Lucky Bamboo shop's Three Tier Spiral Tower and many Requests, we have persuaded our designer that a smaller version was needed.To the center of the layers of 4" and 6" stalks, a selected 8" spiral lucky bamboo was added. This gives the arrangement height and added interest as the spiral takes on different looks as viewed from each perspective. The Two Tier Spiral Tower Arrangement is above 15" tall and the style of the 5 1/2" dia. Ceramic Vase.
