An idea relevant to my wife's "knick-knack" shelves. The glass Boutonniere vase is three inches tall and designed for larger buds. The two Japanese Cloisonné vases are metal and hollow (for burning incense originally) but could be converted to carry a flower stem. I would think that like the "nosegay" lapel holder, no water would be necessary. There are rings attached to the ears of the vases also, so mounting with a pin would be no problem.
