Delicate and desirous of as much moisture as possible, the orchid -- fragile, yet awe-inspiring in its beauty -- would be the appropriate flower to appear at a Pisces wedding. Like the acrobatic twin Fishes, the orchid displays the ultimate in flexibility. Its stems contain no fiber, and the plants are adaptable enough to grow from one stem or a series of adjacent shoots. It's hard to dispute, also, that orchids have an unearthly beauty that parallels Pisces' ethereal power of attraction and the appearance of having just been plucked from a dream world.
