Petite earthy oases wend their way down the table, making for intriguing centerpieces. Succulents, lotus pods, air plants, and moss lay a foundation of green, purple, and gray shades. Lighter hellebore, fritillary, and lady-slipper orchids punctuate it. After your reception, pot the succulents in soil to decorate your newlyweds’ nest and remind you of your special day for years to come.
