For a beach wedding I can imagine shells scattered on the tables, arrangements consisting of succulents, seaholly, orchids and lots of greenery. Maybe not a bouquet but flowers in the Bride's hair or a wrist corsage. One long table that everyone eats at or canape's flowing all night. Dancing under the stars.
Unstructured flowers everywhere as if they'd just been picked from the garden. peonie's, lissianthus, david Austins, freesia's, silver suede, magnolia, tuberose to name a few. There would be jars scattered along the centre of each table. Large arrangements and a wreath as you first walk into the marquee oozing with soft pink peonies, david austins, garden roses and silver suede hanging with string. Lanterns hanging from the trees.
I would be using what's on the land for instance natives. Lots of green red and mustard Kangaroo paw, green leucadendrons, seaholly, brazillia. The tables would be covered with hessian and antique cutlery would be used. To dress the table's candles, wine and green water glasses would be added which would give a fresh look and feel.
Crisp white tablecloths would cover the tables with the finest cutlery and dinnerware. Wine and water glasses on the table with one tall arrangement of structured roses on each. For lighting Chandeliers would be used. In a dominant section of the venue a sweet table would be set up with bite sized desserts in classic glass jars and cake stands. The colour scheme would be black and white with a touch of soft green.
