Many like the look of an Garden theme.
The syle centerpiece that goes with that best is the topiary.

Perhaps you also want candles? This design fits all your criteria.

All you need to do is wrap our kit with Moss Cloth
(sold separately below) to acheive this very special look.

Votive cups/candles, flowers and greenery are not included.
Fill your bowl at the bottom with pebbles or rocks for weight.
