The freeze dried rose petals are our premium confetti petal. The freeze dried rose petals are purpose grown on a farm in the Netherlands. The petals are handpicked to prevent damage to the petals. After the petals are harvested, the freeze-drying process begins. The process of freeze-drying produces fantastic results with petals that don't shrink, they retain their shape, they don't discolour & retain their stunning natural colours. They almost appear like fresh petals.
