Some examples of flowers that work best for drying include:

• Sturdy blossoms: Small and sturdy blossoms like hydrangeas, amaranth, lavender, baby’s breath, celosia, and strawflower do well with air-drying because they have a lesser water content than other flowers and hold up well during the long drying process.
• Flowers with multiple layers: Large, dense flowers or flowers with open-faced petals like roses, tulips, zinnias, and chrysanthemums can withstand the heat of the oven or microwave.
• Smaller or flatter flowers: Small or flat types of flowers with a single layer of petals are the best ones to press. Some flowers that can be pressed include daisies, pansies, lavender sprigs, and violas.
• Larger flowers: Big blooms or more delicate flowers should be kept in a sealed container of moisture-removing substance. Lilacs, pansies, dahlias, peonies, and daisies hold up well when dried in a desiccant.
