Why Preserve Flowers
Flower preservation includes six main methods: air drying (free, 1-3 year lifespan), pressing (cheap, decades lifespan in sealed frames), silica gel (moderate cost, 2-5 years, lifelike shape), glycerin substitution (moderate cost, 1-3 years, soft fresh feel), freeze-drying ($200-700 professional, 5-10+ years, most lifelike), and resin embedding (permanent keepsake). DIY suits sentimental personal use; professional freeze-drying suits wedding bouquets.
It is also a hobby and craft - flower pressing, resin jewelry, dried flower art. The methods overlap with sentimental preservation but the goals are different.
The Six Main Preservation Methods
Each method produces a different result:
- Air drying - hang upside down for 2-3 weeks; rustic look, papery texture; free at home
- Pressing - flatten between books for 2-4 weeks; flat 2D result; great for frames and resin
- Silica gel - bury in desiccant for 2-7 days; preserves colour and 3D shape exceptionally well; $15-30 DIY
- Glycerin substitution - replace plant sap with glycerin over 1-3 weeks; keeps soft fresh-looking texture; $20-50 DIY
- Freeze-drying - professional process; preserves full lifelike shape and colour; $200-700 commercial
- Resin embedding - encase pressed or silica-dried flowers in clear resin; permanent keepsake; $30-150 DIY
When to DIY vs Hire Professional
The decision depends on the bouquet and the result you want:
- DIY suits - sentimental personal bouquets, low-budget keepsakes, casual home displays, anniversary roses, single significant flowers
- Professional suits - wedding bouquets (especially full bridal bouquets), high-value sentimental flowers, archival-quality keepsakes
Wedding bouquet preservation is the most common professional preservation service in Canada. Pricing ranges $200-500 for a full bridal bouquet professionally freeze-dried and displayed in a shadow box or under a glass dome.
Method Comparison
The trade-offs by method:
- Air drying - cheap, easy, papery; vase or hanging display; 1-3 years
- Pressing - cheap, flat result; framed art or journal; decades if sealed
- Silica - moderate cost, lifelike shape; dome or shadow box; 2-5 years
- Glycerin - moderate cost, soft feel; vase display; 1-3 years
- Freeze-drying - expensive, full shape and colour; usually professionally done; 5-10+ years
- Resin - moderate cost (DIY) or expensive (professional); permanent; jewelry, paperweights
Best Method by Flower Type
Some flowers preserve better with specific methods:
- Roses - air dry (classic), silica (lifelike), or freeze-dry (best for weddings)
- Peonies - silica gel (the only DIY method that works); freeze-dry professionally
- Tulips - difficult; freeze-dry professionally or skip preservation
- Daisies, cosmos, pansies - pressing (their thin petals suit this method)
- Hydrangeas - air dry beautifully; the dried heads hold for years
- Lavender, statice, strawflower - air dry (they look almost identical to fresh once dried)
- Sunflowers - air dry the small ones; freeze-dry the large ones professionally
- Sweet pea, lily of the valley - pressing; too delicate for most other methods
Display Ideas for Preserved Flowers
How to show preserved flowers once they are done:
- Glass dome on a wooden base - for a single special bloom
- Shadow box frame - for wedding bouquets or pressed-flower art
- Hand-tied dried bouquet in a vase - for air-dried roses or wildflowers
- Resin paperweight or coaster - permanent keepsake from pressed petals
- Framed art (pressed flowers) - traditional and elegant
- Wreath - for dried flowers and grasses
- Sealed glass jar - for loose dried petals or potpourri
