Preserved flowers stay soft, flexible and lifelike for months or even years — unlike dried flowers, which become papery and brittle. Achieved by replacing the moisture in a flower with a preserving solution, the technique keeps blooms looking almost fresh. This guide explains what preserved flowers are, how to preserve flowers at home with glycerin and other methods, and how the famous preserved “eternity roses” are made.
What are preserved flowers?
Preserved flowers are real flowers treated so they retain a fresh, supple appearance long after they would normally wilt. The most common method replaces the water and sap inside the flower with a glycerin-based solution, which keeps the petals soft and natural-looking. Preserved flowers differ from dried flowers, which simply have their moisture removed and become dry and papery, and from silk or artificial flowers, which aren’t real at all.
How to preserve flowers with glycerin
Glycerin preservation is the classic method for keeping flowers and foliage soft and lifelike. It works especially well for sturdy flowers and greenery like eucalyptus, ferns and roses.
- Mix one part vegetable glycerin with two parts warm water in a container.
- Trim the flower stems at an angle and lightly crush the bottom inch of woody stems so they absorb the solution.
- Stand the stems in the glycerin solution, about three to four inches deep.
- Leave in a cool, dark place for two to six days (foliage) or up to two to three weeks (flowers), until the petals feel supple and slightly changed in color.
- Remove, wipe the stems and let them dry — the flowers will stay soft and lifelike for a year or more.
Glycerin can also be applied to individual leaves and foliage by fully submerging them in the solution.
Other ways to preserve flowers
Resin
Casting flowers in clear epoxy resin preserves them permanently inside jewelry, coasters, paperweights and ornaments. Flowers are usually dried or pressed first, then set in resin for a crystal-clear, lasting keepsake.
Wax dipping
Dipping fresh flowers briefly in melted (not too hot) paraffin or soy wax coats and seals them, extending their life for a week or two with a fresh look — a lovely short-term way to preserve a special bloom.
Silica gel and air-drying
Technically drying rather than true preservation, silica gel and air-drying remove moisture to keep flowers for years, though the result is dry rather than soft. See our how to dry flowers guide for these methods.
Pressing
Pressing preserves flowers flat for framing and crafts. Learn the techniques in our how to press flowers guide.
Preserved roses and “eternity” roses
The luxurious preserved roses sold in gift boxes — often called eternity or forever roses — are real roses preserved with a glycerin-based solution and often dyed for vivid, lasting color. They can last one to three years with no water or sunlight needed, which is why they’ve become a popular romantic gift. You can approximate the effect at home using the glycerin method above, though commercial preservation uses specialized solutions for the longest-lasting results.
How long do preserved flowers last?
Preserved flowers typically last one to three years, far longer than fresh (days) and often looking better than dried flowers over time because they stay soft and colorful. Keep them out of direct sunlight and away from humidity and water, and dust them gently, to maximize their lifespan.
Preserved vs. dried vs. fresh flowers
Fresh flowers are the most vibrant but last only days to a couple of weeks. Dried flowers last years but become papery and muted. Preserved flowers bridge the two — they last years like dried flowers but keep a soft, fresh-looking appearance like fresh ones. The right choice depends on your budget, the look you want and how long you need the flowers to last.
Tips for preserving flowers
- Start with fresh, just-opened flowers in peak condition.
- Use vegetable glycerin, available at pharmacies and craft stores.
- Preserve sturdy flowers and foliage for the best glycerin results.
- Keep preserved flowers dry — never add water.
- Display out of direct sunlight to prevent fading.
How to preserve a wedding bouquet
A wedding bouquet is the ultimate keepsake to preserve. Act within a few days of the wedding while the flowers are fresh. You have several options: preserve the blooms with silica gel or professional freeze-drying to keep their three-dimensional shape, press the flowers flat for framing, or have the bouquet professionally preserved in resin. Many couples choose a specialist bouquet-preservation service, but silica-gel drying at home (see how to dry flowers) can beautifully preserve the key blooms to display under glass or in a shadow box.
Caring for preserved roses
Preserved or “eternity” roses need almost no maintenance, but a few rules keep them perfect: never water them (moisture ruins the preservation), keep them out of direct sunlight to prevent fading, avoid humid rooms, and dust gently with a soft brush or cool hairdryer. Keep them in their display box or a covered container if possible. Treated well, preserved roses stay beautiful for one to three years.
Preserved flowers in resin and jewelry
Setting preserved or pressed flowers in clear epoxy resin creates permanent keepsakes — pendants, rings, earrings, bookmarks, coasters and paperweights that capture a real flower forever. Flowers must be fully dried or preserved first, since any moisture clouds the resin or causes browning. Resin crafts are a popular way to turn a wedding, memorial or garden flower into wearable or displayable art.
How much do preserved flowers cost?
Preserved flowers cost more than fresh or dried because of the labor and materials involved. A boxed preserved rose arrangement or “eternity rose” typically ranges from moderate to luxury pricing depending on size and presentation, while professional bouquet preservation is a premium service. Preserving flowers yourself with glycerin is far cheaper, costing little more than a bottle of vegetable glycerin, though home results are less uniform than commercial preservation.
Preserved flowers FAQs
How do you preserve flowers at home?
The classic method is glycerin preservation: stand trimmed stems in a solution of one part glycerin to two parts warm water in a cool, dark place for several days to a few weeks until the petals feel supple. This keeps flowers soft and lifelike for a year or more.
What is the difference between dried and preserved flowers?
Dried flowers have their moisture removed and become papery and brittle, while preserved flowers are treated with glycerin or similar solutions so they stay soft, flexible and lifelike for years. Preserved flowers look fresher for longer.
How long do preserved flowers last?
Preserved flowers typically last one to three years. Keeping them out of direct sunlight, away from humidity, and never adding water helps them stay beautiful for as long as possible.
How are preserved roses made?
Preserved or “eternity” roses are real roses treated with a glycerin-based solution that replaces their natural moisture, keeping them soft and lifelike, often with added dye for vivid color. They can last one to three years with no water needed.
Can you preserve flowers in resin?
Yes. Flowers are usually dried or pressed first, then cast in clear epoxy resin to preserve them permanently inside jewelry, coasters, paperweights and ornaments for a crystal-clear, lasting keepsake.
What flowers preserve best with glycerin?
Sturdy flowers and foliage preserve best with glycerin, including roses, eucalyptus, ferns, hydrangea and magnolia leaves. Delicate, high-moisture blooms are better dried or pressed.
