Frequently Asked Questions About Preservation


What is freeze-drying?
Freeze-drying (lyophilization) is accomplished by sublimation of ice in a vacuum. The basic elements of this process have been known for over 70 years. However, it was not until World War II that much emphasis was placed on the refinement process. During this time, much attention was given to the development of equipment and techniques for the purpose of supplying large quantities of dried blood plasma and penicillin to the armed forces. By the end of the war, freeze-drying had become known as a near-perfect method of preservation.

Why is freeze-drying the best method of preservation?
The basic principle of freeze-drying is the removal of water from a flower as water vapor by means of a vacuum, and collection of this water into a condenser. With the flower solidly frozen during the process, shrinkage is eliminated or minimized.

What kind of equipment is required to freeze-dry?

Freeze-drying requires the use of a special machine called a freeze dryer. The freeze dryer has a large chamber for freezing and a vacuum pump for removing moisture.

How long do freeze dried flowers last?
Since the freeze-drying of botanicals began in 1989, it is still too early to say that freeze-dried flowers will last forever. However, when protected from humidity, sunlight and insects, freeze-dried flowers can last for many years.

Why should I have my flowers preserved?

Once flowers are used in a ceremony or given by a special person, they become sentimental. Let us make those memories last by creating a floral keepsake. When you spend hundreds of dollars on flowers for one day, doesn't it make sense to preserve them for years?

How long does the process take?
After your flowers are received, rehydrated and pretreated they go into the holding freezer until the freeze-drying machine is ready to load. Once in the machine, the process will take 14-21 days.

How long do I have to get my flowers to you?

We prefer to receive flowers within 24 hours after the event. However, certain flowers can be kept refrigerated several days.
