What are preserved roses?

Preserved rose arrangements are growing in popularity and shaping up to be the biggest floral trend this year. They are a great alternative to fresh roses as they have a longer life span, are appealing and make fantastic gifts for any occasion. But you may be asking yourself what are preserved roses and how do they last so long? 
Unlike fresh roses which only last a few days, preserved roses are an economical alternative for decorating your home or gifting to a loved one. Preserved roses are real roses that have undergone a preservation process to maintain their beauty and freshness without any need for water or sunlight, allowing you to enjoy their beauty for up to three years if cared for correctly. 
How do they last so long?
The roses are carefully selected and harvested when they are in full bloom ensuring their beauty and quality is locked in time. The preservation process then immediately begins - a mixture of glycerine and other plant components gradually replaces the sap and water content within the rose, effectively forming a still image of nature. 
After the preservation process is complete the rose is pollen-free, making them safe for people who suffer from pollen allergies.
