How long do preserved flowers last in a jar?

Preserved flowers are different from fresh ones. They have been dried and treated with a solution, often glycerin, so they stay supple and colourful. In a sealed or open jar, they can last from one to three years, and often longer if you look after them. Direct sunlight will fade their colour over time, and humidity can make them droop or grow mould. Keep the jar in a cool, dry spot, away from radiators and steamy rooms. You do not need to add water or mist them. Dust them gently with a soft brush or a hairdryer on a cool, low setting. If the jar has a lid, keep it closed to protect them from dust and moisture. If you want them to last even longer, choose flowers that dry well, such as roses, lavender, statice, or hydrangeas. Preserved flowers make a lovely keepsake from a bouquet, but they are not indestructible. Treat them as a delicate decoration, not an heirloom. If you plan to keep them for many years, consider having a small piece professionally framed instead.
