Where can I buy dried flowers?

Check aliexpress.com

If you have time you could dry them yourself if you have the space to hang them. There are a ton of youtube videos with tips on drying flowers. Good luck!

Hey Arlene! Great advice from the previous posters! Amazon would be a good place to check! Were you able to find some at a great price since?

Artificial flowers on amazon site in bulk/lot are a great deal to save with what you can get for the quantity. Lavender is available upon styles shown.

Other websites will also carry them, though not sure on the pricing and quantity based. Comparing ranges and styles would be a good idea to know which deal is the best to get.

My first suggestion was going to be Etsy but I see you've tried there. Amazon.ca has some, particularly lavender. And then you can get free shipping if you or someone you know has Prime membership.

Another option may be to get it from a florist but unarranged. Look for a florist who focuses on locally grown, sustainable flowers because they will frequently dry flowers in-season to use out of season. This type of florist is becoming more common and sometimes refer to themselves as an "urban flower farm". I know my florist dries flowers to use out of season.
