Culinary lavender can be purchased online or in stores. Some common brands you could find in grocery stores or purchase from their online shops would be Morton & Bassett or Spicely Organic Spices. You can also go to World Market, where they sell their own brand of culinary dried lavender. On Etsy, you’ll also find many brands selling culinary lavender. Be sure you look for the culinary-approved ones and read reviews. If you’re in a pinch, you can also use most lavender tea leaves.
