I love my lavender! Each year, I plant another because I can never have too much. I dry it, and it lasts for a year around the house. I’ve got French lavender and English lavender. I put it by my bedside table, I cook with it, I make sachets, and use the seeds to make simple syrup.
Here are a few DIY links form around the web, you can try with your lavender. Lavender bread, this looks so good, though I haven’t tried it yet. Lavender simple syrup, you can use this in summer cocktails (one of my fav’s is a lavender mojito). Lavender sachets, put them in your delicates drawer.
