I realize this is an old post, but I had to chime in and say Yes, please! Both lavender and rose petals (and rose hips, for that matter) would be *very* welcome additions!
It would be lovely to see more single-ingredient options in the herbal section in general; lemon balm, fennel, holy basil/tulsi, dandelion root, ooh, and stevia! It would be *awesome* to be able to add actual bits of stevia to blends!
Anyhoo, thanks for listening!
