I made it myself. I dried rose petals and herbs, added in stick cinnamon, whole cloves, and added a few drops of 3 or 4 essential oils that I have on hand, together with a tiny bit of coarsely ground salt.
Recently at my local Dollar Tree in Thomasville, NC, I found a product called Herb Rocket. It is herb seeds in a rollup mat. The directions indicate that you just plant them and water them. Several different herbs were available; I chose Italian parsley, because I use a lot of it in cooking. Just planted it in my patio area. Will see how it goes.
