I took a walk in my neighborhood a couple of months ago to find a nature preserve that ended up being closed for the day, but I did end up finding a really cool herb garden on the hill across the street. It was a lovely circular garden with benches, picnic areas, and some star observatory platforms. The herbs were lush and aromatic, including bergamont, mint, and bush sage among many others. I haven't been back since, but look forward to visiting again in the spring.
