I recently received a flyer from the Point Breeze Organization about the Mellon Park Herb Garden:
The Elizabethan Herb Garden beds include culinary and medicinal herbs, a fragrance garden, a dye garden, a knot garden, a tea herb garden, a Shakespeare garden, and a rose garden. The Pittsburgh 250 Garden celebrates the 250th birthday of the city of Pittsburgh, and includes vegetables, fruits, and herbs that were grown at Fort Pitt (now Point State Park) at that time. This summer, a section with edible herbs and herbs native to Africa has been added.
Wikipedia lists the Mellon Park Shakespeare Garden/Elizabethan Herb Garden as one of only 34 such gardens in the world!
This garden is definitely worth a visit if you have the chance. Mellon Park is right along 5th Avenue, and quite near the practice site. On Sundays, you can park right on 5th Avenue!
