I do the Medicinal herb garden at the Western Reserve Village gardens in Canfield, Ohio We have 8 or 9 different theme gardens. Culinary, Decorative, Childrens, Tea, Dyers,American Indian, Settlers, Shakesphere,Knot.
I have saved some seeds from last year. False Indigo, Chinele, Yarrow, Blue basil (having a hard time trying to get it to germinate, but plan to buy it again for this year) One small plant 3' dia and 2' tall BEAUTIFUL.Have a few others too. Haven't been out to see what made it through the winter.
We added a new section last year too include a larger varity of medicinal herbs. Have lots of books on the subject.
Got a new book Peterson Field Guide Eastern/Central Medicinal Plants and Herbs. Buy it on Amazon as a used book. About $7 plush shipping. Wonderful book.
I've done Medicinal herbs since 1995 in the gardens.
Your plants look great. I do some in pots at home too.
