If bonsai is something that interests you there are a wide variety of herbs that lend themselves to this art. Many familiar herbs are actually small shrubs such as rosemary, bay, sage, and lavender. Others tend to ramble around a bit but on close examination we can clearly see that they too have woody stems. What comes to mind includes thyme, savory, oregano, marjoram, germander, and hyssop.
If you want to create a beautiful display of herbs consider acquiring a good book on bonsai and try your hand at it. Richard W. Bender wrote a terrific book called Herbal Bonsai that specifically addresses using herbs as bonsai subjects. He explores many additional choices and provides step-by-step instructions on how to create beautiful, herbal bonsai specimens. I think this is a terrific idea to include in an indoor display mixed in with lush pots of green and purple basil, chives, ferny dill, and parsley.
