Dawn, I just saw your question in the good morning post about the plant varities at the Farmer's Market.
FI and I were just looking for herbs when we were there, we can only garden in pots on our patio, so topiaries and bushes wouldn't do us much good.
We got thyme, peppermint and parsley (because we already had cilantro, chives, taragon, lemon thyme and oregano from somewhere else). We were looking for a globe basil, but the only basils we can find are other varities.
Beka can probably speak to the other plant varities more than I can.
