Today's plant is Lemon Grass, or Andropogon or Cymbopogon Citratus, depending on if your use is medicinal (Andropogon) or culinary (Cymbopogon).
It's great in Thai dishes and Indonesian plates. The maintenance manager at the Hoyt Cooperative states that this herb is growing in our garden for use in cooking, but I have not yet taken the time to spot it. I will search it out today and most likely include it in my meal if the plant is established. One must harvest it from the bulb, not leaf, so finding a plant that is healthy with multiple shoots is essential to continual harvest.
