Last year, I planted Oregano in my herb bed. Before the winter, it was growing upright and had reached just under a foot tall. After the few freezes we had, it died back, but re-sprouted in early spring. However, now its growing like a ground cover instead of upright! It just keeps spreading and spreading. all three plants are doing the same thing in different parts of the bed... is this normal?
I have mine planted at fence edge and am diligent to only allow it 6" on either side of the fence - everything else is dug out in early spring when it emerges. Seems to work, although you also must be on alert for errant babies popping up outside the perimeter. Lovely plant for the bees.
