Formal herb garden
I want to plant perennial herbs in one "official" newly created garden surrounded by retaining walls made of stones:
and possibly laurel bay (but sounds like it gets huge, so probably not...).
Could someone explain how much space each herb needs for planting (not from seeds)? I have been reading this forum, but still having a hard time coming up with one plan to do the planting of all these perennials, and hopefully allow each enough room to grow.
