Why stick to a square growing shape? or why not grow in a healing shape, that is also magical and also interactive. I found that Labyrinth is a wonderful way of planting flowers or herbs. I planned two magical Labyrinths in the site. The first one was a Labyrinth based on the magnetic shape of resonate around the earth and also based on the distance bee dance.
The second one was a thyme herb labyrinth based on a 5 circle cretan labyrinth shape. The thyme is planted on the dark path and the Woodchip area is the path to walk on. Hopefully the thyme will spread over time and will create a thyme hedge. So when walking the labyrinth not only the participants will benefit from walking the labyrinth shape but also they will be energised from the scent of the thyme!
