I am a student member of the Illinois Herb Association. 

IHA has a project where they would like an

Official Certified Herb of the Year Garden in each county.

I used a raised bed  for my herb garden, it has 34 of the Herbs of the Year planted in it, using a 4 X 8 three tier raised bed garden, with a trellis.  It has been Certified by the IHA, as an Official Certified Herb of the Year Garden for Jefferson County in Illinois.
