This is not my vegie garden - it belongs to Martha Stewart, literally down the road from my office.
A day ago I attended a cocktail party at the New York Botanical Garden celebrating Martha Stewart and her Edible Garden there. As usual, it was a gracious event, much as all Martha's endeavors are.

I walked through her Culinary Herb Garden, a display of the finest culinary herbs personally selected by Martha. The three tuteurs (I call them metal obelisks but what do I know?) in the garden were the lovely feature of the herb beds.....

Whatever the answer to that question I would like to share my circular 'edible garden' with you ...or what I call a great design for a vegie garden....
It derives from my opinion that edible plants prefer to grow in circle (biodynamic principles appeal to me). It also makes it more manageable and easy to maintain - and I am a veteran of the straight row vegie gardens - I know what I am talking about here. Circles win every time.

So won't you follow me into a circular edible garden? I made this video yesterday - please ignore the overhead airplane noise..
