Quick french bean question

My French beans HAVE to be planted today because the roots are poking out of the sides and bottom of their newspaper pots, and they are so big that they are starting to set flowers 

My question is - do I place the plants in FRONT of the canes or BEHIND or doesn't it matter? Is there any advantage in planting position?

Good idea - the clumsy plates of meat in question are likely to be our two bearded collies!!! They don't usually trample on to flower beds, but one should never take the chance, especially if a badly aimed ball is thrown in that direction! Many thanks.

If we're talking the non-climbing French bean, I find canes totally unnecessary if you plant like this:


*   *   *   *   *   *   *   *   *   *
*   *   *   *   *   *   *   *   *   *


*   *   *   *   *   *   *   *   *   *

Double rows, 9" between each plant (star), 18" between the double rows. They've always been self-supporting.
