You'll probably do best with herbs. You can lay them out in a formal,
European style garden plan and then when the snooty neighbors ask what
this or that plant is, you can pluck a leaf or stem and eat it right in
front of them. I imagine it could be fun to watch their reactions. :-)

Seriously, in addition to all the other good suggestions, including
terraces or big containers in the back yard, letting some garlic and
onions go to flower can add a nice touch as well. There are even some
strictly ornamental onions that are bred just for this purpose.

What would you recommend to grow in front yard, so it is edible and
looks good enough not to **** homeowner asscociation?
