WOW sgtiger! WOW! I love it! I've wanted to do something like that myself, integrating ornamentals with produce in my front yard since it gets more sun than my backyard, but DH pooh-poohs me (and we're moving at some point anyway, might as well keep the easy-care perennials out front). Maybe if I show him your incredible pics he'll be ok with it for our next house. :-)
Grey, we've been gradually replacing ornamentals with vegetables. As my DH says, it takes just as much work to look after the ornamentals as the vegetables so why not have the fresh veggies. Last fall we added two raised beds to our front yard and planted carrots, beets, onions, swiss chard, peas, and random dill in the beds. That's my DH picking swiss chard in the rain!
So far, the neighbours have been intrigued more than anything else by the gardens in the front yard. My goal eventually is to replace all of the lawn with a mix of vegetables & ornamentals - but one year at a time!
