This is not much more substantial than a sprig of parsley, and some of Walsh's earlier, indoor projects--planting ""kitchen scraps"" for crops of vines or blossoms--seem a bit pointless. Too, we wonder why the outdoor salad garden must be planted in plastic-lined baskets. (If it's for a city roof or terrace, she doesn't say so.) However, there is some variety to the suggestions she does offer--terrariums, cacti in colored sand, backyard vegetable and herb gardens; they come with enough hints (including using the county ag department services) to raise hopes for a harvest; and the spaced-out format and springy drawings make it all look like fun. Call it a side dish.
