I understand the concern expressed about the possible harm that can come from eating some plants, or the fruits (deadly nightshade for example) or the seeds (laburnum springs to mind since the pods look, to a child, just like peas).
However, planting only edible things in the garden may sound alike a good idea - but all that teaches the child is that all those lovely, ripe red berries - raspberries, strawberries etc are nice to eat. What it doesn't do is teach them to differentiate between the edible, the unpleasant and the toxic. After all, when they visit a friend's garden, the parenting and planting may be somewhat different.
I taught my son only to eat what he knew was OK - ie what he had been taught was safe, and never to eat anything else before checking. Like others' advice, I reckon this philosophy would serve anyone well
