Ok this grouping requires a little more change but I'm just 'can kicking'.
Some things would move out of other categories but its a group for what part do you it and another part for how.
Edible Parts:
Fruit
Flower
Bark
Stem
Leaves
*Roots
*Bulb
*Seeds/Nuts
Eating Method:
Tea
Culinary Herb/Spice
Raw
Cooked
?Fermented?
The uses of cooked greens,salad greens ,Vegetable could be converted by checking cooked and/or raw and which plant part.
Your thoughts?
