Currently the tag bulbs is mostly associated with "Onions", a bulb vegetable that is strictly speaking a subset of "Root Vegetables".
Personally when I think of bulbs in a gardening context, the first thing that comes to mind is Springtime bulbs (flowers):
Crocus.
Daffodils.
Tulips.
And other flowering plants like:
Iris.
Lilies.
Daylilies.
Personally I think the tag bulbs would be better served if it was associated with flowering type plants (as per above).
Additionally it might be worthwhile to make "bulb-vegetables" a synonym of root-vegetables
Q. What are other peoples thoughts on this, do you agree or disagree?
Q. Is there a better way of handling these kind of conflicts?
