Some Almost-Edible Bulbs

Here we have a group of Watsonia and lily bulbs, some of which are approaching a stage of edibility. Lily bulbs for the most part are provided with a bitter principle, to protect them from insects and various subterranean marauders; but some species are much less bitter than others, and it would doubtless be possible to get rid of the bitter principle in time, by careful selective breeding; and an edible bulb might result. There are numberless undeveloped possibilities of improvement along these lines among the bulbous plants.
