Could this rerooting of the leaf bases be because velthemia is one of the bulbs that can be propagated by leaf cuttings, as distinct from bulb cutting? Several bulbs that have strong mid ribs, such as lachenalia and galanthus, can be propagated in this way, but I would expect each "leaf" to eventually produce a new bulb, or bulbs, rather than the whole original bulb being reformed into one.
