Of course. Whichever offspring of a cultivated plant could be considered wild. Especially if the species is spreading in a wild, not managed area. Sometimes findings of new occurrences are not accepted if the new finding happens in a closed private property even if the species could have come from the outside. Maybe here we can be a little bit less strict.
PS: Is wild hyacinth the common name of Camassia scilloides?
PPS: the “restorative” status of a plant could be added among the annotations. This could provide an added value to certain observations of non-wild plants.
