sooby said:Maurice, would that (abnormal conditions) also apply to the daylily relative Chlorophytum, which also produces plantlets on flowering stems? I have a vague recollection that in Chlorophytum it is in response to light, maybe photoperiod.
The only research I have found on Chlorophytum reversion is in German and therefore not readable by me. I imagine whether its reversion is considered abnormal or normal might depend on whether the environmental effects can occur normally during natural flowering in the wild or they require "unusual" conditions perhaps associated with domestication or growth and flowering inside buildings, etc.
There are probably plant species where reversion is natural, that is, it occurs normally in "wild" natural growing conditions and locations.
