I've not been following the thread but spotted Tony's comments about flowering and what might or might not stimulate it. It's well known in Nerine that different species initiate flower buds at different times so in N. undulata they develop during the current season's growth and in N. bowdenii and N. sarniensis they are initiated two years previous to flowering. In all cases high temperatures can cause abortion. So with these plants a year's bad cultivation can result in a dearth of flowers for a period. I evidently do the wrong thing consistently with a big pot of N. bowdenii subsp. wellsii.
