I go through the "0" replies every now and again and found this one...hope they didnt give up on us. Sometimes they just get missed.
The part where the flower was is totally not daylily, but thats the closest I could come with the knowledge I have :)
I also thought 'Agapanthus' seeing the thick leaves and the large roots. Perhaps one of the stiffer, not so arching ones, or maybe that is just because it is lying on its side. The flower attachment looks like it does not have enough flowers, but does have that 'Agapanthus' look.
some of these folks don't come back- or try the forums more closely related to their plant. Such as the Australia forum...where the experts are in their region...agapanthus works for me, this is another OLD thread. At a time our forum members were busy making a living and weren't on as often...
