Allen, very nice blooms! Yours have more red than mine do.
They seem to be self-sterile, so be sure to store some pollen. I may have some rather old graminicola pollen still in the freezer if you want to try it. (E-mail me your postal address if you want some pollen, at
jshields@indy.net)
My graminicola, grown in pots, do not bloom reliably here in central Indiana.
Check the leaf width, since that is one trait. See my web page at:
The Amaryllis Family: Genus Crinum
Regards,
Jim
