Hi Uli and All,

I do not agree with you Uli.
I germinate all my Cyrtanthus seeds that way.
And seeds sunken to the bottom do almost always germinate!
Just be patient.
As long as there is an embryo!
Cyrtanthus carneus f.i. might take two to three months to germinate!
By taht time most of the seeds are on the bottom!

managed to germinate seed of overstored short lived Amaryllidaceae seeds
this way. But I would not call it the float and sink method. Seeds sinking
do not germinate. It is more float and root. With valuable seed I use
tweezers to fish them out of the water and plant them individually when the
root appears and leave the non sprouted ones floating. But I always remove
sinking seeds as they might spoil the rest. Could you feel an embryo when
you gently take a single seed between index and thumb? If not the seed may
have been empty.

pollination so may be the seed set of your plants was not viable as already
commented.
