Shawn,
What I do is that when I know that all the flowers of that stalk is already dried and brown, I just cut them off and put them in a small container for further drying. Then I just shake them and all the seeds will come out.
Because of the generosity of my spatulatas, I am going to try to make a shallow minibog and sow the seeds in them and see if I can populate it with spatulatas first, then maybe I can transfer some VFTs, etc. in the future
I love spatulatas so I wouldn't mind if they are found all over my garden. We can just sell or give some off if they get too many.
By the way how old are your flowering Spatulatas again?
TTFN
