I believe once a cross takes whether you pollenated one lip or all three it's
over. But what I was saying is you have to pollenate all three lips to have
seed in all three chambers. I do not believe once a cross is made and takes
that a bee can pollinate that flower again. Course I am not an expert. Why
don't we do an experiment next spring all of us pollinate 2 flowers but only
one lip but leave the iris petals on to see if you have seed in the other
chambers.
