Pollination of Haemanthus

I am not sure if Haemanthus will self pollinate, but if I recall correctly
I have had single clones produce seed. If you have two plants flowering at
the same time you can rub your hand from the top of one then the other back
and forth a few times. Individual flowers of a head will become receptive
at different times so for best effect you do it over a few days. I find a
flower on the head usually produces fluffy receptive pollen and then the
stigma and style elongates after to rise above the pollen sacs becoming
receptive.
When I want to cross two particular clones and minimize self pollination, I
will remove the anthers as they ripen with tweezers, storing them in
gelatin capsules in a container with silica gel in the frig for later use.
When the stigmas and styles become receptive I will use one end of the
capsule holding the anthers to transfer pollen. Using this method I am
currently crossing Haemanthus humilis humilis 'Giant' that was the first to
flower this season on Haemanthus albiflos that is just starting its flower
period.
All the best, Michael
