My Sarcaulon has by far become one of my favorite plants even surpassing my new Brighamia. I noticed today the I believe it has begun to set seed. One of the flowers has lost all of its petals and has a large growth. How can I hand ploinate some of the other flowers. Also how can you tell when the seeds are ready to be harvested and does the plant shoot off it seeds or anything I should be aware of. these may be odd questions but I do not know the ones to ask.
