Hi Lisa, just enjoy the one in its lifetime bloom show, and then try to get seeds later. But that plant will eventually wilt, just its nature. Who knows, it may also try to make offsets too before it eventually goes.
In my area, when I first got my semps, the sudden exposure to our intense heat here, promptly triggered bolting. I did not try to do anymore surgery or attempts to cut the blooms, I just let it take its course. Helped me understand more the growth cycle of this plant.
