You're asking me?
I read somewhere this morning that you should cut the flowers off when they are done, and they may rebloom! Not sure if that is correct or not. I was hoping that you would know!
Good to know that the shorter ones are like a rebloom! Mine really just opened up today to where it looked like an actual flower, so I haven't seen anything yet that looks like rebloom. Maybe it isn't necessary to do that. I'll find out though! I'm cutting them back when they are done and will see what happens! I'll need loppers too. This is a very substantial plant, even though it's not that tall yet.
