I thought you were asking about the height of the flowers. lol! I'm glad that John is on the ball.
Maybe I just have the Sib from he!!, but the rootball on mine probably weighs at least 250 lbs now and the last time it was divided I had to bribe two large men with axes and a 12-pack+ to go at it. LOL! its roots are so tough that they won't even come back to divide it for me again.
Is anybody in my area with an axe, some muscle, and a fondness for beer?
