I've had Beverly for along time. I've moved her once. It's always taken her an extra year to bloom, but if you leave her alone, she will grow like crazy. Just thin her, don't move her or you'll loose a year of bloom. She's not in any special place, and gets kind of neglected, but she does keep doing well. Just give her time.
She's a fussy old diva who doesn't like change.
She hasn't shown any signs of rot here.
