Maybe, just maybe she didn't realize it and screwed up. I've screwed up plenty of flowers and stuff in my garden and sure in the heck didn't do it on purpose. And time of year to trim, transplant, etc.? Shoot, I've been known to ignore that and my garden is just fine. lol

They will grow back and if they don't ask her get you new ones for next year. It is special to you but in the grand scheme of life it really isn't worth causing tension in the relationship over. I am sure she meant no harm based on what you said about talking it out. If my Jim yelled at me about a bush I'd look him straight in the eye and tell him I am very sorry but it's not worth us being angry with each other. It's a plant and can be replaced or come back to life.
