This plant had white flowers on it a few weeks ago and they quickly all fell off (2 days). I was wondering if maybe I am not watering it enough or too much. Can someone tell me what it is. Thank you in advance for your help.
I don't know about the climate where you are (I am in the North of England), but I have a lilac in my garden and it flowers for several weeks, so two days does seem very short. Did you have a late frost by any chance?
