Identify & advice please
First of all, I didn't plant these they were there when I moved in to my new house just under a year ago.
In the summer I had some tall grass that first of all had bright orange flowers. They fell off and a couple of weeks later beautiful purple flowers appeared. I have no idea what this is, I was told it could be crocosmia but when I search it doesn't mention anything about purple flowers. Does anyone know what it is? Next question, now all the grass is dead what should i do with it, I want it to hopefully come back.
Thank you in advance for any help and advice
