I'm reinvigorating my garden bit by bit after we moved here 4 years ago. In the bit I was doing the autumn before last i found a tuber and replanted it in a rough patch to see what it would do. Last year it just did what you see here. No flowers.
I'm now digging out the rough patch and wondering if it's worth keeping. Plant id app just come up with any Plant that has a sword shape leaf.
Thank you.
