A "bump" I suppose. I have some crocosmia of an unidentified variety (the label being long lost into the soil). I like them because they refuse to die. On the other hand, they never seem to do much flowering either.
I leave them because they grow back every year and I have more important things to do than annoy them. They neither spread not die.
I notice them when they bloom briefly and admire them for that. Otherwise, they don't get in my way, nor I in theirs.
They accept what little watering I give them in Summer and do not demand more. I suppose they would do better with more attention, but not demanding it, there always seems to be others needing more, so the others get it instead of them.
I would be sad if they did not return some Spring, but not terribly surprised. But they will always come up, I guess, There are some plants that just ... linger... on their own. Happy where they are. Not asking for any special attention...
We could all learn a lesson from them.
