Persicaria maculosa (Redshank) - keep or not?
I've been waiting to see what a mystery plant growing in the borders is, and now the leaves have come through sufficiently, I have been able to identify it as Persicaria maculosa. Looking this up online, it looks like it can also be considered a weed.
This plant is completely new to me, and is something that has popped up without being planted. It already looks pretty vigorous.
Is it worth keeping, or will it turn into a nightmare and seed/run everywhere? Is it any good for wildlife (primarily pollinators & insects), which is what I try and aim for with the garden.
I know nothing about this one at all, but if it is likely to be a nuisance with no wildlife value, I'll hoik it out as there's plenty else I can put in its place. If it will have wildlife value, I'll leave it in.
