This plant is popping up in a few places in our garden.
Seems to be spreading it self quite fast.
I like the black patterns on it's leaves.
But would like to know if it's a good plant to keep.
Many thanks for having a look ;)

Knotweed (Persicaria). In my opinion, not worth keeping.

Thinking, based on Tiffany's identification, it's Persicaria maculosa (lady's thumb), an invasive annual weed that has a deep taproot and spreads by seed.
https://en.wikipedia.org/wiki/...

I do accept that there's some terrible weeds in the Knotweed family (including in the Genus Persicaria).
Still, I have found several horticultural Persicaria cultivars very easy to maintain. I particularly like Persicaria amplexicaulis 'Firetail' (at least here) at the back of mixed perennial beds.

Thank for everyone in identifying this weed.
It will be removed asap

Sunnyborders, I do like the Persicaria amplexicaulis.

Happy gardening everyone Thumbs up

Named cultivars are often sterile, hence their appeal. Smiling Since yours is a volunteer, it's quite virile and will make more if left to do so.

I've never met a volunteer plant bearing a chevron on its' leaf that I wanted to cultivate. I've asked in forums a few times over the years and have never had anyone add a plant they did want to cultivate. This formula seems to be universal: Volunteer + chevron = weed.

Happy to suggest & share previous experiences! Bringing up such an idea periodically also gives me a chance to learn a possible new plant, if such thing as a desirable chevron-bearing volunteer exists.

Dropped seeds are the biggest enemy, as far as prevention of unwanted seedlings goes. As you prioritize ID'ing/removal, always be on the lookout for blooms. They are the feature that's most diagnostic on most plants, and, of course, soon after blooms fade, there are the seeds, ready to fall & repeat the cycle. If plant is removed before they fall, one can get a grip on breaking the cycle of that plant showing up in troublesome amounts. There will always be seeds already in the ground that can sprout for various reasons, but preventing the dropping of more is crucial to maintaining some control, IME.

As many mystery plants as you have are welcome, somebody should recognize them. It's always less confusing if you do a separate discussion for each kind.
