I have a horrible feeling that is Mind your own business. Soleirolia soleiroli. If it is then it is a total take over thug.

Hywel posted a photo of this plant growing in a pot. Take a look at it Kate.

I agree it is Soleirolia and if it is I 'd take it out or it will take over your garden. My middle brother [the none gardener] bought one 5 yrs ago and is now spraying with glyphosate regularly to eradicate it.

Yes as Shirley has said I posted a photo of it recently and you clicked the 'like' button for it Kate.
Although it is a pretty little plant I would put it in a pot, because it spreads quite a lot and can become a nuisance.

I love this chartreuse color. Maybe you can contain it somehow.

Thanks everyone for your feedback, much appreciated. Oh dear, it sounds a prolific nightmare! What a pity. Yes, I remember liking it Hywel, I thought it may have been the same plant. Wasn’t too sure. I liked the pretty little leaves and the lushness, but, I’ll have to rethink this now. ☹️

You could keep it in a pot like I do :)

Hi Hywel, sounds a plan. Your pic of it in a pretty colourful pot looks effective.

Thank you … I hope you can find a nice pot for it :)

Thanks Hywel, it gives me a good excuse to go garden centre shopping! ;)

What could be better :D

Sometimes people who have a Japanese garden (or Japanese area) use this as ground cover as it spreads more quickly than moss. I like it!

Hi Sheila, my OH really likes it too. He’s keen for it to spread all over. His rationale is; the rockery is quite long and steep-ish and after many years of trying out lots of plants, he thinks this may be a solution...

Thanks Julia, I’ll give it a go and keep a beady eye on it. I suppose I may be able to transplant some of it to other areas..

If it likes your garden it will cover it. so plant with caution would be my advice.

Thanks Eileen, I appreciate your advice.
