Plant or weed?

[elephantskiss]

Hoping someone can help! The first is springing up in my border and I think sometimes has tiny white bobbly flowers. Not sure if it's spreading from something I've planted or a neighbour's plant, or if it's some kind of invasive weed! The other is some kind of bigger plant or weed, I'm not sure, but I'm worried I might not have planted it and it might have been self-seeded from the nearby trees as my neighbour has always warned me not to let those grow but I'm not sure what they look like when growing! I just can't remember half the this I've planted over the years!

The one on the left looks like it might be a kind of euphorbia. Mine gets lime green flowers on. Some people like it but it does spread really quickly. The sap can be an irritant so I’m trying to get rid of mine (Young kids) but as fast as I dig up one bit, another clump seems to appear somewhere else!
The one on the right looks like a winter flowering heather. Cut it back now and you’ll have lovely flowers again next winter.
I’ll caveat all the above by saying that I’m a very amateur gardener and if someone else comes along with better advice please take it!!!

The second one is indeed a heather, Erica. The first one isn’t Euphoria, it could be Sweet William, I planted several last year and they look like your plant at the moment.

Thanks for your replies! The first is neither Euphorbia nor Sweet William, after looking at pictures online. The flowers are very different and I have (what I now know to be) Euphorbia further up the garden!

Glad the second is heather. Sounds like something I'll have picked up for 50p at a plant sale and forgotten about!

first one possibly sweet woodruff. best way to see is pick a stem and bring in house. Smell the next day- if is smells sweet and lovely then it def is

I have this growing in my garden and pick lots of it before it flowers and make it into a cordial. Lovely with sparkling gin water

Yes gatekeeper - you could be right. The leaves are clearly in whorls, which more or less pins it down to bedstraw family (or martagon lily, which it isn't) and of the bedstraw family, woodruff is the only one that fits.

Thanks! At first, I didn't think it matched Sweet Woodruff either, but now some flowers have fully opened, I can see it definitely is. And given it is used as ground cover, it is exactly what I need in this spot (to prevent unknown weeds coming through so I don't have to keep having to figure out what's there!).

cut some and bring it in the house- it smells wonderful the next day- better than any air freshener
