What plant is this?

[ChatterMonkey]

Pulled this up while weeding around my newly planted lavender, once i pulled it out, the roots didnt look like any other weed ive pulled out, is it a weed or is it a 'something' plant?

My knowledge of gardening is non existant but i really want to try and learn enough to have a nice front garden!

I can't see a photo

Cant get the photo to attach!

Here

Can you take a pic upright with the leaves on show,

Looks like mint? Does it smell?

Ive already popped them in the recycling bin no obvious mint smell to it but i might have just not noticed i suppose.

If it was mint where would it have come from?

Looks like a weed with runners that’s come in with your lavender plant. Could be ground elder. Just get rid of it.

See that you have binned it. Good.

ground elder? Can eat the young leaves

apologies Beebumble2 cross post. Yep - very invasive

Ahh so it piggy backed in the pot with the lavender and then took root once in the ground? It did sprout very close to the lavender so would make sense.

Looks like Peony leaves

I agree it looks like peony leaves to me. They are starting to shoot at the moment... a shame if so as they're beautiful! The leaves and root are different to ground elder, in my opinion. Latter's root is all white - I've dug some up from my garden; see attached.

That looks like some type of mint to me also.

Ground elder has red stems..... One side of my drive is covered in it 😭

My plant app also thinks it's a peony

I thought peony when I saw it too. They have more of a tap root than a fibrous root system.

I split and moved one because of building work and some small shoots have sprung up in places alongside the planting area. They're tough survivors - but not if they're in the bin, sadly.

Ah if its peony i wish i had kept it! If another one sprouts, would it work to pull it put and plant somewhere else? Or would it not survive the movement?

It was so close to the lavender that it wouldnt have been sustainable, but it would be nice to have a peony plant in another area of the garden!

It'd survive.
I found one growing in a pile of discarded 'diggings' that I'd, not at all carefully, shoved in a shady corner.
Just give it a bit of space.

It looks like a runner so definitely not a peony (which have thick tubers not fibrous roots)
I think it’s ground elder, I have plenty here if you’d like some more! It gets reddish stems when it’s mature.

I am saying peony too.

@CombatBarbie I'd get some ammonium sulphamate on that ground elder. You can buy it on eBay and similar. (Check out the reviews )

Technically, it isn't licensed as a weedkiller by the EU, it's sold as an additive for compost to accelerate decomposition. It used to be widely used as a weedkiller in the UK, before EU regs came in forcing greater product testing that the manufacturers couldn't afford. So it is currently unlicensed (and part of the process involves forcing it on laboratory animals until they die to work out the lethal dose), and intended for compost acceleration only.

Obviously, if you make up a watering can of it and accidentally trip up and put all that ammonium sulphamate all over the ground elder, then that's a terrible whoopsie, isn't it. I accidentally spill some on brambles and nettles when they crop up, within a week they're toast and no harm done to the soil or surrounding area. It's very safe in ordinary use (unless you have cells with chlorophyll).

Looks like bleeding heart to me?

This

We can't tell a lot from that photo, but I think we can safely say:

It's not a conifer
It has compound leaves (ie leaves composed of several leaflets)
it has alternate leaves (as opposed to leaves in pairs on opposite sides of the stem; or leaves coming out in whorls around the stem)

The is enough to definitely rule out mint, which has simple leaves in opposite pairs.

From general "jizz" I'd go with ground elder.
