What is this new weed all over my beds?

[BerryTrifle]

Forgot to take a pic but it looks like big watercress and has hundreds of tiny, beige things that look like miniature beans or chickpeas. It's everywhere- easy to pull out but I suspect with all those little pod things scattered all over the soil it will.keep coming back. Never seen it before this year in my garden. Everything was absolutely sodden underneath it.

Any clue? I'm pretty amateur in the gardening dept!

Hairy bittercress? If so, those seed pods will explode everywhere and you’ll be swamped with it. Only solution is to hand weed all you can see before they set seed, but it’s doubtful you’ll get rid of it.
of course, it could be something else entirely.

Celandine maybe?

Thanks! Hairy bittercress could well be it. There are bajilions of those seeds! With the mare's tail I've also discovered, I'm going to be busy 😣

We do also have celandine - I quite like it!

Hairy bittercress doesn’t look like a big watercress , it looks like a miniature watercress. It’s the baby cousin of ladysmock. It has long, thin straight seedpods with tiny seeds

Actually I haven't seen any seed pods. Just hundreds and hundreds of little seeds that look like teeny little beige beans. I feel like that should make it identifiable but am clearly not using the right search terms as I'm not coming up with anything.

I think we need a photo

A long shot if you are on lime - the rare Cardamine bulbifera has little bulbils in the leaf axils which fall off and propagate. Still not larger than watercress but larger than hairy bittercress.

A photo would help a lot!

Otherwise, a much better description. Leaf size in mm, shape - simple, lobed, serrated edge, compound (made up of separate leaflets - how many?) Stem length. Height of plant. Habit, upright or sprawling. Flowers, no of petals, size, colour … and so on

Is it worth downloading the picture this app?

OK, hope this works. One of the leaves and a close up of the seeds

Oops, no pics...never done this before, hang on

Seeds

Leaves

Could they be nasturtiums?

I’m pretty sure that’s nasturtium.

Yep, I agree. They are lovely, and if nasturtiums edible too, I use them in salads.

That looks like Lesser Celandine and those "seeds" are basal tubers. Has it flooded there or have you been digging? Both are very effective means of spreading the tubers.

Bit early for Nasturtium, never mind seeds (which are pea sized and very wrinkled)

Lesser celandine and celandine bulbils.

Those leaves are definitely not nasturtiums ( leaf stalks of nasturtium join in the middle of the leaf) and the “seeds” are not the netted seeds of nasturtium.

No

😂😂😂

Chickweed?

Maybe it is lesser celandine now that i google it. We have that already but it's never been this wild and the flowers weren't there so i assumed it was something new and different (especially as its in the front garden too, which ive never seen before). I wonder whether it's because we've been later than usual tackling the garden this year so it's had more of a chance to grow!

Anyway, thanks all.
