Clearing a garden. Plant ID help!

I have checked out the other ID posts and stickies and haven't been able to find anything on some of these plants.

My partner and I are clearing a garden that has been neglected.
We're happy to leave some of the more contained, beautiful "weeds" but we'd also like to ID what we can. Most are not new to us, but we still aren't sure what they're called.

Any help gratefully received.
I'll number and post as good a picture as I can.

Welcome to the forums!

1. Pseudofumaria lutea..previously called Corydalis lutea.
I love it. Often found growing in walls.
Beautiful plant...to some a weed. You decide!

Pseudofumaria lutea - Google Search

2. Thinking!

3. Looks like Ranunculus repens...creeping buttercup. Best weeded out.

4. Possibly Epilobium sp. Need flower for further id.

epilobium hirsutum - Google Search

 

Welcome to Gardeners Corner

Yellow Corydalis.

Not quite sure about the second one

Creeping Buttercup

Might be one of the Willowherbs

 

Thanks for these. Very helpful. The second one smells very strongly.
Very Herby.

 

One more! This one is everywhere!

Thanks so much. This is an amazing help.

 

Second one is Feverfew. Proper name gone for the moment.
Last one could be Alkanet.

 

Agree with Palustris...Pentaglottis sempervirens.... commonly called green alkanet, evergreen bugloss or alkanet.
It is a real thug.

If you're clearing the garden (and want to keep it clear) I'd remove them all unless any strike you as being attractive. Pic1 (Yellow corydalis) and pic 2 (Feverfew) are liked by many people, and depending on your soil, may not pose much of an issue.

Pic 3 (Creeping buttercup) - is easily dug out with a handfork but if left too long, it'll send stolons over ground (like strawberries do) and creep into your lawn, then back into your borders.

Pic 4 (Willowherbs) - hoe them them or fork out. Won't pose much of a problem now but in late summer when they go to seed, you will have hundreds or possibly thousands of seedlings cropping up everywhere imaginable for years to come.

Pic 5 - Green Alkanet - an absolute beast of a weed. The tap roots can be nearly 2 inches wide, grow to 2ft deep and are impossible to dig out when establised between paving, and can even raise paving. Either dig all these up with a trench shovel or better still, cut upper parts of the stems off to stop them flowering now or in near future and blitz them with a strong Glyphosate weedkiller. It will take a few weeks before they go 'belly up'

 

Thanks so much everyone. Really appreciate the guidance.
We'll take your advice!
