hey fata ... back in the day.. in suburbia... on a 50 by 100 foot lot.. i too dug things out ... today on 5 acres.. i am a one man crew ... i have no other option ... and i do note.. you actually use it for a purpose... it has no purpose in my yard ... and anything that has no purpose.. is commonly called.. a weed ... i am agreeing with you when you said: There are different lines of gardening thought not arguing, nor being defensive ... ken

In pic 1 I have to contradict Daisy D. That's a poppy seedling. In pic 2 the frosted furry looking plant in the centre looks like chickweed, a weed. Pic 3 is the chickweed again with possibly borage around it and Oxalis. Pic 4 is another poopy with Oxalis and some sort of rhizomatous grass.(weed) 5 looks like a speedwell (weed) 6 is chickweed again (weed). 7 is speedwell again. 8 could be Sonchus. Here's a simple suggestion. Take a leaf of any you can't identify, scrunch it up and sniff. Several of the plants you list will be scented even at the seedling stage: oregano, thyme, lavender, hyssop, peppermint, spearmint, lemon bergamot (do you mean lemon balm?) I've never grown licorice or savoury so I don't know if they'll have a scent. Yarrow will smell a bit as a mature plant but I've never sniffed a seedling!

They actually look like Ajuga to me... The leaves are a bit wide for a Penstemon. Did you plant a ground cover in this area? Ajuga spreads through it's roots under the ground, so if you check one out, that would be a dead giveaway.

Thank you I think you have nailed it- i will add a picture of the tree we have in the garden. I actually compared the leaves the other day and they were so similar just different textures I just thought it couldn't possibily be a tree as there are so many I thought it must be a weed. Sadly there is no more room for trees so I best dig them all up and thanks for the tip even the small new growth was hard to pull up so not looking forward to the larger ones!!!
