Pretty Flowery Plants I Cannot Identify

Loopz

Could I have some help please ID'ing these. The yellow comes up every year but doesn't spread too much.

The pink (pic 2 & 3) is in a newish bed I started last year. It is close to a penstemon and between the two are loads of seedling that I cannot tell if from this or penstemon (I'm sure the former as never remember having penstemon seed like that). While the pink is pretty, I'm a bit worried it might be invasive?


Thank you

The yellow is Yellow Loosestrife, Lysimachia punctata.

The pink is a weed,  a small willowherb that will seed itself everywhere if you don't get it out right away!

Thank you Buttercupdays, willow herb dug out during the last of the evening sun and I will keep my eyes peeled for the seedlings.

Have read up on the loosestrife, apparently it likes boggy or woodland areas, it comes up every year on some very dry sandy soil! I like it as do the bees, but I think I will move it around by the trees as it's taking up too much space in my 'kitchen window' bed.

Thank you once again!

It's a bit too bright a yellow for my border, but I keep some there as it's such a willing plant and can be relied on to make a show.

If you put it somewhere damper it will spread much faster. It's almost impossible to kill, I have some that has survived two years after being dug up, just sat on concrete, winter cold and summer drought!
