Sorry to ask you all again for plant id's but you are all soooo good at it
The first & second one is a small evergreen tree with tiny yellow flowers in spring & the third & fourth is a perennial with almost cabbagey type feel leaves (if that makes sence!!)
also if anyone knows what the weed is underneath the tree I would be really grateful as it grows all round here & can never find what it is!! it doesn't flower just loads of heart shaped leaves that spread everywhere with really deep roots!
Thanks for reading & hope you can help
