hi,

Please help.
These ones i found in my garden but no idea what they are...
Whether they are wild or garden varieties.

1a. Is this possibly fleabane?



1b. close up of (1a)



2a. not flowered yet i think.



2b. close up of (2a)



3a.



3b. closeup of (3a) - looks like just started to flower.



4. is this some sort of cress or rocket? only 3 inches at the moment.



As i said they are all found in my garden so must be very common.

[aeshna5]

1 Guernsey Fleabane, Conyza sumatrensis
2 Early Golden-rod, Solidago gigantea
3 Annual Mercury, Mercurialis annua
4Hairy or Wavy Bittercress, Cardamine hirsuta or C. flexuosa (can't see enough detail to be sure, though leaning towards latter)
