1. + 2. is Sweet Vernal Grass -
Anthoxanthum odoratum. This is the grass that gives 'new mown hay' that lovely smell.
3+4. is Ribwort Plantain -
Plantago lanceolata. This is not a grass but a common flowering plant.
I have added the
latin names. I don't expect you will remember them, but if you keep saying them, along with the common names, they will eventually stick, and will prove very usefull if you intend to take a keen interest in plants.
And Donola, feel free to post as many plants as you like. After they have been identified, it is a good idea to then look them up and read about them and then if possible to go back to the plant and take another look, and just keep saying their names. I can promise you that wild flowers are one of the greatest interest you can have, (in my opinion

)
