Common or field forget-me-not has hairy leaves, hence its Latin name, Myosotis arvensis, which translates as ‘mouse ear of the fields’.
Hairy bittercress, Cardamine hirsuta, reminds me of a small version of lady’s smock, Cardamine pratense. It’s one of the earliest of weeds to flower and one plant can produce 50,000 seeds.
I always think of groundsel, Senecio vulgaris, as a user friendly weed. It doesn’t have a taproot or spreading rhizomes, so you can soon clear a bed of groundsel just by pulling it up. Although it will probably soon appear again as its seeds can germinate within a week.
