I found this trio of new weeds around the garden this week.
Hairy Bittercress (Cardamine hirsuta, #454), popping up between the paving slabs is an unassuming little weed with small white flowers and leaves shaped like watercress. The leaves are edible, adding - as per the name - a bitter taste to your salad.
Cuckoo Flower (Cardamine pratensis, #453) also goes by the names of Lady’s Smock or Milkmaid. One of the main food-plants of the Orange-tip Butterfly, it is often plentiful in Spring in damp meadows, but not so widespread in my rather dry garden. It’s closely related to the bittercress, both being members of the cabbage family, and is also edible. After flowering in spring it produces seeds then dies back until the next year.
Ivy-leaved Speedwell (Veronica hederifolia, #455) is c common garden weed, originating from Eurasia and by now spread widely as an introduced species. It has a blue form and a white form, the latter being the one in my garden.
