Bittercress (Cardamine hirsuta) flowers occur in terminal
racemes, with each flower having 4 white petals.
Unlike many plants which must grow to a certain point to reach
maturity and flower, bittercress can develop flowers while very small.
Flowering at a small size often occurs when bittercress are under
stress, which is common during the warm summer months.
This ability to flower at a small size is another reason bittercress
is difficult to control. It has been said often that "if you
pull weeds before they go to seed, you can stop the next generation
from germinating and perpetuating the problem". Because bittercress
flowers at such a small size, hand pulling before the plant goes to
seed is challenging.
