Hairy Bittercress (Cardamine hirsuta) is a common weed of gardens, greenhouses, paths, railways and waste ground. It is a plant ideally constituted to be a weed - it likes disturbed ground and bare soil; it can grow from seed to a plant shedding seeds within three weeks; it has pods that explode sending the seeds a distance from the plant; and the seeds can remain viable within the soil for at least ten years.
I wonder how many gardening years of work are spent getting Hairy Bittercress out of our gardens?
10 years!!! My garden must contain thousands of the seeds. At least they're an easy weed to pull up. Speedwell looks so innocent, but I invariably snap it off without removing the root.
