Thlaspi arvense aka Common Penny Cress

Even if you don't have a green thumb, you can successfully care for Common Penny Cress due to its easy-going nature.

Common Penny Cress should be watered regularly, allowing the soil to dry out between waterings.

Common Penny Cress loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Common Penny Cress thrives in bright and direct sunlight. To ensure your plant receives enough light to survive, place it less than one foot from a window. The current weather in your area may affect the placement in your home. For example, if you live in a region that has longer and more intense periods of sunlight, then you may want to place the plant farther away from the window to avoid direct sunlight and reduce the risk of sunburn. Alternatively, if you live in a region with relatively milder temperatures and less intense sunlight, then you may be able to place the plant closer to the window for increased exposure. Ultimately, the current weather in your area should be taken into consideration when determining the best placement for your Bastard Cress.

During the wintertime, it's common for Common Penny Cress to go dormant and their growth may slow down, so waterings should be spaced out more.

Common Penny Cress is poisonous if ingested. We suggest keeping this plant out of reach if you have children, cats, or dogs in the home.

Common Penny Cress grows vertically and new growth emerges from the top of the plant.
