Veronica agrestis aka Field Speedwell
Taxonomy
Veronica agrestis, also known as green field speedwell, is a flowering plant in the family Plantaginaceae. It is an annual plant that can grow up to 0.1m (0ft 4in) and is found in cultivated ground throughout Britain, common in the north, and local in the south. The plant prefers well-drained soil with a suitable pH level of acid, neutral, and basic (alkaline) soils. It cannot grow in the shade and prefers moist soil. The plant is hermaphrodite and is pollinated by Dryoptera and hymenoptera. It is also self-fertile. However, Veronica agrestis is considered invasive in Alaska and West Virginia. Green Field Speedwell is a super rare houseplant that thrives with regular watering, prefers long-lasting, direct light, and should be less than 1 foot from a window. It likes well-draining soil and does not need added fertilizers if repotted each time it doubles in size.
Common names
Field Speedwell, Green Field Speedwell, Procumbent SpeedwellHow to care for Field Speedwell
Difficulty
Even if you don't have a green thumb, you can successfully care for Field Speedwell due to its easy-going nature.
Water
Field Speedwell should be watered regularly, allowing the soil to dry out between waterings.
Soil
Field Speedwell 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.
Lighting
Field Speedwell 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 Procumbent Speedwell.
Toxicity
The toxicity level of this plant has not been officially confirmed by Ploi. If there is a possibility of ingestion of plant material with an uncertain toxicity by you, a family member, or a pet, it is advisable to seek the assistance of a medical professional.
Fertilizer
Repotting the Field Speedwell is necessary either when it has doubled in size or once every year, whichever happens first. With fresh potting soil replenished annually, the plant will receive all the necessary nutrients, rendering the use of fertilizer unnecessary. Keep in mind that the source of a plant's energy is the sun, not fertilizer.
Region of origin
Field Speedwell’s native range is Europe, including Britain, from Norway south and east to N. Africa, W. Asia.
