Distribution of Field pansy
Distribution Map
Field pansy is a plant with a broad natural range in temperate regions of Eurasia. Its presence extends to northwest Africa, but it has also been introduced to other continents including South America, Oceania, and North America, thus adapting to diverse climates and habitats in both its native and non-native regions.

Toxicity
The field pansy plant, particularly its seeds, is mildly toxic to humans, cats, and dogs. Ingesting large quantities can cause gastrointestinal issues like vomiting and diarrhea. Alkaloids in the entire plant are responsible. Prompt veterinary care is advised if pets consume field pansy.

Field pansy is native to Europe, northern Africa, and western Asia. This species is frequently cultivated for its ornamental uses and it also provides resources for pollinators and wildlife. However, its propensity for self-sowing can result in field pansy become weedy or even invasive in some areas. As such, it is considered invasive in at least 12 countries and some states in the United States. It grows readily in disturbed areas, including fields and roadsides. Removing its flowers before the plant goes to seed can prevent further spread. Herbicide can also be effective in controlling unwanted populations of field pansy.
How to Control It
The best time to remove field pansy is during late spring or early summer before the plant has had a chance to produce seeds. Here are some methods to control or remove field pansy:
Hand Pulling: Wet the ground to loosen the roots, then simply grip the base of the plant and gently pull to remove the entire plant from the ground.
Smothering: Cover the area around field pansy with heavy-duty garden fabric or plastic sheeting. Secure it in place and leave it for a few weeks. This method suffocates the weed and halts its growth.
Solarization: This is effective in hot, sunny climates. Lay clear plastic sheeting over the area, burying the edges in the ground to trap the heat from the sun. Leave it for six weeks for the heat to kill field pansy.
Vinegar: Spray a solution of 20% vinegar and water on field pansy. This solution acts as a natural weed killer.
Crop Rotation: Plant different crops year to year that compete with field pansy for resources.

Water:
Originating from temperate regions, field pansy adapts well to moderate moisture. It thrives with weekly watering to maintain soil moisture, requiring more frequent irrigation during dry spells to mimic its natural habitat. This resilience reflects its ability to cope with varying water availability.
Fertilize:
Use slow-release commercial compound fertilizers for field pansy. During growth and bloom, apply thin compound liquid fertilizer every two weeks. For specific application methods, consult the product specifications for the compound fertilizers.
Propagation:
Certain varieties of field pansy are self-pollinating, producing fruits post-flowering that split into three petals when ripe. At this stage, seeds can be harvested for sowing in the next year.
