European field pansy is a small wild pansy whose flowers are mostly creamy white with a yellow center, with about as long as the petals. Native to Europe, western Asia, and North Africa, it is now a weed of farm fields and roadsides across much of the US.

Appearance

Growth form
An annual, usually 4–12 in (10–30 cm) tall, with several stems branching from the base.
Leaves
Leaves have rounded teeth. At each leaf base sits a deeply divided whose end lobe is large and leaflike.
Flowers
Flowers are about ½–¾ in (10–20 mm) across, cream with a yellow throat; the upper petals are sometimes tipped with purple. The sepals are about as long as, or longer than, the petals.
Flowering time
Mainly March through July, sometimes into August.
Fruit
A smooth capsule ¼–⅜ in (5–10 mm) long that splits into three parts.

Look-alikes

Johnny-jump-upViola tricolor

Johnny-jump-up has showy purple, yellow, and white petals that are much longer than the sepals. European field pansy has cream petals about as long as or shorter than the sepals.

Why they get mixed upThe two look alike and sometimes hybridize, producing in-between plants.

American field pansy has pale blue-violet petals that are longer than its sepals. European field pansy has cream-yellow flowers with sepals at least as long as the petals.

Why they get mixed upBoth are small annual pansies of open, disturbed ground, and both get called "field pansy."
