Pest Details

Field Scabiosa

Origin:

Introduced from Europe as a garden ornamental, but a common escape that is found along roadsides, rights of way, or in other disturbed sites. Now found throughout the northern half of the United States and southern Canada.

Biology:

An annual or short-lived perennial that reproduces from seeds. Not a serious weed problem, but plants can grow fairly large and may be a problem when growing where not wanted.

Identification:

Mature plants may be as tall as 3 feet, with several stout stems and multiple branches from these. Leaves are elongate but deeply lobed into 5 to 7 long, narrow lobes that almost separate to the mid-vein. Most of the leaves are clustered at the base, with some also alternate along the stems. Flowers are pink to violet to bluish, and form a flattened , round head of many individual flowers. As the seed pod matures it becomes an egg shaped, bristly pod.

Characteristicts Important to Control:

Not generally a problem weed, and physical removal can effectively eliminate it.
