Many farmers have used Phacelia (Annual Phacelia) as a source of high quality nectar and pollen to increase the population and diversity of beneficial insects for their crops.

Long, coiling inflorescences of nectar-rich flowers open in sequence, giving a long flowering period. It blooms mid-late summer when other blossoms have disappeared. It is an attractant for beneficial insects and an ornamental plant. It is a good insectary plant, attracting many pollinators. It is easy to plant, has excellent germination and does not require inoculant, thou inoculant will increase germination and speed the growing process..
