Phacelia (Annual Phacelia), also known as lacy phacelia, or blue/purple tansy, is a quick-growing, flowering plant that can reach heights of up to 4 feet.

It was originally native to the Southwestern United States and northern Mexico but it is now used in many places in as a cover crop. It is superb for bees and honey production. 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..
