PURPLE TANSY Phacelia tanacetifolia
Phacelia tanacetifolia is an annual that grows erect to a maximum height near 100 centimeters (39.37 inches) with none to a few branches. The dense and hairy flowers are curving or coiling of bell-shaped flowers in s of blue and lavender.
Phacelia tanacetifolia is native to Southwestern United States and northwestern Mexico. It is most common in the deserts of southern California below 5,000 feet (1,500 m), but may be occasionally found at much higher elevations.
It is used outside its native range in agriculture as a cover crop, a bee plant, an attractant for other beneficial insects, as a green manure and an ornamental plant. It is planted in yards and alongside crop fields, where it is valued for its long, coiling inflorescences of nectar-rich flowers which open in sequence, giving a long flowering period.
It is a good insectary plant, attracting pollinators such as honey bees. It is also attractive to hoverflies (family Syrphidae), which are useful as biological pest control agents because they eat aphids and other pests.
