Lacy Phacelia (Phacelia tanacetifolia) is an annual plant whose lovely lavender-blue flowers are very attractive to pollinators and other beneficial insects. The flowers are bell-shaped with long stamens that protrude beyond the petals. The flowers grow in clusters at the top of the stem. The deeply cut leaves give this plant its lacy appearance. Lacy Phacelia is a valuable pollinator plant and is especially favored by bees. It also attracts hoverflies, beneficial insects that eat aphids and other pests.
Lacy Phacelia is often planted in vineyards and next to crops because its nectar-rich flowers are attractive to bees and other pollinators. It is also used as a bee-friendly cover crop on organic farms. In the garden, it does best in full sun and well-draining sandy soil. This plant has a fast growth rate. Be aware that some people can experience skin irritation after touching this plant.
