Lacy phacelia (Phacelia tanacetifolia), also known as blue tansy or purple tansy, is a captivating addition to any garden. This annual herbaceous plant is celebrated not just for its stunning visual appeal, but also for its multitude of benefits to gardeners and farmers alike. Let’s delve into the unique characteristics, blooming patterns and myriad advantages of planting lacy phacelia, while uncovering some fascinating facts about this remarkable plant.

The Enchanting Elegance of Lacy Phacelia

Lacy phacelia boasts delicate, fern-like foliage with finely divided, lace-like leaves, which give the plant its “lacy” moniker. Its most striking feature, however, is its beautiful inflorescence. The plant produces curled clusters of bell-shaped flowers in a vibrant purple-blue hue, each with long, protruding stamens that add an ethereal touch. The blooms form in a coiled cyme, unfurling gradually to reveal a succession of blossoms over an extended period. This makes lacy phacelia a continuous source of visual delight in any garden setting.
