Phacelia: The Garden Plant That Feeds Bees And Fixes Soil

- Phacelia tanacetifolia (also known as fiddlehead) produces five-petalled flowers rich in nectar and blue pollen, drawing hoverflies, honeybees, parasitic wasps, solitary bees, and bumblebees to the garden.
- Susie White keeps a ready packet of phacelia seed to direct-sow into bare soil among vegetables and ornamentals, using it as a green manure that suppresses weeds, captures nutrients, improves drainage, and conditions the soil.
- In early May, White sowed phacelia in a mid-height border gap left after removing vigorous Michaelmas daisies, where she plans to plant biennial cotton thistles (Onopordum acanthium) that will tower above her head next summer.
- At farm scale, phacelia forms an "eye-soothing haze of purple" with a high nectar yield that supports millions of insect lives, according to White.
- Karl Blossfeldt's 1928 black-and-white photograph captured the plant's coiled, unfurling "fiddlehead" flower structure with "startling clarity," exemplifying the patterns and symmetry of plants that White says she first noticed while sketching the sprig in her sketchbook.
Why it matters: For gardeners, the pitch is concrete: one packet of phacelia seed, direct-sown into bare soil, replaces multiple jobs — weed suppression, soil conditioning, and pollinator feeding — that usually require separate interventions. At field scale, the same plant supports what White describes as 'millions of insect lives,' making it a rare case where garden-scale and farm-scale benefits align in a single low-input species.
