Honeybees forage on this plant mainly for its plentiful pollen from the mustard family flowers, with supplementary nectar; peak bloom aligns with spring dearth relief in April to July. As a biennial, it does not persist year to year, so successive plantings are needed for ongoing bee support; it prefers dry, well-drained sites and full sun, avoiding overly wet winters.
