Field observations and greenhouse studies indicated that crownvetch, Coronilla varia L., required good to excellent drainage, a pH of 6.5 to 7.0, and high levels of P, K, Ca, and Mg for rapid seedling growth and stand persistence. Crownvetch compared favorably with ‘Mansheld’ birdsfoot trefoil in rate of seedling growth. While minor cultivar differences in relative top and root growth were noted, ‘Chemun’, ‘Emerald,’ and ‘Penngih’ crownvetch all produced dense vegetative canopies 2 to 3 months after seeding. On 42 highway slopes successfully seeded to crownvetch in 27 Pennsylvania counties, areas of poor or zero crownvetch cover on upper and lower portions of the slope were more closely associated with limiting physical conditions, poor drainage, or extreme desiccation, than with inadequate fertility or low pH.
