AbstractExamines the effects of differing soil conditions on the growth and competitive ability of two ecotypes of Achillea millefolium. Plants from both serpentine and zonal soils grew larger in serpentine compared to zonal soil. While zonal plant grew taller than serpentine plants when grown in zonal soil, zonal plants did not exhibit increased competitive ability. Although ecotypic variation has occurred between these two population, there been no apparent trade-offs between responses to the physical environment and competitive ability.
