Coreopsis lanceolata L. and Salvia lyrata L. from local (Monticello, FL) and nonlocal seed sources were transplanted into a field and maintained under low input, noncompetitive landscape conditions for 2 years. Plants of both species from local seed sources began flowering and were in full bloom earlier than plants from the nonlocal seed sources. Nonlocal C. lanceolata were larger throughout the study. Local S. lyrata were taller than nonlocal plants only when local plants were in flower and nonlocal plants were not. Survival percentage of C. lanceolata was equivalent from both seed sources, but higher for local S. lyrata compared to nonlocal, at the conclusion of the study.
