Castilleja purpurea var. citrina, Lemon Paintbrush, shares most of the characteristics of its species, C. purpurea (Prairie Paintbrush), but has yellow floral bracts and a longer and more flaring lower corolla lip than varieties lindheimeri and purpurea. It is a grassland perennial found in gravelly or sandy limestone soils from central Kansas to central and west Texas. Like many Castilleja species, it has adapted to its prairie environment by becoming semi-parasitic on grass roots, so planting it alongside prairie grasses would be ideal for it.
