Discussion | Aquilegia flavescens sometimes forms hybrid swarms with A. formosa var. formosa, which grows at lower elevations through much of its range. Intermediate specimens having pinkish red flowers and petal blades 5-6 mm are occasionally found where these species grow together. The name A. flavescens var. miniana has sometimes been mistakenly applied to these intermediates, but the type of var. miniana is a typical, pink-sepaled plant of A. flavescens.
