Discussion
Rydberg's Delphinium bicolor var. montanense tends to have more pubescence and larger flowers but is otherwise typical and apparently fully intergrades with D. bicolor subsp. bicolor. Often referred to as one of the low larkspurs in poisonous-plant literature, the plant is abundant on some ranges and is the cause of some livestock poisonings.
