It is a perennial herb growing from branched and tuberous roots[1] in the form of a caudex. The erect stem averages about 18 centimetres (7+1⁄8 in) in height.[1] There are a few oval to lance-shaped leaves.
The inflorescence is a dense, often crowded cluster of hanging tubular flowers which are fused at the base and expand into lobed and bell-like mouths.[1] They are generally bright blue, but may be lavender to pinkish to nearly white, and measure up to 2.5 cm long.
