There are a couple of forms of this. ssp. campanularia that grows in the S.E. Calif. desert. ssp. vasiformis grows in the middle desert. The trade does not recognize either and only sells the species. This is a 1-2 foot annual with royal blue 1 inch flowers. It is very showy in interior heat. Use with Baileya, Lasthenia, and Nemophila menziesii. Desert Bluebell is super easy to grow in hot sandy areas. Loved by Sphinx moths.
