Expanding range in mountainous areas and in the central-western region. Common in the Central- western and Southwestern regions. Uncommon in desert regions. Reproduce by seed . Seeds fall near the parent plant or are dispersed to short distances with wind and to greater distances with human activities, animals, water, and soil movement.
Most seeds germinate after the first fall rains.
Plants exist as basal rosettes through winter and early spring until flowering stems develop in late spring or early summer. Large plants can produce nearly 75,000 seeds. Some seed is viable 8 days after flower initiation. Most seed does not appear to require an afterripening period. Seed germination is closely correlated with rainfall events.
