Butte County meadowfoam sprouts up along the edges of vernal pools that come back to life when the winter rains return to northern California. The seedlings can tolerate short periods of submergence underwater and eventually develop into rosettes, which do not begin producing flowering stems immediately. Flowering typically begins in February, reaches peak flowering in March and may continue into April if conditions are suitable. Floral adaptations allow for cross-pollination by insects, which are attracted by the large flowers and production of nectar. The flower also has self-pollination mechanisms which support seed development if insect pollination is unsuccessful.

Butte County meadowfoam is found in seasonal wetland habitats such as the edges of vernal pools. It generally grows on level to gently sloping terrain, on poorly drained soils with shallow layers of hardpan clay that create a pool of water. It thrives in waterlogged soils and tolerates being submerged in water for short periods of time.

The species is restricted to a narrow 25-mile strip along the eastern flank of the Sacramento Valley from central Butte County to the northern portion of the City of Chico. While the plant’s range has not changed, the number of populations, as well as the area occupied and the amount of available habitat within the range, have declined significantly in the last 30 years. This is mostly due to urban development in the area.

Butte County meadowfoam is a small plant with white flowers that grows in seasonal wetlands along the edges of vernal pools.
