Rough popcornflower

The Rough popcornflower (Plagiobothrys hirtus) is a herbaceous plant belonging to the Boraginaceae family. It is a rare species native to the United States, specifically restricted to the state of Oregon where it occupies very specific environmental niches.

The plant is typically found in vernal pools, wetland margins, and seasonally flooded lands. Its primary habitat requirements include high soil moisture levels and stable water tables during the active growing season, making it highly susceptible to habitat degradation.

Botanically, the species is identified by its rough, hirsute foliage and delicate inflorescences. This distinct hairiness is an adaptation that helps the plant thrive in its unique, often humid, environmental conditions.

Regarding soil requirements, this species favors heavy, silty, or clay-rich soils that retain water well. It does not tolerate drought or total soil dryness, which limits its ability to grow outside of its protected wetland habitats.

Due to its status as a threatened or endangered species, the Rough popcornflower is not a crop in the traditional sense. It is not used for agricultural production, and all efforts regarding the plant are focused solely on species recovery and ecological conservation.
