Biscuitroot (Lomatium roseanum)
Description
Roots range from woody taproots to more fleshy underground tuberous-thickened roots. Most lomatiums are desert species or grow on bluffs where water is limited for most of the year. They are green and grow the most during the spring when water is available, then set seed and dry out completely above ground before the hottest part of the year, while storing the energy they gained from photosynthesizing while water was available to them in their deep roots. For most of the year, the plant is not visible; the brown tops often are blown off or easily crushed, but it lies dormant underground for the next spring.
