Walter Kaiser collects taper-tip onion (Allium acuminatum) along the Snake River in Idaho in 2005. Collections were made across a broad area of Western rangeland to strengthen the WRPIS Allium collection and for research to determine taper-tip onion adaptation zones needed for successful revegetation.
