The plant has a coating of gray hairs. The leaves are each made up of three spine-tipped leaflets. The inflorescence is a head of several flowers which are cream-colored with tinges of pink or purple. Blooming occurs in June and July.[3] This plant grows in soils of decomposing tuff, a volcanic ash substrate. The plants grow in cracks in the soil, so that they can appear to be growing in a straight line. There is little other vegetation in the habitat, but associated plants may include Artemisia arbuscula.[2] This plant may have a disjunct distribution, but it is possible more populations occur in the 300 kilometers between the two population centers in southern Oregon and northern Nevada.[3] References1. ^{{PLANTS|id=TRLE|taxon=Trifolium leibergii|accessdate=15 December 2015}} {{Taxonbar|from=Q7841533}}2. ^1 Trifolium leibergii. {{Webarchive|url=https://web.archive.org/web/20111026070412/http://www.centerforplantconservation.org/Collection/CPC_ViewProfile.asp?CPCNum=4325 |date=2011-10-26 }} Center for Plant Conservation. 3. ^1 2 Trifolium leibergii.
