  • Gray's Lomatium
  • Milfoil Biscuitroot
  • Mountain Desert Parsley

Comment:

Native to Western America, Lomatium's tuberous roots are edible and can be dried for grinding into flour. The edible leaves taste somewhat like parsley. L. grayi is smaller and less robust then the similar L. dissectum. Like other Lomatium it has antiviral/antibiotic properties. It serves as a host plant for Papilio indra and P. zelicaon. The UV signature is uniformly UV-dark.

 

Pollinators(2):

Known pollinators include solitary bees and flies.
