 Palouse Tarweed Amsinckia retrorsa Suksd. |
 aka Rigid Fiddleneck, Rough Fiddleneck, retrose fiddleneck |
 These grow all over the Klamath Basin, but the specimens shown here are in my yard. |
 The rosettes appeared in late February/early March. |
 |
 |
 The plants in my yard lack nutrients and moisture so they are stunted and single stalks. |
 The plants by the dock at the Klamath Wildlife Reserve have rich soil and a modicum more noisture, |
 These plants are multi-branched and grow about 3-4 feet while in my yard they grow to only 6-7 inches. |
