Lomatium utriculatum

Spring Gold or Biscuitroot is a widespread spring perennial from British Columbia south into northern California. In our area it occupies steep slopes and delights in mid-late spring with complex umbels of brilliant gold/yellow flowers. This tap rooted plant requires regular water for the first season- but never boggy, In enriched to average well drained soil. Excellent performance on slopes. Over time the rosette increases in width and amount of spring flowers. Adapted  to life between native clumping grasses. This is easily replicated in a garden. An important native pollinator plant that was also used by native Americans as a food source. To 6″ tall in bloom a plant will achieve 2′ wide in half a dozen years. Strongly resents disturbance and a happy plant will live for decades. Not bothered by pests. Once native in the Portland area, its original range in W. Oregon has been substantially diminished. Great companion plant with Manzanita. Goes quietly dormant over summer. Occurs with both Camassia leichtlinii and quamash, as well as Ranunculus occidentalis, Plectritis congesta, as well as Dodecatheon. Moderately deer resistant.
