There’s more to sourgrass than its lip-puckering powers. Dig a little deeper with this natural dye video tutorial.
Sourgrass (Oxalis sp.) is a plant of extremes: children love its strong flavor, pollinators gorge on its abundant nectar, many adore its ability to overwhelm a field when in bloom, and many still detest the invasive qualities of some of its species. Oxalis pes-caprae, native to South Africa, has made itself comfortably at home in California, forming dense mats that outcompete native plant species for light and space.

The Loma Prieta Earthquake of October 17, 1989 did over $6 billion in damage to the Monterey Bay and San Francisco Bay areas of central California. This Naturalist Night lecture at the Santa Cruz Museum of Natural History was presented by Capitola Museum Curator Frank Perry on the occasion of the quake’s 30-year anniversary, October 17, 2019, in partnership between the two museums.
This lecture focuses on the geologic setting of the epicenter and phenomena associated with the earthquake. This video was created by Frank, combining an audio recording with the slides used in the talk. The speaker, Frank Perry, is introduced by our Public Programs Manager Marisa Gomez.
This Naturalist Night lecture was presented by Frank Perry on August 18, 2015 at the Santa Cruz Museum of Natural History and explores the early beginnings of the Museum in 1905 to present day.
