Fields of Yellow: Invasive, Non-Native Black Mustard Plants Seen Throughout the Conejo Valley

It has been a beautiful ride this winter and spring, watching the hills turn from golden brown to lush green and now the deep yellow color of the invasive black mustard “weed” that has sprouted more than typically seen throughout the Conejo Valley.

I’ve walked through 8 foot tall mustard plants in the Hillcrest Open Space and seen the hillsides in Calabasas blanketed in yellow in the past several weeks. While stunning to see, these non-native plants prevent germination of native plants. Let’s hope our local agencies and organizations can clear out much of this growth before we reach peak fire season later this year.
