Arroyo lupine blows in the wind at the Native Seed Farm while volunteers weed in the background. The first official day of spring isn’t until March 20, but many flowers on the Irvine Ranch Natural Landmarks are already beginning to bloom. Chocolate lilies have been spotted on the slopes of West Loma Ridge in Limestone Canyon Nature Preserve, Weir Canyon Nature Preserve is rich with fields of bright yellow fiddlenecks, and wild hyacinth and sticky monkey flower are plentiful along many trails in Bommer Canyon.
But wildflowers need more than just warm weather and rainfall to thrive long-term. Invasive and non-native plants can steal light and nutrients from native flora, making it harder for native species to grow. In 2012, the small-flowered morning glory – a rare, native flower that was in decline within the Landmarks – was discovered sprouting from dormant seeds in the West Loma Ridge watershed habitat restoration area. This uncommon flower was able to make a comeback in part due to the removal of invasive species; in the absence of weeds, its seeds remaining in the soil were able to return to an environment free of competition from invasive plants.
