Recently, if you’ve ever had the chance to explore the coastal areas of Northern California, such as Half Moon Bay or Pacifica, you’ve likely come across cliffs adorned with striking purple and yellow flowers. While they may appear stunning, these blooms actually belong to an invasive plant species that poses a threat to the region’s indigenous flora and overall biodiversity. Let’s delve into what makes the ice plant, scientifically known as Carpobrotus edulis, both captivating and alarmingly invasive.

On initial observation, the ice plant seems perfectly at home on the scenic cliffs and dunes of the Bay Area. It boasts robust, succulent-like green leaves that contribute to its picturesque appearance. During the spring and summer months, its flowers, ranging in hues from vibrant yellows to deep purples, create a captivating tapestry that blankets extensive sections of the coastline.

The ice plant’s ability to rapidly absorb water and essential nutrients gives it a competitive advantage over native plant species, many of which have evolved to thrive in California’s more arid and drought-prone climates. This means that despite looking the part, it’s actually damaging to the climate. One way to defeat this plant is to report it to NOAA if you happen to see it.
