From the towering chaparral yucca (Hesperoyucca whipplei) to the miniscule California plantain (Plantago erecta), the Irvine Ranch Natural Landmarks is home to a large number of unique and sometimes rare native plants. Native Plant Week, which is April 16-24, celebrates these species that support a diverse collection of local wildlife.
Not surprisingly, the Landmarks contain a wide variety of plant communities, including coastal sage scrub, chaparral, valley grassland, oak woodland and riparian forest – all home to many native plants. Native plants are species that are indigenous to a certain area, and have not been introduced by human activity. In the Landmarks, some of the most common native plants include California sagebrush (Artemisia californica), coast live oak (Quercus agrifolia), laurel sumac (Malosma laurina), and purple needle grass (Stipa pulchra).
