What can you plant under a California oak that requires no summer water and can handle both the shade of the canopy and the regular leaf drop? Some California Native plants thrive under the shade of oaks, including Coffeeberry (Rhamnus californica, shown above) and many native ferns, especially Sword Fern (Polystichum munitum) and Giant Chain Fern (Woodwardia fimbriata). In areas that fall under the dripline but get more sun, some Manzanita (Arctostaphylos), Sage species (Salvias,) Tiarella, Heuchera, and many native grasses shine. Bulbs are another option that survive on Spring rainfall alone. Cyclamen, Muscari, and some narcissus can put on exquisite early spring shows. Got a go-to plant that thrives under oaks?
