California native plants that grow in full shade
What we are calling full shade is shade under a dense canopy of evergreen trees, not under a deck or other solid structure. Some light must penetrate in order for the plants to photosynthesize.
Don't forget that our full shade may not be like your full shade. Most people can give a little more sun to many of these plants. Look on each individual plant's description (the links) to get more precise information about each plant's needs or to order it.
Wild Ginger is a really neat little perennial with heart-shaped leaves that likes full shade. Wild ginger smells spicy in a nice way. The flower is the best thing about this plant. There are three petals (sepals) with 1 to 2 inch, spur-like projections. The inside is white with a red center. The flowers are about 0.5 to 1 inch wide. This creeping perennial is native in the redwood forest and yellow pine forest so it may need a little moisture in other areas.
Think about that north wall that is really moist and shady. Think about that shady parking garage planting bed that someone designed.
