Oxalis oregana, known commonly as Redwood Sorrel or Oregon Oxalis, is a native groundcover that thrives in part to full shade and produces beautiful white flowers. It is superficially similar to clover in appearance but is unrelated. It is best suited for contained areas or locations with room to spread, as it can aggressively grow from rhizomes. The stems contain oxalic acid, giving it a similar flavor to rhubarb when chewed, but be mindful as oxalic acid is toxic in large quantities. For best performance, summer irrigation is recommended to prevent dormancy, however it will persist without irrigation.
