Pacific coralroot is a unique native orchid that grows without green leaves, appearing as reddish-brown stems with small coral-colored flowers. This fascinating parasitic plant obtains nutrients through underground fungal partnerships rather than photosynthesis. It emerges unpredictably in summer, creating delicate spikes in shaded woodland areas.
In an HOA neighborhood
Pacific Coralroot takes more care to keep looking intentional in a front yard. Maintenance level: low. Consider it for backyard or mid-zone beds rather than the street edge.
Works well in: backyard only.
- Appears leafless and can look like dead stems
