It grows in forests, most often at low elevation near the coast, but it is also in the Sierra Nevada and Cascades; it grows at altitudes of 100–1,900 m. P. subcordata var. subcordata, Klamath plum, is also found in Washington. |

This toxin is found mainly in the leaves and seed and is readily detected by its bitter taste. It is usually present in too small a quantity to do any harm but any very bitter seed or fruit should not be eaten. In small quantities, hydrogen cyanide has been shown to stimulate respiration and improve digestion, it is also claimed to be of benefit in the treatment of cancer. In excess, however, it can cause respiratory failure and even death. | | Leaf Type [2] | Deciduous | | Lifespan [1] | Perennial | | Pollinators [2] | Insects, Lepidoptera | | Propagation [1] | Bare Root, Container, Cutting, Seed | | Root Depth [1] | 12 inches (30 cm) | | Seed Spread Rate [1] | Moderate | | Seed Vigor [1] | High | | Seeds Per [1] | 556 / lb (1226 / kg) | | Shape/Orientation [1] | Erect | | Structure [2] | Tree | | Usage [2] | A green dye can be obtained from the leaves;
