Although sometimes listed as extending to New Brunswick, the species is not known from collections there, and does not appear in the most authoritative works on the flora of that Canadian province. The species is endangered in Maine, where it is in serious decline due to commercial development of its beach habitats. |

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] | 20 inches (51 cm) | | Seed Spread Rate [1] | Slow | | Seed Vigor [1] | Low | | Seeds Per [1] | 2500 / lb (5512 / kg) | | Shape/Orientation [1] | Rounded | | Structure [2] | Shrub | | Usage [2] | A green dye can be obtained from the leaves;
