Allergen Potential [1] | Medium-Low | | Edible [2] | May be edible.

Hydrogen cyanide is the substance that gives almonds their characteristic taste but it should only be consumed in very small quantities. Apple seeds do not normally contain very high quantities of hydrogen cyanide but, even so, should not be consumed in very large quantities. 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 [3] | Perennial | Pollinators [2] | Insects, Lepidoptera | Structure [2] | Tree | | Height [2] | 26 feet (8 m) | View Plants For A Future Record : Malus sieversii |
