Ornamental Cherry Trees: All Beauty, No Bite
Ornamental cherry trees, including popular Japanese flowering varieties like Prunus serrulata, are prized for their stunning floral displays, not their fruit. These trees have been cultivated over centuries to prioritize large, vibrant, and long-lasting blossoms. While they might produce small, pea-sized cherries, these fruits are generally extremely sour, bitter, and unappetizing for human consumption. They serve as a food source for birds, who can process them without harm. For gardeners and homeowners, the choice of an ornamental variety focuses on aesthetic qualities like flower color (from pure white to deep pink), tree shape (weeping, columnar, or vase-shaped), and vibrant fall foliage, not a summer fruit harvest.
Identifying Ornamental Cherries
During the spring, ornamental cherries are easily distinguished by their profuse and often double-petaled flowers, which are far more intense than the simpler, single-petaled flowers of most fruiting varieties. In autumn, the difference becomes even clearer as many ornamental types produce stunning red and orange leaf colors, a trait uncommon in fruiting cherries. Additionally, at a nursery, the label will explicitly state if the tree is ornamental or a fruiting variety.
Fruiting Cherry Trees: The Edible Harvest
Fruiting cherry trees are cultivated specifically to produce delicious fruit for human consumption. The two primary species for this purpose are the sweet cherry (Prunus avium) and the sour cherry (Prunus cerasus). These trees typically have less spectacular, smaller, and often white or blush-pink blossoms compared to their ornamental cousins. Their energy is directed toward producing juicy, flavorful fruit rather than an intense floral show.
The Poisonous Pits, Leaves, and Stems
Regardless of whether a cherry tree is ornamental or fruiting, it is crucial to remember that the pits, leaves, and stems of almost all Prunus species contain cyanogenic glycosides, which release cyanide when metabolized. This makes them highly toxic if chewed or ingested in large quantities. While the fruit flesh itself is safe for humans, the pits can be particularly dangerous for pets, especially dogs, who may chew them and be at risk of cyanide poisoning or intestinal blockage. This danger extends to the wilted leaves of cherry trees, which can be highly toxic to livestock.
Can you eat wild cherries?
While many wild cherry varieties, such as the Black Cherry (Prunus serotina) and Chokecherry (Prunus virginiana), produce edible fruit, foraging requires absolute certainty. Confusing a wild cherry tree with a poisonous look-alike, such as moonseed berries or deadly nightshade, can be a serious mistake. For this reason, experts recommend buying cherries from a grocery store unless you are 100% certain of the tree's identification.
Comparison Table: Ornamental vs. Fruiting Cherry Trees
| Feature | Ornamental Cherry Trees | Fruiting Cherry Trees |
|---|---|---|
| Primary Purpose | Aesthetic display of flowers | Production of edible fruit |
| Flowers | Often large, double-petaled, and more profuse | Smaller, simpler, single-petaled blossoms |
| Fruit | Small, bitter, and largely inedible for humans | Large, juicy, and flavorful for eating |
| Harvest Focus | N/A (not grown for harvest) | Timely harvest of ripe fruit |
| Lifespan | Typically longer-lived (often 35+ years) | Generally shorter-lived (around 25 years) |
| Care Needs | Less demanding, adapted for beauty | More attention to climate, soil, pests |
| Fall Foliage | Often boasts brilliant red and orange colors | Usually less striking, mostly green leaves |
Safe Handling and Gardening Practices
To ensure safety for your household and pets, practice responsible gardening. Always positively identify a tree before attempting to eat any part of it. If you have a fruiting cherry tree, be meticulous in removing all pits when preparing fruit for consumption, especially around children and pets. Be mindful of fallen branches or leaves, as they also pose a toxicity risk. If you are ever in doubt about a plant's edibility, consult an expert rather than risking consumption. For those growing flowering varieties, enjoy the visual splendor, but remember the fruit is not for eating.
Conclusion
The simple answer to "Are there cherry trees that aren't edible?" is a definitive yes. Many trees within the Prunus genus, particularly ornamental cultivars, are not bred for fruit production and, as a result, have small, bitter, and unpalatable fruit. Furthermore, it's vital to remember that all cherry pits, stems, and leaves contain toxic compounds and should never be consumed. Proper identification of the tree variety and safe handling of the fruit are essential for the health and safety of both people and pets.
