The Malus domestica species encompasses most cultivated apples, distinguished from crabapples by their larger fruit (greater than 2 inches in diameter). Ambrosia is a cultivar of Malus domestica, discovered as a chance seedling, likely a natural cross between varieties such as Golden Delicious and Jonagold or Starking Delicious, though its exact parentage is unconfirmed. Ambrosia’s genetics contribute to its sweet flavor and slow-browning flesh, making it a standout in modern apple breeding.
History of the Ambrosia Apple
The Ambrosia Apple was discovered in the early 1990s by Wilfrid and Sally Mennell in their orchard in Cawston, British Columbia, Canada, located in the Similkameen Valley. The couple found a unique seedling tree growing among their Jonagold plantings, producing apples with exceptional sweetness, crispness, and an attractive red-and-yellow coloration. Recognizing its potential, they propagated the tree and named the variety Ambrosia, evoking the mythical nectar of the gods due to its delightful flavor.
The Mennells patented Ambrosia in 1993 and worked with the British Columbia Fruit Growers’ Association and the Okanagan Plant Improvement Corporation (PICO) to commercialize it. By the late 1990s, Ambrosia was introduced to North American markets, gaining rapid popularity in Canada and the United States, particularly in Washington State, which became a major producer. Its success spread to Europe, Australia, New Zealand, Chile, and South Africa, where licensed growers cultivate it under controlled conditions to maintain quality.
Today, Ambrosia is a premium apple variety, with significant production in British Columbia, Washington, and Chile. Its rise is attributed to its sweet, low-acid flavor, slow-browning flesh, and aggressive marketing as a family-friendly apple. Ambrosia’s controlled cultivation ensures consistent quality, making it a favorite in grocery stores, farmers’ markets, and school lunch programs.
Native Area
As a cultivated variety, the Ambrosia Apple does not have a true native range but is derived from Malus domestica, which traces its origins to Central Asia, particularly Kazakhstan, where the wild apple species Malus sieversii is considered the primary ancestor of modern apples. Malus domestica was domesticated thousands of years ago and spread across Europe and Asia via trade routes like the Silk Road. European colonists introduced apple cultivation to North America in the 17th century, setting the stage for Ambrosia’s discovery.
The Ambrosia Apple was first identified in Cawston, British Columbia, Canada, in the Similkameen Valley, a region known for its warm days, cool nights, and fertile soils, ideal for apple production. It thrives in temperate climates and is grown in:
- Canada: British Columbia (Okanagan and Similkameen Valleys)
- United States: Washington (a major producer), New York, Michigan
- South America: Chile, Argentina
- Oceania: Australia, New Zealand
- Europe: France, Italy, United Kingdom
- Africa: South Africa
Ambrosia’s adaptability to both cool and warm temperate climates, combined with its moderate chilling requirements, has made it a global crop, particularly in regions with long growing seasons.
Identifying Characteristics
- Size and Shape: Ambrosia apples are medium to large, typically 2.5–3.5 inches in diameter, with a round to slightly conical shape. They have a smooth, symmetrical appearance with a broad base and a slightly tapered top.
- Skin: The skin is thin, glossy, and smooth, featuring a bright red to pink blush over a creamy yellow background. The red coloration covers 50–70% of the surface, with faint yellow striping and small, white lenticels (pores) scattered across. The skin is tender, making it easy to bite into but slightly prone to bruising.
- Flesh: The flesh is creamy white, crisp, and juicy, with a fine-grained texture that is dense yet tender, similar to Golden Delicious but crisper. Its slow-browning property when cut is a hallmark trait, ideal for fresh preparations.
- Core and Seeds: The core is small to medium, with dark brown to black seeds encased in a fibrous center. The seed cavities are compact, maximizing edible flesh.
- Stem: The stem is medium-length, slender, and greenish-brown, set in a deep, narrow cavity with minimal russeting.
- Aroma: Ambrosia apples have a sweet, floral aroma with notes of honey, pear, and vanilla, detectable when cut or bitten.
- Tree Characteristics: Ambrosia apple trees are medium-sized, reaching 10–20 feet on dwarf or semi-dwarf rootstocks, with a spreading, upright canopy. The trees are moderately vigorous, with dark green, ovate leaves and white to pink flowers in spring. They are moderately susceptible to pests and diseases, requiring careful management.
Taste
- Sweetness: Ambrosia has high sweetness, with a honeyed, sugary quality likely inherited from Golden Delicious, making it one of the sweetest modern apple varieties.
- Tartness: The low acidity results in minimal tartness, giving it a smooth, nectar-like profile that appeals to children and those who prefer sweeter apples.
- Flavor Notes: The flavor is rich and aromatic, with notes of honey, pear, vanilla, and a subtle floral or caramel undertone, often described as “dessert-like” or “nectarous.”

Care and Cultivation Tips for Ambrosia Apple Trees
- Planting: Plant in early spring in a sunny, well-drained site with loamy soil (pH 6.0–7.0). Choose dwarf or semi-dwarf rootstocks (e.g., M.9, M.26) for manageable size and earlier fruiting. Dig a hole twice as wide and as deep as the root ball, plant with the graft union 2 inches above ground, and water thoroughly. Space trees 10–20 feet apart, depending on rootstock.
- Watering: Water deeply (1–2 inches per week) during the first year to establish roots. Once established, water during dry spells, especially during fruit development (June–September). Avoid waterlogged soil to prevent root rot.
- Pruning: Prune in late winter or early spring while dormant to remove dead, diseased, or crossing branches and maintain an open canopy. Thin fruit in early summer to improve size and prevent overbearing.
- Fertilization: Apply a balanced fertilizer (e.g., 10-10-10) in early spring, providing 0.5 pounds per year of tree age (up to 5 pounds). Conduct a soil test to adjust nutrients. Avoid over-fertilizing to prevent excessive vegetative growth.
- Pest and Disease Control: Ambrosia is moderately susceptible to apple scab, fire blight, powdery mildew, and pests like codling moths, apple maggots, and aphids. Use integrated pest management (IPM), including resistant rootstocks, regular monitoring, and targeted sprays (e.g., sulfur for scab, Bt for moths). Clean up fallen leaves and fruit to reduce disease pressure.
- Pollination: Plant a compatible pollinator (e.g., Gala, Fuji, or a crabapple like Evereste) within 50–100 feet to ensure fruit set.
- Winter Protection: In Zone 4, mulch around the base (4–6 inches, keeping away from the trunk) to insulate roots. Wrap young trees with burlap to protect against winter sunscald and rodent damage.
Challenges and Considerations
- Low Acidity: Ambrosia’s minimal tartness may be too sweet for those who prefer a balanced sweet-tart profile, limiting its appeal in some recipes.
- Disease Susceptibility: The cultivar is prone to apple scab and fire blight, particularly in humid climates, requiring proactive management.
- Bruising: The tender skin is prone to bruising, requiring careful handling during harvest and transport.
- Pollination Needs: Self-sterile trees require a nearby pollinator, which may limit fruit production in isolated settings.
- Limited Availability: Ambrosia’s controlled cultivation means it may be less widely available than mass-produced varieties like Fuji, particularly outside peak seasons.
