A Tree of 40 Fruit is one of a series of fruit trees created by the Syracuse University Professor Sam Van Aken using the technique of grafting.[1] Each tree produces forty types of stone fruit, of the genus Prunus, ripening sequentially from July to October in the United States.[2][3]

Development

[edit]

Sam Van Aken is an associate professor of sculpture at Syracuse University.[4] He is a contemporary artist who works beyond traditional art making and develops new perspective art projects in communication, botany, and agriculture.[5] Aken was a 2018 Artist-in-Residence at the McColl Center for Art + Innovation in Charlotte, NC.[6]

His family is Pennsylvania Dutch, and he grew up on the family farm.[4]

In 2008, while looking for specimens to create a multicolored blossom tree as an art project, Van Aken acquired the 3-acre (1.2 ha) orchard of the New York State Agricultural Experiment Station, which was closing due to funding cuts.[2][3] He began to graft buds from some of the over 250 heritage varieties grown there, some unique, onto a stock tree.[3] Over the course of about five years the tree accumulated branches from forty different "donor" trees, each with a different fruit, including almond, apricot, cherry, nectarine, peach and plum varieties.[3]

Each spring the tree's blossom is a mix of different shades of red, pink and white.[3]

The tree of 40 fruits was originally conceived as an art project, and Sam Van Aken hoped that people would notice that the tree has different kinds of flower in spring and has different types of fruit in summer. However, the project also introduces the changes in agricultural practices over the centuries.[7]

Distribution

The Tree of 40 Fruit is a single grafted tree capable of producing up to forty different varieties of stone , including peaches, , apricots, nectarines, cherries, and almonds, which ripen sequentially from spring blossoms to summer harvest. Created by art professor and sculptor Sam Van Aken starting in 2008, the project began when he acquired an orchard of 300-year-old, endangered fruit trees at a auction in , rescuing over 250 varieties from destruction. The trees are produced using chip grafting, where buds or branches from diverse stone fruit varieties are meticulously attached to a mature host tree—typically a tree—over a five-year period, allowing the grafts to integrate and mature before fruiting begins around year nine. Van Aken's work emphasizes conservation, as many of the incorporated varieties are antique or types no longer grown commercially due to their unappealing appearance or short , yet they offer unique flavors ranging from sweet to sour. The trees bloom vibrantly in , and in spring, creating a visually striking display that evolves into a patchwork of colorful fruits by summer. As living artworks, dozens of Trees of 40 Fruit have been installed worldwide as of 2025, including public sites like the Everson Museum of Art in Syracuse, the 21c Museum Hotel in , and 2025 additions at in and Planting Fields Arboretum in . These installations not only function as edible sculptures but also promote community engagement through urban orchards and educational programs on and .

History and Development

Origins and Inspiration

Sam Van Aken, an artist and associate professor in the School of Art at , has long explored the intersections of art, , and public space in his work. Raised on a in , Van Aken's practice prior to the Tree of 40 Fruit project included installations that engaged with natural elements and community narratives, laying the groundwork for his later fusion of artistic expression with agricultural preservation. In 2008, Van Aken learned of an impending closure at the New York State Agricultural Experiment Station in Geneva, New York, where a 3-acre orchard housing over 250 varieties of heirloom stone fruits—such as peaches, plums, apricots, nectarines, cherries, and almonds—was slated for demolition due to lack of funding. Many of these varieties, developed over generations for unique flavors and regional adaptations, faced extinction amid commercial agriculture's shift toward monoculture production for uniformity and yield efficiency. To avert their loss, Van Aken leased the orchard using grants from Syracuse University and Creative Capital, gaining access to this irreplaceable collection that represented a fading chapter of New York's agricultural heritage. The orchard's profoundly inspired Van Aken, prompting him to envision a single tree that could encapsulate the multiplicity of these fruits, their historical significance, and the cultural stories embedded in their cultivation and consumption across immigrant communities and local traditions. Each variety carried narratives of migration, , and , from 19th-century breeding experiments to family orchards displaced by industrialization. Between 2008 and 2010, Van Aken initiated experiments multiple varieties onto individual trees, motivated by a desire to preserve this diversity while transforming it into a living artwork that evokes themes of ecological and cultural continuity.

Creation Process

The creation of the Tree of 40 Fruit began in 2008 with small-scale experiments by Sam Van Aken, who initially worked with a limited number of stone fruit varieties to test compatibility on trees. By 2011, the first multi-variety tree was achieved at , marking a significant milestone as it integrated multiple stone fruits onto a single specimen and was dedicated during a campus remembrance event. The development process is iterative and time-intensive, typically spanning 5 to 9 years per tree to reach full maturity and fruiting potential. Van Aken sources scion wood—small branches or buds—from and antique stone fruit trees, often from a 19th-century orchard in that he leased to access over 250 rare varieties, including peaches, plums, apricots, nectarines, cherries, and almonds. Compatibility testing is essential, as all grafts are limited to species to ensure vascular integration, with initial grafts performed on young trees pruned into an open-centered vase shape featuring 4 to 5 main branches. Key challenges include achieving successful graft unions, where the scion must integrate with the host's vascular system; success rates for stone fruit grafts vary depending on the method and conditions. Balancing branch loads is critical to prevent vigorous varieties from dominating weaker ones, requiring ongoing to maintain equilibrium and promote even growth across the diverse grafts. Van Aken collaborates with horticulturists to refine techniques tailored to species, primarily employing chip budding—inserting a sliver into a host incision—and cleft , where a scion is wedged into a split branch, both secured with tape or wraps to heal over winter. Trees are typically planted with 15 to 20 varieties already established, followed by annual visits for additional grafts and maintenance over several years. A notable occurred in 2014 when Van Aken presented the project's progress at TEDxManhattan, emphasizing its artistic and philosophical dimensions as a means to preserve endangered varieties and evoke abundance in urban environments.

Botanical Characteristics

Grafting Technique

is a horticultural technique that involves joining the tissues of two —a scion, which is the upper portion bearing the desired variety, and a , the lower portion providing the root —so that they grow together as a single organism. This union is achieved by precisely aligning the layers of both parts, allowing for the exchange of nutrients, water, and hormones through the reformed vascular tissues. For the Tree of 40 Fruit, artist Sam Van Aken employs specific methods to incorporate multiple stone fruit varieties onto a single . Chip budding is used for smaller branches, where a single bud from the scion is inserted into a small incision on the , while cleft is applied to larger branches by splitting the stock and wedging in the scion. These techniques are applied sequentially over a period of three to five years, gradually building up the tree's structure by adding grafts to developing branches each season. Successful grafting requires compatibility between the scion and rootstock, which in this case is facilitated by selecting all varieties from the genus, encompassing stone fruits such as peaches, plums, apricots, nectarines, cherries, and almonds. Although all varieties are from the genus, interstock varieties such as Santa Rosa plum are often used to bridge compatibility issues between less compatible scions and the rootstock. The rootstock is typically a hardy plum variety like (), chosen for its broad compatibility with other species and resistance to diseases like . The biological process begins with the formation of tissue—a mass of undifferentiated cells—at the graft site, typically occurring within two to four weeks after joining, which bridges the scion and . This is followed by vascular integration, where new and tissues develop to connect the two parts permanently. Key success factors include performing grafts during late winter , when the plants are inactive and less prone to sap loss, and providing aftercare such as wrapping the union with tape or wax to prevent and to direct growth. Despite these methods, limitations exist; not all grafts achieve long-term due to potential incompatibility issues or environmental stresses, necessitating annual to balance branch growth, remove failed unions, and prevent the tree from overbearing, which could weaken the overall structure.

Growth and Fruiting Cycle

The maturation of the Tree of 40 Fruit typically spans about 9 years from the initial to achieving full production capacity, with the grafting process requiring about 5 years for the 40 varieties to fully establish and an additional 4 years before substantial fruiting begins. The seasonal cycle begins in spring with a striking display of blossoming, where the produces waves of , , and flowers as the various stone fruit varieties bloom at slightly staggered times, creating a multicolored effect across the canopy. This is followed by fruit set in , with occurring sequentially from July through October in the , allowing for an extended period of development without overwhelming the tree's resources. The tree's structure supports this cycle through a multi-trunk scaffold design, typically featuring 4 to 5 primary vase-shaped branches with over 40 graft sites strategically distributed to minimize competition for light, water, and nutrients; mature trees reach an average height of 15 to 20 feet and require annual to maintain balance, promote airflow, and encourage even growth. Environmental requirements include full sun exposure for at least 6 to 8 hours daily and well-drained, fertile soil to prevent root rot, with the tree suited to USDA hardiness zones 5 to 9 depending on the selected varieties. Many of the grafted stone fruit varieties are self-incompatible, necessitating cross-pollination from nearby compatible trees or pollinators such as bees to ensure reliable fruit set. Harvest dynamics feature staggered ripening in waves, such as early-season cherries in , mid-season peaches and nectarines in to September, and late plums into October, enabling a prolonged period of several months rather than a single burst. Once mature, a single tree yields approximately 100 to 200 fruits annually, with peak production delivering around 20 fruits per week over 10 to 12 weeks, though this varies based on care, climate, and practices.

Varieties and Fruits

Stone Fruit Varieties

The Tree of 40 Fruit incorporates approximately 40 heirloom varieties from the genus, all belonging to the category of stone fruits distinguished by their single large pit enclosing the seed. These varieties encompass peaches, plums, apricots, nectarines, cherries, and almonds, with the composition typically including multiple examples from each type to achieve diversity on a single tree. The selection of these varieties emphasizes heirloom and antique types originating from the Northeast , particularly those preserved from a historic orchard at the New York State Agricultural Experiment Station in , which faced demolition in 2008. Criteria for inclusion focus on regional heritage, ensuring representation of fruits adapted to local climates, as well as diversity in flavor profiles—ranging from sweet and juicy to tart and firm—and fruit textures, such as freestone (where the flesh separates easily from the pit) versus (where the flesh adheres tightly). Varieties are also chosen for their staggered ripening times, allowing for an extended harvest period across summer months, though detailed biological cycles are covered elsewhere. Unique traits among these stone fruits highlight their endangered status and specialized adaptations; for instance, many were non-commercially viable heirlooms at risk of extinction, now conserved through , with some peaches noted for late-season reliability to extend productivity in variable Northeast weather. Plums exhibit a broad spectrum, from deep purple-skinned, juicy varieties ideal for fresh eating to yellow-fleshed types suited for due to their balanced sweetness and slight tartness. Peaches and nectarines contribute aromatic, fuzzy or smooth-skinned fruits with creamy or flesh, offering contrasts in ripeness from firmness to late-season succulence, while apricots provide compact, golden orbs with tangy acidity for preserves. Cherries add vibrant red or black fruits with pit-enclosed tartness, enhancing early-season yields, and almonds supply nuts from select branches, rounding out the tree's pit-bearing diversity. Overall, these profiles support versatile uses, from raw consumption to culinary applications, underscoring the project's role in preserving flavor complexity lost to modern .

Variants and Adaptations

One notable variant of the Tree of 40 Fruit concept is the "Tree of 40 Fruit: New York Apples," introduced by artist Sam Van Aken circa 2018, which grafts 40 heirloom varieties of the apple species Malus domestica onto a single tree. This adaptation focuses on New York-specific heirlooms, such as Northern Spy—originated in East Bloomfield, New York, in the early —and Roxbury Russet, one of North America's oldest cultivars, to suit the Northeast's cooler and shorter growing season. These trees preserve regional by reviving varieties once common in the area's historic orchards but now rare due to commercial farming shifts. Technical adjustments for the apple variant include the use of dwarfing rootstocks, which promote smaller tree size for easier management in urban or garden settings while maintaining productivity. The grafting process mirrors the original stone fruit model but leverages the high compatibility within the Malus genus, typically requiring about five years to fully establish the multi-variety canopy. Whip grafting techniques are employed, where scions from dormant branches are joined to the host tree in spring and secured until union forms, ensuring reliable fruiting within 1.5 years per graft. Beyond apples, Van Aken has developed experimental adaptations incorporating pears (Pyrus species) and hybrid fruit combinations, as seen in the Open Orchard project, where individual trees bear multiple pear varieties alongside apples and stone fruits. These site-specific editions tailor the concept to local heirlooms, such as regional peaches in warmer climates, by selecting compatible scions that thrive in diverse environments. The overarching purpose of these variants is to broaden fruit preservation efforts to pome fruits and beyond, sustaining cultural and through the signature aesthetic of a single tree yielding an array of blossoms and harvests.

Artistic and Cultural Significance

As a Living Sculpture

The Tree of 40 Fruit, created by artist Sam Van Aken, functions as a living sculpture that integrates , , and into a single organic form, preserving heirloom stone fruit varieties while challenging conventional notions of monumental art. Van Aken conceptualizes each tree as a dynamic installation that embodies abundance and historical continuity, drawing on to fuse diverse species into a unified entity that evolves seasonally. This approach transforms the tree from a mere botanical specimen into an edible artwork, emphasizing participatory interaction with nature over static viewing. Visually, the tree captivates through its temporal transformations: in spring, it erupts in a vibrant array of blossoms ranging from to white and crimson, creating a multicolored canopy that shifts like a living over weeks as different varieties bloom sequentially. By summer, the branches bear a of over 40 stone fruits—including peaches, plums, apricots, nectarines, cherries, and almonds—symbolizing diversity and plenitude in a single, harmonious structure. This aesthetic progression not only highlights the tree's sculptural qualities but also underscores its role in evoking wonder and reflection on ecological interconnectedness. As an artistic installation, the Tree of 40 Fruit has been exhibited in museum settings, such as editions at the Eli and Edythe Broad Art Museum at and the Everson Museum of Art, where it is presented as a numbered, site-specific inviting public interaction. These displays often include events that encourage visitors to engage directly with the ripening fruits, fostering a sense of communal stewardship and sensory appreciation. The multi-fruit form is achieved through meticulous techniques that layer varieties onto a single . The project's artistic evolution traces back to its inaugural planting at in 2011, marking the beginning of an ongoing series that adapts to diverse environments while maintaining its core aesthetic and conceptual integrity. By 2020, at least 87 unique editions had been realized, each customized to local contexts, and the initiative continued to proliferate, reaching over 100 installations across public and institutional sites by 2025. This expansion reflects Van Aken's commitment to scalable, enduring that evolves with its surroundings, ensuring the sculpture's legacy as a blend of beauty, utility, and cultural commentary.

Role in Biodiversity Preservation

The Tree of 40 Fruit project, initiated by artist Sam Van Aken, has preserved over 200 at-risk stone fruit varieties by sourcing them from endangered orchards and integrating them into grafted trees, thereby preventing their in the face of commercial agricultural pressures. Each resulting tree functions as a compact genetic , housing up to 40 distinct varieties of peaches, plums, apricots, nectarines, cherries, and almonds that would otherwise be lost to history. This preservation is achieved through clonal propagation via , allowing the varieties to be replicated and distributed without relying on seed-based reproduction, which ensures genetic fidelity across generations. In a broader context, the project responds to the alarming decline of approximately 75% of global plant since 1900, largely attributable to industrialization and the widespread adoption of farming practices that prioritize high-yield, uniform crops over diverse heirlooms. By cultivating polycultures on individual trees, the initiative demonstrates an alternative to monocrops, enhancing resilience against pests, diseases, and climate variability while maintaining a spectrum of flavors, textures, and nutritional profiles inherent to traditional varieties. This approach underscores the value of in , countering the homogenization that has rendered many regional fruits obsolete. Public installations of these trees play a vital educational , sparking conversations about food heritage and agricultural diversity as communities interact with the blooming and fruiting cycles that reveal hidden stories embedded in the varieties. For instance, many fruits carry names tied to immigrant histories and regional traditions, serving as tangible links to cultural narratives and prompting reflection on how intersects with and identity. Through accessible displays in urban and institutional settings, the project cultivates public awareness of the need to safeguard for future generations. Scientifically, the Tree of 40 Fruit contributes to horticultural research via collaborations with institutions like the and the USDA, where trees are studied for long-term viability, efficacy, and adaptability in diverse environments. These partnerships facilitate archival and experimental , positioning the multi-variety trees as practical models for sustainable practices that integrate art, conservation, and ecology to bolster resilience.

Notable examples include installations at in , commissioned in 2019 near the Rodin Sculpture Garden. Community gardens in have also received trees through initiatives like the Open Orchard project on , which distributed grafted fruit trees to urban green spaces across the five boroughs starting in 2022. Host institutions manage the trees with ongoing care, including annual to promote balanced growth and support the diverse grafts, ensuring long-term viability in varying climates. Many sites organize public harvest events during the summer fruiting season, inviting visitors to collect and sample the array of stone fruits, which fosters and on .

Global Reach and Recent Plantings

The Tree of 40 Fruit project has expanded beyond the , with installations in , contributing to numerous trees worldwide by 2025. In , a notable example is the tree planted in Toronto's around 2017, showcasing the adaptability of the technique to northern climates. These international efforts highlight the project's role in conservation, preserving varieties through artistic dissemination. Recent U.S. plantings as of 2025 have focused on arboretums and educational institutions, building on the project's domestic foundation. In September 2025, a new tree debuted at the Planting Fields Arboretum in , New York, as part of the Catalyst 2025 initiative, emphasizing public access to multi-variety fruiting. Expansions at the Tyler School of Art in occurred earlier in 2025, integrating the trees into campus landscapes for educational purposes. Additionally, community distributions on in New York in 2024 supported urban orchard initiatives inspired by the project, promoting local fruit diversity. The expansion strategy involves collaborations with , museums, and non-governmental organizations to develop climate-adapted versions of the trees, prioritizing urban greening and in diverse environments. These partnerships facilitate the of rare stone fruit varieties, ensuring their survival amid modern agricultural pressures. Looking ahead, plans call for ongoing plantings, including apple variants tailored for Midwest states to broaden the project's scope beyond stone fruits. This ongoing dissemination aligns with broader goals of preservation by distributing resilient, multi-variety specimens to regional partners.
