In Roald Dahl’s enchanting novel, James and the Giant Peach, a magical crystal causes a dead peach tree to sprout colossal, juicy peaches. It’s a whimsical thought: what if we could cultivate giant fruits without the hassle of pests or dubious old ladies?
Fast forward to the mid-2030s, where botanists have cracked the code. Scientists have enhanced the classic James peach, harnessing genetics to yield extra-large fruits and vegetables, ultimately creating crops that produce an array of delectable and nutritious foods.
One notable innovation is the fruit salad tree, a marvel developed in the early 2020s. Utilizing ancient grafting techniques, hybrid plants are born by combining branches from different species, allowing trees to bear multiple types of fruit. For instance, a grafted tree can yield both red and golden delicious apples, along with other varieties. In 2013, an innovative horticulturist successfully grafted a tree to produce 250 different types of apples. Citrus hybrids combine lemons, limes, oranges, and grapefruits, while other variations produce plums, peaches, nectarines, and apricots.
A remarkable example is the Tomtato, which merges potato roots with tomato foliage. These hybrids arise from closely related plants, such as tomatoes and potatoes, which both belong to the same genus. Additionally, the eggplant also falls under the same classification, showcasing the ease with which thriving hybrids can be created.
By the early 2030s, advanced gene editing and selective breeding will make it feasible to grow fruits from entirely different botanical families. This opens the door to extraordinary plants that can produce bananas, citrus, apples, and peaches from a single tree, tailored to farmers’ and consumers’ preferences.
Gardeners have also turned to Brassica oleracea, a species that generates various types of cabbage, kale, broccoli, cauliflower, and Brussels sprouts. Hybridization was simple, enabling the development of plants yielding these vegetables in diverse areas of a large garden.

While grafting yielded impressive results, it was labor-intensive and costly since each plant required individual attention. The game-changer came in the mid-2030s, with plant geneticists succeeding in creating hybrid superplants from seeds, allowing broader access to multiple harvests from a single crop.
Organizations like PolyPlants are leading the way in novel agricultural practices. As public perception towards gene editing becomes more favorable, people recognize the nutritional benefits. For instance, fruits engineered to be rich in vitamins and nutrients are being developed. A 2022 study focused on creating tomatoes packed with antioxidant-rich anthocyanins, linked to longevity benefits. Other modifications through gene editing have led to polyplants that exhibit enhanced resistance to fungal pathogens, salinity, drought, and insect infestations. By engineering the root microbiome, mycorrhizal fungi are tailored for each crop component, stimulating growth and productivity.
As climate change escalates and traditional crops face threats, large-scale gene editing holds immense importance. PolyPlant’s innovations aim to ensure global food security amidst rising temperatures.
Genomic studies have pinpointed a cluster of genes linked to the size of edible plant components. Grafting techniques enable gene editing in species not directly modified, such as avocados, coffee, and cocoa. These advancements have facilitated the creation of plants that produce oversized fruits.
Honoring Roald Dahl’s legacy, scientists have developed a peach variety that bears fruit as large as a suitcase. A festive tradition has emerged around this giant fruit tree, celebrating the harvest with events encouraging children to enjoy these delightful oversized peaches, cherries, and strawberries.
The crops and trees yielding colossal, nutritious food are not solely for feasting; they play a vital role in addressing nutrition deficits in regions grappling with food insecurity.
