The Solanum catalog focuses on the lesser-known edible “solanaberries” — a fascinating group of nightshade fruits closely-related to Tomatoes & Eggplants. Featuring Naranjilla, Tamarillo, Pepino, Cocona, Australian Bush Tomatoes, and many other wild and cultivated relatives, this collection showcases unusual flavors ranging from bright and acidic to earthy and tomato-like. These species offer exciting potential for adventurous gardeners and cooks.

Flavors range from sweet-tart and aromatic to tangy or subtly tomato-like. Many species are enjoyed fresh when fully ripe, while others shine in cooked preparations such as sauces, jams, jellies, pies, chutneys, or juices. Naranjilla and Tamarillo add bright acidity to beverages and desserts, Pepino offers a mild melon-like sweetness for fresh eating or salads, and Australian Bush Tomatoes provide an intense, earthy flavor often used dried or as a spice. Garden Huckleberry and Wonderberry are traditionally cooked into preserves or pies. As with many nightshades, only fully ripe fruits should be consumed; unripe berries and foliage often contain higher levels of alkaloids and should be avoided.

Solanum berries and related species in the collection are nutrient-rich, typically providing good amounts of vitamin C, antioxidants (including carotenoids and polyphenols), dietary fiber, and various B vitamins. Some species also contribute potassium, vitamin A precursors, and other phytonutrients that may support immune function and offer anti-inflammatory benefits. Nutrient profiles vary across the diverse types—tamarillo and naranjilla tend to be notably high in vitamin C and acidity, while others emphasize different balances of sugars and bioactive compounds. Overall, these fruits add valuable micronutrients and phytochemical diversity to the diet beyond more common nightshade crops.

The Solanum genus is enormous and cosmopolitan, with many edible species originating in the tropical and subtropical regions of the Americas, Africa, Australia, and Asia. The collection highlights species adapted to varied environments: Australian bush tomatoes from arid or semi-arid zones, highland types like naranjilla from Andean cloud forests, and others from humid tropical lowlands or disturbed habitats. Most thrive in warm conditions with full sun to partial shade and well-drained soil, performing as tender perennials or annuals depending on climate and species. Many are opportunistic plants that colonize forest edges, clearings, or cultivated areas.

Like other members of the Solanaceae family, these Solanum species can be affected by common issues such as early and late blight, anthracnose, leaf spot fungi, powdery mildew, viral diseases, aphids, whiteflies, flea beetles, and spider mites. Root rots may occur in overly wet soils. Many of the wild or less-domesticated species in the collection tend to show greater natural resilience or tolerance to certain pests and diseases compared to intensively bred commercial solanaceous crops. Good cultural practices—including proper spacing for airflow, crop rotation where possible, sanitation, and regular monitoring—help minimize problems in a diverse planting.

The Solanum genus exhibits varying degrees of cross-compatibility among species, which has historically allowed for natural hybridization and offers potential for intentional breeding. The broad collection of bush tomatoes, tree tomatoes, naranjilla relatives, and other edible types provides valuable genetic diversity for selecting or creating improved cultivars with enhanced flavor, larger fruit size, better disease resistance, or greater environmental adaptability. Wild and semi-wild relatives can serve as sources of useful traits, though breeders must account for differences in ploidy levels and potential crossing barriers common in this large and complex genus.
