A tree is never simply “beautiful” or “suitable”. A species may be exceptional in one setting and a liability in another. A tree that thrives in a sheltered courtyard may fail in a hot, windy street. A coastal evergreen may anchor a garden with quiet permanence. A flowering tree may define a civic space. A sculptural aloe tree, underused indigenous specimen, or carefully chosen exotic may be unforgettable, but only where scale, climate and setting allow it.

Arbeau is being built to make those distinctions visible.

At launch, users will be able to explore trees by climate fit, landscape use, design character and practical constraints, including street-tree suitability, courtyard scale, estate avenues, parks, coastal planting, dry gardens, shade, screening, landmark specimens, root space, paving risk, wind exposure, irrigation needs, fruit or pod drop, thorniness and long-term maintenance burden.

Arbeau is grounded in Southern African landscape knowledge, but it is not constrained by simplistic labels. Indigenous species matter deeply. So does ecological context. But cities are anthropogenic habitats, and resilient urban forests need diversity, performance, spatial intelligence and climate compatibility. Selective exotics, when responsibly chosen, can help create cooler, more liveable and more distinctive places.

The Arbeau render library is also being developed as a visual field guide: isolated, high-resolution tree portraits that show form, canopy density, foliage texture, trunk character, seasonal change, flowers and fruit. These are not decorative placeholders. They are intended to help designers, homeowners, municipalities, estates and developers see the tree before it is specified, planted and lived with.

Arbeau begins with a simple premise: better trees make better places, especially when chosen with intelligence.
