The Po Basin mixed forests blanket the broad plain of the Po River across northern Italy, reaching from Turin eastward through regions such as Lombardy and Veneto to the Adriatic coast, and extending into Switzerland's Ticino canton, hemmed in by the Alps to the north and west and the Apennines to the south. Before intensive farming reshaped the lowlands, the natural cover was mixed deciduous oak forest of common oak (Quercus robur), Turkey oak (Quercus cerris), European hornbeam (Carpinus betulus), field elm, and South European flowering ash, alongside riparian woodlands of willow (Salix alba), alder (Alnus glutinosa), poplar, and ash, with holm oak (Quercus ilex) and wild olive nearer the coast. The climate is continental in the north and more Mediterranean toward the south, with annual rainfall ranging from about 500 to 1,000 mm. Now one of Europe's most industrialized and agricultural landscapes, the surviving wetlands remain vital for herons, egrets, and other waterbirds, holding Italy's only nesting site of the pygmy cormorant and supporting the globally threatened ferruginous duck and the critically endangered Adriatic sturgeon. For gardeners, the region's native woody flora includes ornamentally useful genera such as oak, hornbeam, ash, willow, and poplar.

About the temperate broadleaf & mixed forests biome

Four-season forests of deciduous hardwoods — oak, maple, beech — often mixed with conifers, shaped by warm summers and cold winters. Trees leaf out in spring and color in autumn; the generally fertile soils have made these forests heavily settled and farmed.

Catalog plants suited to this ecoregion

Computed from each plant's stated USDA zone range against this ecoregion's CHELSA-derived current zone range, with the CHELSA mid-century warming delta applied for the projection. Plants whose stated range falls outside both the current and projected zone end up dropped; the rest land in one of the three buckets below.

Collections for this ecoregion

Curated multi-plant collections whose members all fit this ecoregion's zone range — no won't-grow members smuggled in. Overall fit class shown per collection is the weakest link across its members.
