Espinal
Espinal
The Espinal forms a broad arc of dry, thorny country across the interior of central Argentina, running from central Santa Fe through Córdoba to the north of San Luis, within the Neotropic realm's temperate grasslands, savannas and shrublands. Its name means "thorny shrubland," and the vegetation is a mosaic of deciduous xerophytic woodland, palm groves, grassy savannas and bushy steppe, with mature stands dominated by Prosopis (the algarrobos, and the largely endemic caldén) alongside Acacia, hackberries (Celtis) and chañar (Geoffroea). The northern reaches are warm and humid with summer rains, grading drier and more variable toward the south. The ecoregion shelters threatened birds such as the yellow cardinal and Chaco eagle, and its Mar Chiquita Lake and Dulce River swamps are a Ramsar wetland that is key habitat for Neotropical birdlife. Centuries of cattle ranching and expanding irrigated agriculture have left the original woodland in scattered remnants, making the caldén forests a particular conservation concern.

Use this as the broad planting pattern for the region: Temperate prairies, steppes, and pampas of grasses and forbs with few trees, under continental climates of hot summers and cold winters. Their deep, fertile soils have made them among the most extensively converted biomes for agriculture. For garden decisions, pair that context with the plant list below, then narrow by your site's light, water, soil, and mature-size constraints.
