Migrants’ home gardens may be created from elements of both old and new landscapes. We assume that medicinal plant assemblages in migrants’ gardens are shaped by plant diversity and availability, therapeutic needs, and heritagization processes. Which of the factors prevail: those related to biodiversity and ecology, epidemiology, or heritage and memory? In this paper we offer new knowledge on the garden landscapes of the Global South. The research was conducted in the Atlantic Forest in Argentina. We surveyed 120 home gardens: 60 of transborder Paraguayan migrants, and 60 of transcontinental Europeans who arrived in Misiones, Argentina before WW2 and their descendants. We compared the richness, composition, medicinal uses, and the relationships of garden plants (via plant networks) between these groups, taking into account everyday scales and the transnational scale. Paraguayans cultivated and protected 137 species, predominantly native, and people of European origin 119 spp., native and exotic in similar proportions. The similarity in plant composition (68%) and the consensus in the medicinal use of plants (62%) were high between the migrant groups. Plant network analysis revealed many overlaps in assemblages of plants, but certain particularities of each group remained because of cultural expressions and therapeutic needs. This high level of similarity suggests that plant diversity, both native and allochthonous, shared concepts of illness, and the flux of knowledge between these groups was more significant than heritagization practices in shaping home gardens’ medicinal plant assemblages. People of Paraguayan and European origins do not make an active effort to convert their home gardens into heritage. Medicinal plants are connected to the lived emplacement—intimate daily practices—rather than to ethnic identity strategies. Nevertheless, the plant assemblages in gardens have been shaped by ecology, colonial legacy, nostalgia, and transfer of knowledge; therefore migrants’ home gardens can be considered heritage in a broad sense.

移民的家庭花园可以利用新旧景观的元素来建造。我们假设移民花园中的药用植物组合是由植物多样性和可用性、治疗需求和遗传过程决定的。哪些因素占主导地位：与生物多样性和生态、流行病学或遗产和记忆有关的因素？在本文中，我们提供了有关南半球花园景观的新知识。该研究是在阿根廷的大西洋森林进行的。我们调查了 120 个家庭花园：60 名跨境巴拉圭移民，以及 60 名二战前抵达阿根廷米西奥内斯的跨大陆欧洲人及其后代。我们比较了这些群体之间园林植物的丰富度、组成、药用用途和关系（通过植物网络），同时考虑到日常规模和跨国规模。巴拉圭人培育并保护了 137 种物种，其中主要是本地物种，而欧洲人则培育和保护了 119 种物种，其中本地物种和外来物种的比例相似。迁徙群体之间植物成分的相似性（68%）和植物药用的一致性（62%）很高。植物网络分析揭示了植物组合中的许多重叠，但由于文化表达和治疗需求，每个组的某些特殊性仍然存在。这种高度的相似性表明，植物多样性，无论是本地植物还是外来植物，都具有共同的疾病概念，以及这些群体之间的知识流动，在塑造家庭花园的药用植物组合方面比传承实践更重要。巴拉圭人和欧洲人并没有积极努力将他们的家庭花园变成遗产。药用植物与居住环境（亲密的日常实践）相关，而不是与种族认同策略相关。然而，花园中的植物组合是由生态、殖民遗产、怀旧和知识转移塑造的。因此，移民家庭花园可以被视为广义上的遗产。
