1. 观赏园艺是全球植物入侵的最重要途径。大量非本地植物被用作观赏植物，而现行政策未能有效解决物种持续逃逸的问题。立法措施通常仅限于列出少数禁止销售或种植的高风险物种。然而，这种方法可能会给人这样的印象：未列出的物种不被认为是一种风险，因此可以安全使用。继续广泛使用尚未确定为具有入侵风险的物种可能会在未来产生问题。2。本文认为，从旨在识别物种入侵特征及其入侵成功因素的研究中获得的知识也可用于识别入侵风险较低的物种，并可推荐给园艺贸易、园林绿化部门和园丁以更安全地使用。3。将非入侵物种列入绿色名录的标准包括足够长的停留时间、高繁殖压力、其他地方没有入侵事件的记录以及对气候变化具有一定鲁棒性的迹象。提供了英国使用的观赏物种的随机样本的示例。4。合成与应用。迫切需要防止观赏园艺造成的进一步植物入侵。一份被评估为逃离种植风险较低的非本地观赏物种绿色名录将有助于防止植物入侵。尚未评估的物种将来可能具有入侵性，这样就可以更容易地避免。该列表在大规模种植和景观美化项目中特别有用。目前，政策通常侧重于（i）已经引入并被视为入侵的物种和（ii）防止新引入的潜在进一步入侵。这项研究表明，关注该国已经存在并广泛用于园艺的非入侵物种有助于推进处理入侵观赏物种的政策。
1. Ornamental horticulture is the most important pathway for plant invasions world-wide. Large numbers of non-native plants are used as ornamentals, and current policies fail to effectively address the continued escape of species from cultivation. Legislative measures are often limited to the listing of few high-risk species banned from sale or planting. This approach, however, may give the impression that non-listed species are not considered to be a risk and are therefore safe to use. The continued widespread use of species not yet identified as having the risk to become invasive may create a problem in the future.2. This article argues that knowledge gained from studies designed to identify invasive traits of species and factors contributing to their invasion success can also be used to identify species with a low invasion risk that can be recommended to the horticultural trade, landscaping sector and gardeners for safer use.3. The criteria identified for non-invading species to be listed in a green list include sufficiently long residence time, high propagule pressure, no records of invasive occurrences elsewhere and an indication of some robustness to climate change. An example is provided for a random sample of ornamental species used in Britain.4. Synthesis and application. There is a pressing need to prevent further plant invasions resulting from ornamental horticulture. A green list of non-native ornamental species that have been assessed as having a low risk of escaping cultivation will contribute to the prevention of plant invasions. Species not yet assessed which may have the potential to become invasive in the future can then be more easily avoided. This list would be particularly useful in large-scale plantings and landscaping projects. Currently, policies often focus on (i) species that are already introduced and recognized as invasive and (ii) the prevention of potential further invasions from new introductions. This study suggests that attention to non-invasive species already present in the country and widely used in horticulture can help to advance policies for dealing with invasive ornamental species.
