Abstract

The ornamental horticulture industry has long been significant in its vast economic contributions to the US agricultural sector, with Florida ranking second in nursery and greenhouse plant sales. A small proportion of introduced plants eventually escape cultivation and become invasive, leaving fragile ecosystems at risk. In response, a series of propagation and production research studies have been conducted over the years to 1) evaluate the female sterility and landscape performance of cultivars and/or hybrids of ornamental invasives, and 2) develop reliable propagation systems of novel or underused natives having ornamental and ecological value. Attractive, fruitless selections of popular species such as butterfly bush (Buddleja sp.), heavenly bamboo (Nandina domestica), Mexican petunia (Ruellia simplex), lantana (Lantana strigocamara), trailing lantana (Lantana montevidensis), privet (Ligustrum sp.), maiden silvergrass (Miscanthus sp.), and fountain grass (Pennisetum sp.) have been identified as suitable non-native alternatives to the invasive or potentially invasive resident species (wild type). Simultaneously, researchers have taken a closer look at native plant alternatives that may offer similar aesthetic traits as invasive plants, while bringing added biodiversity and function for more ecologically friendly landscapes and gardens. As such, successful multisite trialing and/or propagation systems have been developed for a number of species native to Florida, such as squareflower (Paronychia erecta), coastalplain honeycombhead (Balduina angustifolia), wireweeds (Polygonella sp.), blue porterweed (Stachytarpheta jamaicensis), wild coffees (Psychotria sp.), sweet acacia (Vachellia farnesiana), and wild lime (Zanthoxylum fagara). With pronounced marketing and consumer education, it is hopeful that together sterile cultivars and native species will ultimately replace wild-type forms of commercially available ornamental invasives. This paper summarizes the current status of ornamental invasives in Florida and the role of native species and sterile non-native cultivars.
佛罗里达州的观赏入侵植物与研究建立的替代品
长期以来,观赏园艺业对美国农业部门的巨大经济贡献一直很重要,佛罗里达州在苗圃和温室植物销售方面排名第二。一小部分引进的植物最终逃离种植并成为入侵植物,使脆弱的生态系统面临风险。作为回应,多年来进行了一系列繁殖和生产研究,以1)评估观赏入侵品种和/或杂交种的雌性不育性和景观表现,以及2)开发具有观赏和生态价值的新的或未充分利用的本地品种的可靠繁殖系统。热门物种的吸引人的无果选择,如蝴蝶丛(Buddleja sp.)、天竹(Nandina domestica)、墨西哥矮牵牛(Ruellia simplex)、大花(lantana strigocamara)、蔓生大花(lantana montevidensis)、女贞(女贞属sp.),和喷泉草(Pennisetum sp.)已被确定为入侵或潜在入侵的常驻物种(野生型)的合适的非本土替代品。与此同时,研究人员对本土植物的替代品进行了更深入的研究,这些替代品可能提供与入侵植物相似的美学特征,同时为更生态友好的景观和花园带来更多的生物多样性和功能。因此,已经为许多原产于佛罗里达州的物种开发了成功的多站点试验和/或繁殖系统,如方形花(Paronychia erecta)、海岸平原蜜瓜(Balduina angustifolia)、杂草(Polygonella sp.)、蓝porterweed(Stachytarpheta jamaicensis)、野生咖啡(Psychotria sp.),和野生酸橙(Zanthoxylum fagara)。随着明显的市场营销和消费者教育,不育品种和本土物种有望最终取代野生型商业观赏入侵物种。本文综述了佛罗里达州观赏入侵的现状,以及本地物种和不育非本地品种的作用。
