There is a good side and a bad side, shown especially when they escape the landscape and spread to our native areas, becoming invasive. When it comes to invasive plants in landscapes, there is good news and bad news. The bad news is that invasive plants are planted intentionally as ornamentals, and several species known to be invasive are readily available for sale from nurseries and garden centers. The good news is that there are many beautiful plants to choose from that are not invasive. Indeed, while many of the most picturesque garden plants are not native to the Midwest, the majority are not invasive. For example, hosta, smoke tree, boxwoods, Japanese tree lilacs, and dwarf shrub junipers are all non-native to the region but are not known to be invasive. However, brad ford pear, red barberry, burning bush and other \u201cgo-to\u201d landscape plants are damaging our natural ecosystem by establishing themselves where they really aren\u2019t welcome. These plants should be avoided and even considered for removal and replacement.<\/p>\n<div style=\"clear: both\"><\/div>\n<div id=\"attachment_14119\" style=\"width: 260px\" class=\"wp-caption alignleft\"><a href=\"https:\/\/www.purdue.edu\/fnr\/extension\/wp-content\/uploads\/2020\/04\/Screen-Shot-2020-04-08-at-6.15.59-PM.png\" data-rel=\"lightbox-image-0\" data-rl_title=\"InvasiveSpecies2\" data-rl_caption=\"InvasiveSpecies2\" title=\"InvasiveSpecies2\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-14119\" class=\"wp-image-14119\" src=\"https:\/\/www.purdue.edu\/fnr\/extension\/wp-content\/uploads\/2020\/04\/Screen-Shot-2020-04-08-at-6.15.59-PM-150x150.png\" alt=\"callery pears2\" width=\"250\" height=\"189\" srcset=\"https:\/\/www.purdue.edu\/fnr\/extension\/wp-content\/uploads\/2020\/04\/Screen-Shot-2020-04-08-at-6.15.59-PM-500x377.png 500w, https:\/\/www.purdue.edu\/fnr\/extension\/wp-content\/uploads\/2020\/04\/Screen-Shot-2020-04-08-at-6.15.59-PM-250x189.png 250w, https:\/\/www.purdue.edu\/fnr\/extension\/wp-content\/uploads\/2020\/04\/Screen-Shot-2020-04-08-at-6.15.59-PM.png 538w\" sizes=\"auto, (max-width: 250px) 100vw, 250px\" \/><\/a><p id=\"caption-attachment-14119\" class=\"wp-caption-text\">After their seeds are disseminated, callery pears can invade natural and disturbed areas.<\/p><\/div>\n<div id=\"attachment_14118\" style=\"width: 260px\" class=\"wp-caption alignleft\"><a href=\"https:\/\/www.purdue.edu\/fnr\/extension\/wp-content\/uploads\/2020\/04\/Screen-Shot-2020-04-08-at-6.15.46-PM.png\" data-rel=\"lightbox-image-1\" data-rl_title=\"invasiveSpecies\" data-rl_caption=\"invasiveSpecies\" title=\"invasiveSpecies\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-14118\" class=\"wp-image-14118\" src=\"https:\/\/www.purdue.edu\/fnr\/extension\/wp-content\/uploads\/2020\/04\/Screen-Shot-2020-04-08-at-6.15.46-PM-150x150.png\" alt=\"callery pears1\" width=\"250\" height=\"188\" srcset=\"https:\/\/www.purdue.edu\/fnr\/extension\/wp-content\/uploads\/2020\/04\/Screen-Shot-2020-04-08-at-6.15.46-PM-500x377.png 500w, https:\/\/www.purdue.edu\/fnr\/extension\/wp-content\/uploads\/2020\/04\/Screen-Shot-2020-04-08-at-6.15.46-PM-250x188.png 250w, https:\/\/www.purdue.edu\/fnr\/extension\/wp-content\/uploads\/2020\/04\/Screen-Shot-2020-04-08-at-6.15.46-PM.png 536w\" sizes=\"auto, (max-width: 250px) 100vw, 250px\" \/><\/a><p id=\"caption-attachment-14118\" class=\"wp-caption-text\">Many callery pears can produce abundant fruit<br \/>that are widely distributed by birds<\/p><\/div>\n<div style=\"clear: both\"><\/div>\n<div id=\"attachment_10647\" style=\"width: 260px\" class=\"wp-caption alignleft\"><a href=\"https:\/\/www.purdue.edu\/fnr\/extension\/wp-content\/uploads\/2018\/05\/Fig-2-5480375-e1528379808371.jpg\" data-rel=\"lightbox-image-2\" data-rl_title=\"Invasive&#8217;s leaves (figure 2)\" data-rl_caption=\"Invasive&#8217;s leaves (figure 2)\" title=\"Invasive&#8217;s leaves (figure 2)\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-10647\" class=\"wp-image-10647\" src=\"https:\/\/www.purdue.edu\/fnr\/extension\/wp-content\/uploads\/2018\/05\/Fig-2-5480375-150x150.jpg\" alt=\"Invasive's leaves (figure 2)\" width=\"250\" height=\"188\" \/><\/a><p id=\"caption-attachment-10647\" class=\"wp-caption-text\">Mile-a-minute vine grows more than 25 feet in height in one growing season while covering and smothering forest trees.<\/p><\/div>\n<div id=\"attachment_8711\" style=\"width: 260px\" class=\"wp-caption alignleft\"><a href=\"https:\/\/www.purdue.edu\/fnr\/extension\/wp-content\/uploads\/2017\/04\/Invasive-Plant-1.png\" data-rel=\"lightbox-image-3\" data-rl_title=\"Invasive Plant 1\" data-rl_caption=\"Invasive Plant 1\" title=\"Invasive Plant 1\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-8711\" class=\"wp-image-8711\" src=\"https:\/\/www.purdue.edu\/fnr\/extension\/wp-content\/uploads\/2017\/04\/Invasive-Plant-1-150x150.png\" alt=\"Invasive Plant 1\" width=\"250\" height=\"296\" srcset=\"https:\/\/www.purdue.edu\/fnr\/extension\/wp-content\/uploads\/2017\/04\/Invasive-Plant-1-253x300.png 253w, https:\/\/www.purdue.edu\/fnr\/extension\/wp-content\/uploads\/2017\/04\/Invasive-Plant-1-250x296.png 250w, https:\/\/www.purdue.edu\/fnr\/extension\/wp-content\/uploads\/2017\/04\/Invasive-Plant-1.png 339w\" sizes=\"auto, (max-width: 250px) 100vw, 250px\" \/><\/a><p id=\"caption-attachment-8711\" class=\"wp-caption-text\">Garlic mustard produces chemicals that inhibit the growth of other plants.<\/p><\/div>\n<div style=\"clear: both\"><\/div>\n<p>Several professional landscape and nursery organizations have taken the charge in eliminating these harmful plants. They believe invasive species adversely affect the integrity of ecosystems and cause both environmental degradation and economic harm. Invasive species &#8211; whether they are plants, animals, fungi, or insects &#8211; may cause deterioration of native habitats and plant communities as well as damage to designed and managed ecosystems. Because invasives reduce biodiversity and disrupt the healthy structure and function of both native and human ecosystems, planners, contractors, arborists, landscape architects and other green industry professionals should not introduce or support the use of known invasive species. And, where they are already existing, steps should be taken to eradicate them.<\/p>\n<p>Read the publication <a href=\"https:\/\/edustore.purdue.edu\/item.asp?Item_Number=ID-464-W\" target=\"_blank\" rel=\"noopener noreferrer\">Commercial Greenhouse and Nursery Production: Alternative Options for Invasive Landscape Plants<\/a> for more information.
