Often times, nurseries and garden centers stock trees and shrubs that create major issues in nearby natural areas. Landscapers everywhere seek beautiful, unusual, exceptionally hardy, drought-tolerant, or fast-growing plants. Unfortunately, plants selected for their resilience may be invasive because of their adaptable nature. Plants selected for their aesthetic value may be hard to banish from garden centers even after their invasive tendencies are revealed. These plants are typically prolific seed-producers which birds deposit everywhere creating competition for native plants.<\/p>\n<p>Invasive species are damaging because they:<a href=\"https:\/\/www.purdue.edu\/fnr\/extension\/wp-content\/uploads\/2015\/05\/PlantingTrees.jpg\" data-rel=\"lightbox-image-0\" data-rl_title=\"\" data-rl_caption=\"\" title=\"\"><img loading=\"lazy\" decoding=\"async\" class=\"alignright size-medium wp-image-2680\" src=\"https:\/\/www.purdue.edu\/fnr\/extension\/wp-content\/uploads\/2015\/05\/PlantingTrees-300x197.jpg\" alt=\"\" width=\"300\" height=\"197\" srcset=\"https:\/\/www.purdue.edu\/fnr\/extension\/wp-content\/uploads\/2015\/05\/PlantingTrees-300x197.jpg 300w, https:\/\/www.purdue.edu\/fnr\/extension\/wp-content\/uploads\/2015\/05\/PlantingTrees.jpg 350w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<ul>\n<li>produce large numbers of new plants each season.<\/li>\n<li>tolerate many soil types and weather conditions.<\/li>\n<li>spread easily and efficiently, usually by wind, water, or animals.<\/li>\n<li>grow rapidly, allowing them to displace slower growing plants.<\/li>\n<li>spread rampantly when they are free of the natural checks and balances found in their native range.<\/li>\n<\/ul>\n<p>One of the worst offenders for invasive qualities is the Callery Pear. This ornamental pear, famous for its prolific white flowers in spring, creates a beautiful display in many landscapes. However, it is a poor choice for two major reasons. It is highly invasive and can take over entire natural areas with its heavy seed production. In addition, it is a very weak-wooded tree with poor branch structure, leaving it susceptible to splitting and breaking under heavy winds. Check out this publication for more information on the Callery Pear. \u00a0See <a href=\"https:\/\/youtu.be\/yvnd13TJUJc?si=PB95ENuMDYfbPJW6\" target=\"_blank\" rel=\"noopener\">Invasive Plant Species: Callery Pear<\/a> video for more information.<\/p>\n<p>To help prevent the spread of invasive species, choose plants wisely.
