It was introduced to Canada as a contaminant of crop seed in the late 18th century. An aggressive weed that spreads both by seed and extensive root systems, Canada thistle first establishes itself in disturbed soils.<\/p>\n<p>Growth Habit: Perennial, erect, up to 4 feet tall. Forms dense colonies with roots that grow horizontally sending up shoots along their length.<br \/>\nLeaves: Varies from light to dark green, oblong or lance shaped, deeply cut, spiny toothed margins (some may be smooth); slightly hairy below. Tremendous leaf variability.<br \/>\nFlower: Small bristly clusters, 3\/8 to 5\/8 inches in diameter, light lavender to deep rose purple. Plants are male or female. Asexual reproduction makes it possible for a colony of male plants to maintain itself. Flowering occurs June to August.<\/p>\n<p>Seeds: Smooth, light to dark brown, tipped by a cupped conical point, approximately 1\/8 inch long.<\/p>\n<p>Roots: Extensive, fleshy, creeping rootstocks. The roots produce numerous new plants each spring. Broken roots can grow new plants so plowing or roto-tilling will increase the population. Although the plants may appear to be separate they are typically connected by an underground root system.<\/p>\n"},"caption":{"rendered":"<p>Canada Thistle<\/p>\n"},"alt_text":"Canada Thistle","media_type":"image","mime_type":"image\/jpeg","media_details":{"width":182,"height":273,"hwstring_small":"height='96' width='62'","file":"2011\/12\/canadathistle-e1531411585814.jpg","sizes":{"thumbnail":{"file":"canadathistle-e1531411585814-150x150.jpg","width":150,"height":150,"mime_type":"image\/jpeg","source_url":"https:\/\/www.carboncountyweed.com\/wp-content\/uploads\/2011\/12\/canadathistle-e1531411585814-150x150.jpg"},"post-thumbnail":{"file":"canadathistle-194x198.jpg","width":"194","height":"198","source_url":"https:\/\/www.carboncountyweed.com\/wp-content\/uploads\/2011\/12\/canadathistle-194x198.jpg"},"widget-thumb":{"file":"canadathistle-e1531411585814-80x50.jpg","width":80,"height":50,"mime_type":"image\/jpeg","source_url":"https:\/\/www.carboncountyweed.com\/wp-content\/uploads\/2011\/12\/canadathistle-e1531411585814-80x50.jpg"},"full":{"file":"canadathistle-e1531411585814.jpg","width":182,"height":273,"mime_type":"image\/jpeg","source_url":"https:\/\/www.carboncountyweed.com\/wp-content\/uploads\/2011\/12\/canadathistle-e1531411585814.jpg"}},"image_meta":{"aperture":"0","credit":"","camera":"","caption":"","created_timestamp":"0","copyright":"","focal_length":"0","iso":"0","shutter_speed":"0","title":""}},"post":null,"source_url":"https:\/\/www.carboncountyweed.com\/wp-content\/uploads\/2011\/12\/canadathistle-e1531411585814.jpg","_links":{"self":[{"href":"https:\/\/www.carboncountyweed.com\/index.php?rest_route=\/wp\/v2\/media\/143","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.carboncountyweed.com\/index.php?rest_route=\/wp\/v2\/media"}],"about":[{"href":"https:\/\/www.carboncountyweed.com\/index.php?rest_route=\/wp\/v2\/types\/attachment"}],"author":[{"embeddable":true,"href":"https:\/\/www.carboncountyweed.com\/index.php?rest_route=\/wp\/v2\/users\/1"}]}}
