Lower branches\noften sweep near to the ground. It is also often seen as a tall, flat-topped\nshrub. This native hawthorn grows naturally from Quebec to North Carolina and\nKansas (USDA hardiness zones 3-7). <\/p>\n\n\n\n<p>Obovate to oblong-obovate dark green 2- 3\u201d long leaves\nturn to a striking red\/orange in the fall. The 3 inch wide white corymb flowers\nbloom in May over period of 7-10 days. Flowers emit an unpleasant peppery odor.\nFlowers are followed by rounded fruits (3\/8\u201d diameter) that ripen to deep red\nin fall (September-October) and typically persist to late fall. The tiny fruits\n(called \u201chaws\u201d) are edible, but the amount of pulp is not much and is best left\nfor the birds. <br>\n<br>\n&#8216;Cruzam&#8217; is commonly sold under the name of Crusader\u2122 as a thornless plant with\na slightly more compact shape. What distinguishes the thornless Crusader form is\nthe absence of thorns from the species. In my opinion the species should never\nbe planted in any public grounds and residential safety considerations. Crusader\nis a welcome alternative. Thornless tree makes plant general maintenance such\nas pruning alot. Crusader is rated a superior landscape tree.<\/p>\n\n\n\n<p>Cockspur hawthorn performs best if grown in full sunlight and any average\nwell-drained soil. It is very adaptable to both dry and moist growing\nconditions. It is highly tolerant of urban pollution and will even thrive in\ninner city environments. The tree needs occasional maintenance and is best\npruned in late winter once the threat of extreme cold has passed. It has no\nsignificant negative characteristics<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"678\" src=\"https:\/\/whatgrowsthere.com\/grow\/wp-content\/uploads\/2019\/07\/Crataegus-crusgalli-2-1024x678.jpg\" alt=\"\" class=\"wp-image-11948\" srcset=\"https:\/\/whatgrowsthere.com\/grow\/wp-content\/uploads\/2019\/07\/Crataegus-crusgalli-2-1024x678.jpg 1024w, https:\/\/whatgrowsthere.com\/grow\/wp-content\/uploads\/2019\/07\/Crataegus-crusgalli-2-300x199.jpg 300w, https:\/\/whatgrowsthere.com\/grow\/wp-content\/uploads\/2019\/07\/Crataegus-crusgalli-2-768x509.jpg 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption>Species has 2-3 inch long thorns <\/figcaption><\/figure>\n\n\n\n<p>Pests and diseases are a problem with most hawthorns. Plants are susceptible to cedar-hawthorn rust and fireblight. Other potential diseases include fungal leaf spots, powdery mildew, cankers, apple scab, leaf blight and twig blight. Potential insect pests include aphids, borers, caterpillars, lacebugs, leafminers and scale. <br> <br>Small flowering landscape tree for lawns or open woodland areas. Notwithstanding disease susceptibility, a well-maintained tree can be ornamentally attractive. On species plants, thorns are a drawback for pedestrian areas or areas with small children. Plants may be effective when grown as barrier plants on property borders or in hedgerows.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>n Cockspur thorn (Crataegus crus-galli) is sometimes seen as a dense, low-branched, broad-rounded tree to 25-35 feet with horizontal branching armed with numerous large 1.5 to 3 inch long thorns.
