The individual flowers have 5 shallowly to deeply notched petals, 5 sepals, and 5 stamens. The flowers are followed by flat, green, egg-shaped to somewhat heart-shaped fruits with a parsley-like scent. From a distance, the fruit umbels look like green flowers. The leaves are basal and alternate, round to kidney-shaped, and ternate with 3 dark green, toothed and lobed main lobes.

Skin contact with juice from the plant followed by exposure to sunlight can cause photodermatitis, which can range from a mild, red rash to severe skin blistering. Wear gloves when cutting or weeding this plant, promptly wash off any sap, and keep any affected areas out of direct sunlight. Merely touching this plant should not cause any harm because the phototoxins are in the sap.<\/p>\n Classification<\/p>\n Kingdom:<\/span> Plantae – Plants More About This Plant<\/p>\n Arizona County Distribution Map<\/a> View photographs and a description of the plant Heracleum maximum, commonly known as Common Cowparsnip, Cow Parsnip, or Cow-parsnip<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[48,146,145,17,34,24,29,36,33,225,10,169],"tags":[],"class_list":["post-2699","post","type-post","status-publish","format-standard","hentry","category-apiaceae-carrot-family","category-foul-smelling-flowers-and-plants","category-fragrant-flowers-and-plants","category-herbs-and-forbs","category-mountain-plants","category-native-wildflowers-and-plants","category-perennials","category-poisonous-plants","category-riparian-and-wetland-plants","category-summer-blooming-plants","category-white-arizona-flowers","category-white-flowers"],"_links":{"self":[{"href":"https:\/\/www.fireflyforest.com\/flowers\/wp-json\/wp\/v2\/posts\/2699","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.fireflyforest.com\/flowers\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.fireflyforest.com\/flowers\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.fireflyforest.com\/flowers\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.fireflyforest.com\/flowers\/wp-json\/wp\/v2\/comments?post=2699"}],"version-history":[{"count":6,"href":"https:\/\/www.fireflyforest.com\/flowers\/wp-json\/wp\/v2\/posts\/2699\/revisions"}],"predecessor-version":[{"id":3118,"href":"https:\/\/www.fireflyforest.com\/flowers\/wp-json\/wp\/v2\/posts\/2699\/revisions\/3118"}],"wp:attachment":[{"href":"https:\/\/www.fireflyforest.com\/flowers\/wp-json\/wp\/v2\/media?parent=2699"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.fireflyforest.com\/flowers\/wp-json\/wp\/v2\/categories?post=2699"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.fireflyforest.com\/flowers\/wp-json\/wp\/v2\/tags?post=2699"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
