Eryngium leavenworthii is an annual plant known commonly as Leavenworth's eryngo. It is native to the central United States. It reaches heights of up to 3 feet that inhabits dry rocky prairies, roadside fields, open woodlands and waste areas. It is mostly seen flowering between July to September, however in some areas it has been seen blooming as late as November. The flowers are atop spiked leaves and elongated stems and form cones of purple or wine colored, tightly clustered blossoms that resemble fuzzy pineapples. The plant is mostly found in areas with limestone or chalk soils. It is in the parsley family and was named after its discoverer, Melines Conklin Leavenworth (1796–1862).
