Narrative

The native range for Osage-orange is reported from eastern Texas, southeastern Oklahoma, southwestern Arkansas, and the northwestern corner of Louisiana (Little, 1971). Historically and presently known for its extreme value as bow-wood and fence posts, Osage-orange represents one of the most widely planted tree species in the lower 48 US states as a living fence starting in the mid-1800's, in the late 1900's as a landscape tree for difficult sites, and most recently it's chemical properties. Detailed history of Osage-orange and it's economic uses are well documented (Smith and Perino, 1981 and J. T. Winberry 1979). Osage wood is highly-prized for its use as fence posts (both living and non-living) and durable wood for wood working. Osage is an extremely drought and heat tolerant tree and is recommended for use in USDA cold-hardiness zones 5b or warmer. Although the species is commonly known for it's stout thorns and large, globular fruits, the species is dioecious and the degree of thorns on individual genotypes can be extremely variable. In the 1970's Al Ferguson (Iowa Arboretum) and John Pair (Kansas State University) evaluated select clones, typically thornless, male selections that were acquired across portions of the Midwest. Based on notes by Ferguson, a total of "5 clones were collected along highway 21 north of What Cheer in Keokuk County Iowa with two clones named Keokuk and What Cheer selected for further evaluation" due to vigor and "relatively thornless" and "all male". This accession represents the selection Keokuk, a clonal, thornless male.
